The front side including the rear seat 4 provided immediately before the cargo compartment 2 is a passenger compartment 3. The rear seat 4 includes a seat cushion 4a, a seat back 4b whose lower end portion is supported by a floor panel 21 described later via a bracket (not shown) so as to be rotatable about an axis extending in the vehicle width direction, and the seat back And a headrest 4c attached to the upper end of 4b. The seat back 4b is divided into two parts on the left and right sides (see FIG. 2), which are pivotable independently of each other, and are in a standing state in which a passenger of the vehicle 1 can be seated, and lying down on the seat cushion 4a Rotate between states. Note that front, rear, left, and right in the present specification refer to the front, rear, left, and right of the vehicle 1, respectively.

  The vehicle 1 is a hatchback type, and a rear opening 7 (see FIGS. 6, 8, and 10) is provided on the rear surface of the vehicle 1 so as to communicate with the luggage compartment 2. A back door 8 is provided to cover the opening 7 so as to be opened and closed. The back door 8 is supported so as to be rotatable around a hinge shaft 9 provided at an upper end portion thereof. The hinge shaft 9 is supported by a rear end portion of a rear header 11 provided at the rear end portion of the roof panel 10 so as to extend in the vehicle width direction. Thus, the back door 8 opens and closes the rear opening 7 by turning around the hinge shaft 9. The back door 8 is opened and closed manually by an occupant of the vehicle 1, but may be driven by an electric motor. The back door 8 is provided in a portion excluding the main body 8a having a window opening 8b in the upper portion, the window glass 8c provided in the window opening 8b, and the window opening 8b on the cargo compartment 2 side (front side) of the main body 8a. Door trim 8d. The door trim 8 d corresponds to the rear wall of the luggage compartment 2 and is one member that forms the luggage compartment 2. Then, by opening the back door 8, the cargo compartment 2 is opened rearward through the rear opening 7, and the occupant can take in and out the luggage with respect to the cargo compartment 2 through the rear opening 7.

  The bottom wall (loading room floor) of the loading room 2 is composed of a floor board 15. The floor board 15 is composed of two upper and lower resin plates. A storage chamber 16 for storing the spare tire 17 is disposed below the floor board 15. The storage chamber 16 is composed of a recess 21 a formed to be recessed downward in the floor panel 21 extending from the passenger compartment 3 side, and the floor board 15 provided so as to close the opening of the recess 21 a. Yes. The floor board 15 is bent at two places in the front-rear direction, and an occupant can lift the rear part of the floor board 15 to open the upper side of the accommodation chamber 16. There are also vehicles that do not have spare tires 17 mounted thereon, and passengers can freely load luggage in the accommodation chamber 16 in such vehicles. For example, the tonneau cover 36 (see FIG. 11) folded as described below can be accommodated in the accommodation chamber 16.

  Although not shown on the left and right sides of the storage chamber 16, rear side frames extend in the front-rear direction, and the floor panel 21 is supported and fixed on both the rear side frames. A cross member 22 extending in the vehicle width direction is fixed to a portion of the lower surface of the floor panel 21 between the storage chamber 16 and the rear seat 4, and left and right ends of the cross member 22 are respectively attached to the rear side frames.

The reinforcement 25a of the rear bumper 25 is fixed to the left and right rear side frames via a crash can (not shown) provided at the rear end of each rear side frame.

  The rear end portion of the floor panel 21 rises from the height position of the bottom surface of the storage chamber 16 and is positioned at substantially the same height position as the floor board 15, and is the lower edge of the rear opening portion 7. A striker 27 that is engaged with a latch mechanism (not shown) provided at the lower end portion of the main body portion 8 a of the back door 8 is disposed at the rear end portion of the floor panel 21. The rear end portion of the floor panel 21 and the vicinity thereof are reinforced by a reinforcing member 28. A muffler (a lower position of the storage chamber 16), a fuel tank (a lower position of the rear seat 4), and the like are disposed below the floor panel 21, but the description thereof is omitted.

  The left and right side walls of the cargo compartment 2 are respectively constituted by left and right side wall trims 31. In each side wall trim 31, at the substantially same height position as the lower edge of the window opening 8b of the back door 8 in the closed state (it is also substantially the same height position as the upper end of the seat back 4b of the rear seat 4 in the standing state). Is formed such that a stepped portion 31a (see FIGS. 2, 3 and the like) extends in the front-rear direction, and the lower side portion of the side wall trim 31 with respect to the stepped portion 31a is on the inner side in the vehicle width direction than the upper portion (loading chamber 2 side). Front and rear support grooves 31b and 31c for supporting a tonneau cover 36, which will be described later, are formed at two positions before and after the front portion of the step portion 31a in each side wall trim 31 (see FIGS. 2 and 3). .

  The tonneau cover 36 of the tonneau cover device 35 is closed immediately above the upper end of the seat back 4b of the rear seat 4 in the upright position above the floor board 15 (the cargo floor). The back door 8 is provided so as to extend in a substantially horizontal state immediately before the lower edge of the window opening 8b. The tonneau cover 36 is used to prevent the luggage placed on the floor board 15 from being seen through the window opening 8b (window glass 8c) from the outside of the vehicle. From this point of view, the tonneau cover 36 is usually provided at a height position substantially the same as or lower than the lower edge of the window opening 8b of the back door 8 in the closed state. In this embodiment, when using the tonneau cover 36, the tonneau cover 36 is provided at substantially the same height as the lower edge of the window opening 8b of the back door 8 in the closed state so that the tallest possible load can be loaded.

  As shown in FIGS. 2, 4, and 5, the tonneau cover 36 includes a front cover 37 and a rear cover 38 that are positioned in the front-rear direction. The rear end of the front cover 37 and the front end of the rear cover 38 are connected to each other so as to be rotatable around an axis extending in the vehicle width direction. That is, the rear end of the front cover 37 and the front end of the rear cover 38 are connected via the two hinge members 41. Each hinge member 41 has two rotating pieces 41a and 41b that are configured to be rotatable around a rotating shaft 41c extending in the vehicle width direction. One rotating piece 41a is a front cover 37 (described later). The rear divided portion 37b) is fixed to the rear end portion of the lower surface with a screw 42, and the other rotating piece 41b is fixed to the front end portion of the lower surface of the rear cover 38 with a screw 42. The cover 38 and the cover 38 are rotatable relative to each other around the rotation shaft 41c (the rotation shafts 41c of the two hinge members 41 are located on the same straight line). A recess 39 is formed in the upper surface of the rear cover 38 at the center in the vehicle width direction and in the vicinity of the rear end so that the occupant can hook his / her finger. There is no need to operate.

  A torsion coil spring 43 is disposed around the rotation shaft 41c of each hinge member 41 (that is, a connecting portion between the rear end of the front cover 37 and the front end of the rear cover 38). The rear cover 38 is urged by the spring 43 so as to rotate counterclockwise in FIGS. 1 and 5 around the rotation shaft 41 c with respect to the front cover 37. When the front cover 37 is in a substantially horizontal state, the front end surface of the rear cover 38 abuts on the rear end surface of the front cover 37, and the rear cover 38 can further rotate with respect to the front cover 37. The rear cover 38 is also in a substantially horizontal state. However, strictly speaking, the rear cover 38 is slightly inclined downward toward the rear. Hereinafter, the time when the front cover 37 (a rear divided portion 37b described later) and the rear cover 38 are in a substantially horizontal state is referred to as an initial state.

  Further, the rear cover 38 can be rotated clockwise in FIGS. 1 and 5 around the rotation shaft 41c against the biasing force of the torsion coil spring 43, whereby the front cover 37 and the rear cover 38 can be rotated. The surfaces corresponding to the lower surface when the side cover 38 is in the initial state can be brought into contact with each other.

  The front cover 37 is divided into a front divided portion 37a and a rear divided portion 37b, and the rear end of the front divided portion 37a and the front end of the rear divided portion 37b are three hinges similar to the hinge member 41. The members 45 are connected to each other so as to be rotatable around an axis extending in the vehicle width direction. That is, the two rotating pieces 45a and 45b of each hinge member 45 are fixed to the rear end portion of the upper surface of the front-side divided portion 37a and the front end portion of the upper surface of the rear-side divided portion 37b by the screws 46, respectively. The portion 37a and the rear divided portion 37b are rotatable relative to each other around a rotation shaft 45c extending in the vehicle width direction of each hinge member 45 (the rotation shafts 45c of all the hinge members 45 are identical to each other). Located on the line). As a result, the rear dividing portion 37b can be rotated counterclockwise in FIGS. 1 and 5 around the rotation shaft 45c with respect to the front dividing portion 37a, and the rear end of the rear dividing portion 37b is It is possible to move upward with respect to the front end of the rear divided portion 37b. When the front-side divided portion 37a is in a substantially horizontal state, the rear-side divided portion 37b tends to rotate clockwise in FIGS. 1 and 5 around the rotation shaft 45c due to the weight of the rear-side divided portion 37b. The front end surface of the rear divided portion 37b comes into contact with the rear end surface of the front divided portion 37a, and the rear divided portion 37b cannot rotate with respect to the front divided portion 37a. It becomes horizontal.

  A front support shaft 48 and a rear support shaft 49 are respectively formed on the front end portion and the rear end portion of the left and right side surfaces of the front divided portion 37a of the front cover 37 so as to protrude outward in the vehicle width direction. Each front support shaft 48 is fitted into a front support groove 31b formed in the step portion 31a of each side wall trim 31, and each rear support shaft 49 is fitted into a rear support groove 31c formed in the step portion 31a. ing.

  As shown in FIG. 3, the front support groove 31b is recessed downward from the upper surface of the stepped portion 31a and is open to the upper surface of the stepped portion 31a and the inner surface in the vehicle width direction. The length in the front-rear direction of the front support groove 31 b is substantially the same as the diameter of the front support shaft 48. The rear support groove 31c includes an upper and lower slide part 31d that is recessed downward from the upper surface of the step part 31a, and a front and rear slide part 31d that is continuously recessed from the lower part of the upper and lower slide part 31d to the rear side. The vertical slide portion 31d has the same shape as the front support groove 31b, and is open to the upper surface of the step portion 31a and the inner surface in the vehicle width direction. The front / rear slide portion 31d is opened only on the inner surface in the vehicle width direction, and the length in the vertical direction is substantially the same as the diameter of the rear support shaft 49. Therefore, the rear support shaft 49 can slide in the front-rear direction when it is positioned at the front-rear slide portion 31d, but cannot move in the up-down direction. When the front support shaft 48 is fitted in the front support groove 31b, the rear support shaft 49 is located at the rear end portion of the front / rear slide portion 31d. In this state, since the front cover 37 itself cannot move in the front-rear direction, the rear support shaft 49 cannot move in the up-down direction or the front-rear direction. For this reason, unless the occupant lifts the front portion of the front divided portion 37a and removes the front support shaft 48 from the front support groove 31b as described later, the front divided portion 37a is supported and fixed to the step portion 31a.

  In the state where the front divided portion 37a is supported and fixed to the stepped portion 31a as described above, the front divided portion 37a is in a substantially horizontal state, and as described above, the rear divided portion 37b is also in a substantially horizontal state, As a result, the front cover 37 is in a substantially horizontal initial state. Further, as described above, the rear cover 38 is also in a substantially horizontal initial state. In this way, the entire tonneau cover 36 is supported substantially horizontally by the step portion 31 a via the front and rear support shafts 48.

  The tonneau cover device 35 includes an interlocking mechanism 51 that moves the front cover 37 in conjunction with the opening / closing operation of the back door 8. The interlocking mechanism 51 interlocks with the opening operation of the back door 8, and moves the front cover 37 from the initial state while the rear end of the front cover 37 is positioned forward of the rear opening 7. The front cover 37 is configured to move upward relative to the front end of the front cover 37 and to move the front cover 37 back to the initial state in conjunction with the closing operation of the back door 8. Here, in the present embodiment, due to the support structure for the step portion 31a of the front division portion 37a of the front cover 37, the front division portion 37a maintains a substantially horizontal state regardless of the operation of the interlocking mechanism 51, and the rear side The dividing portion 37b is moved by the interlocking mechanism 51. Thus, the rear divided portion 37b corresponds to a movable cover, and the front divided portion 37a corresponds to a fixed cover positioned in front of the movable cover.

  Specifically, the interlocking mechanism 51 has two interlocking wires 52 having one ends connected to the front cover 37. One ends of these two interlocking wires 52 are connected to the vicinity of the rear end of the rear divided portion 37b of the front cover 37 and the vicinity of the left and right ends, respectively. A wire attachment hole 54 penetrating in the thickness direction is formed at a connecting portion of the interlocking wire 52 in the rear divided portion 37b. The wire attachment hole 54 is formed at an intermediate portion 54a formed in the middle in the longitudinal direction, below the intermediate portion 54a, a large diameter portion 54b having a diameter larger than the diameter of the intermediate portion 54a, and an upper side of the intermediate portion 54a. And a tapered portion 54c having a diameter that increases toward the upper side. A fixing member 55 having a diameter larger than that of the intermediate portion 54a and smaller than that of the large diameter portion 54b is fixed to one end of the interlocking wire 52. The fixing member 55 is connected to a boundary portion between the intermediate portion 54a and the large diameter portion 54b. It is fixed. A lid member 56 is fitted into the large diameter portion 54b from the lower surface side of the rear divided portion 37b so that the large diameter portion 54b, the fixing member 55 and the like cannot be seen.

  The two interlocking wires 52 extend upward from the fixing member 55, pass through the intermediate portion 54a and the taper portion 54c to the upper surface side of the rear divided portion 37b, and extend upward and rearward therefrom, and the other ends thereof. The door trim 8d of the back door 8 is connected to the left and right side edges of the window opening 8c. That is, the other end of the interlocking wire 52 formed in a ring shape is formed at the side edge portions on the left and right sides of the window opening 8c of the door trim 8d of the back door 8 (position slightly above the vertical center of the window opening 8c). Connecting pins 59 for hooking and connecting are respectively formed protruding inward in the vehicle width direction. The tip of each connecting pin 59 is formed to have a larger diameter than the other parts, and the other end of each interlocking wire 59 is made difficult to come off from each connecting pin 59.

  When the back door 8 is in the fully closed state, the interlocking wire 52 is loose and the front cover 37 is in the initial state (see FIG. 1). Then, as the back door 8 opens, the position of the connecting pin 59 rises and eventually the interlocking wire 52 is in tension. When the back door 8 is further opened from this state, the rear end of the front cover 37 (rear end of the rear divided portion 37b) is pulled up by the interlocking wire 52, and the rear end of the front cover 37 (rear portion of the rear divided portion 37b). The rear end moves upward with respect to the front end of the front cover 37 (the entire front split portion 37a and the front end of the rear split portion 37b) (see FIGS. 6 and 7). That is, the rear divided portion 37b rotates around the rotation shaft 45c of the hinge member 45 counterclockwise in FIGS. Since the rear end of the rear split portion 37b (the rear end of the front cover 37) moves forward as it rises during the rotation of the rear split portion 37b, it is positioned in front of the rear opening 7. Thus, it does not protrude from the rear opening 7 to the outside of the cargo compartment 2 (outside the vehicle). In the fully opened state of the back door 8, the rotation angle of the rear division portion 37b (the amount of upward movement of the rear end of the rear division portion 37b) is maximized (the maximum rotation angle from the initial state of the rear division portion 37b is , Smaller than 90 °), the rear dividing portion 37b is inclined upward in the rearward direction in a side view of the vehicle (see FIGS. 8 to 10). When the rear divided portion 37b is rotated, the interlocking wire 52 is bent nearly 90 ° when it comes out above the wire mounting hole 54. However, the tapered portion 54c can bend smoothly. Yes.

  When the back door 8 is closed from the fully opened state, the rear divided portion 37b balances with the pulling force by the interlocking wire 52, and the weight of the rear divided portion 37b causes the rotating shaft 45c to rotate around the rotation shaft 45c. And the rear end of the rear split portion 37b is lowered. When the back door 8 is fully closed, the rear divided portion 37b is substantially horizontal, that is, the front cover 37 is returned to the initial state.

  In addition to the interlocking mechanism 51, the tonneau cover device 35 moves the rear cover 38 along with the movement of the front cover 37 by the interlocking mechanism 51 (upward movement of the rear end of the rear split portion 37b). A rear cover moving mechanism 61 is also provided for moving the rear end of the rear cover 38 from the initial state so as to move forward relative to the rear end of the front cover 37 that moves upward.

  Specifically, the rear cover moving mechanism 61 has two lead wires 62 having one end connected to the rear cover 38. These two lead-in wires 62 are connected to the vicinity of the front end of the rear cover 38 and the vicinity of the left and right ends, respectively. A wire attachment hole 54 similar to the connection portion of the interlocking wire 52 in the rear divided portion 37b is also formed in the connection portion of the drawing wire 62 in the rear cover 38. However, the wire attachment hole 54 of the rear cover 38 is upside down with respect to the wire attachment hole 54 of the rear divided portion 37b (the large diameter portion 54b is located above the intermediate portion 54a and is tapered. The portion 54c is positioned below the intermediate portion 54a, and the lid member 56 is fitted from the rear cover 38 side). The other wire connection configuration is the same as that of the rear divided portion 37b.

  The two lead wires 62 extend downward from the fixing member 55, pass through the intermediate portion 54a and the taper portion 54c to the lower surface side of the rear cover 38, extend downward and forward from there, and the other ends thereof The left and right side wall trims 31 (members forming the luggage compartment) are respectively connected to the front portion of the rear cover 38 (in the present embodiment, a position substantially directly below the rear support shaft 49). That is, at the position just below the rear support shaft 49 in the side wall trim 31, the connection pins 65 for hooking and connecting the other end of the pull-in wire 62 formed in a ring shape project inward in the vehicle width direction. Has been. The tip of each connecting pin 65 is formed to have a larger diameter than the other part, like the connecting pin 59 for connecting the other end of the interlocking wire 52, and the other end of each drawing wire 62 is connected to each other. The pin 65 is made difficult to come off.

  When the back door 8 is fully closed and the front cover 37 is in the initial state, the lead-in wire 62 is loosened, and the rear cover 38 is in the initial state by the torsion coil spring 43 (see FIG. 1). Then, as the rear end of the front cover 37 (the rear end of the rear divided portion 37b) rises, the connection position of the front end and the pull-in wire 62 in the rear cover 38 rises, and eventually the tension is generated in the pull-in wire 62 become. From this state, when the rear end of the front cover 37 further rises, the rear cover 38 is pulled forward by the pull-in wire 62 and resists the urging force of the torsion coil spring 43 to rotate around the rotation shaft 41 c. It rotates clockwise in FIGS. That is, the rear end of the rear cover 38 moves forward with respect to the rear end of the front cover 37 (rear divided portion 37b). Here, since the rear opening 7 is inclined forward toward the upper side, if the rear cover 38 does not rotate as described above, as shown by a two-dot chain line in FIG. As the rear end rises, the rear cover 38 also rises, and the rear end portion of the rear cover 38 projects from the rear opening 7 to the outside of the luggage compartment 2 (outside the vehicle). However, in the present embodiment, the rear cover 38 is pulled into the luggage compartment 2 in front of the rear opening 7 by the action of the pull-in wire 62, so that the rear cover 38 is loaded in addition to the front cover 37. It does not protrude outside the chamber 2.

  When the rear end of the rear divided portion 37b further rises, the rear end (rear end of the initial state) of the rear cover 38 moves to the front side from the rear end of the front cover 37 (rear end of the rear divided portion 37b). When the back door 8 is fully opened and the amount of upward movement of the rear end of the rear divided portion 37b is maximized, the surfaces corresponding to the lower surfaces of the front cover 37 and the rear cover 38 when they are in the initial state (In this embodiment, since the lead-in wire 62 is interposed between the front cover 37 and the rear cover 38, the surfaces come into contact with each other via the lead-in wire 62). That is, the rear cover 38 overlaps with the rear divided portion 37b in the thickness direction (the rear cover 38 extends along the rear divided portion 37b) (see FIGS. 8 and 9). Thereby, the length in the vertical direction of the rear opening of the lower portion of the cargo compartment 2 relative to the tonneau cover 36 (that is, the rear opening area of the lower portion of the cargo compartment 2 lower than the tonneau cover 36) is ensured to the maximum. Can do. That is, assuming that the state of FIG. 6 is the fully opened state of the back door 8, the rear end of the rear cover 38 is located on the rear side of the rear end of the front cover 37. The length in the vertical direction is L ', which is quite short (the rear opening area is small). On the other hand, as shown in FIG. 8, when the rear cover 38 overlaps the rear divided portion 37b in the thickness direction, the length of the rear opening in the vertical direction is larger than L ′. Thus, the rear opening area can be increased.

  In the fully open state of the back door 8, the surfaces corresponding to the lower surfaces of the front cover 37 and the rear cover 38 in the initial state are not necessarily in contact with each other, and the rear end of the rear cover 38 (in the initial state) It is only necessary that the rear end) is positioned on the front side of the rear end of the front cover 37. Even in this case, the vertical length (rear opening area) of the rear opening is close to L, and the rear opening area can be sufficiently secured.

  When the back door 8 is closed from the fully open state, the front cover 37 moves back to the initial state as described above (the rear end of the rear divided portion 37b is lowered), but with this return movement, the rear cover 38 is moved. However, while being balanced with the pulling force by the lead-in wire 62, the biasing force of the torsion coil spring 43 rotates around the rotation shaft 41c counterclockwise in FIG. 8 and FIG. Move backwards. When the back door 8 is fully closed, the rear cover 38 returns to the initial state as the front cover 37 returns to the initial state. Thus, the torsion coil spring 43 constitutes an urging means for moving the rear cover 38 back to the initial state as the front cover 37 returns to the initial state.

  In the present embodiment, the front cover 37 is divided into three substantially equally divided into the front divided portion 37a, the rear divided portion 37b, and the rear cover 38 in the front-rear direction. This is to enable compact storage when the tonneau cover 36 is removed. That is, the tonneau cover 36 is detachably attached to the step portion 31a of the left and right side wall trims 31 (members forming the cargo compartment), and the occupant removes or attaches the tonneau cover 36 as necessary. Can do. For example, when the height position of the upper end of the luggage placed on the floor board 15 is higher than the height positions of the front cover 37 and the rear cover 38 in the initial state, the tonneau cover 36 is removed from the step portion 31a. .

  To remove the tonneau cover 36 from the stepped portion 31a, first, the front side portion of the front side split portion 37a of the front cover 37 is lifted to remove the front side support shaft 48 from the front side support groove 31b, and then the front side split portion 37a (the whole tonneau cover 36). Is moved to the front side, the rear support shaft 49 is moved from the rear end portion of the front / rear slide portion 31e of the rear support groove 31c to the lower portion of the front vertical slide portion 31d. Then, by lifting the rear portion of the front divided portion 37b, the rear support shaft 49 is moved to the upper side of the vertical slide portion 31d and removed from the rear support groove 31c. Further, the interlocking wire 52 and the drawing wire 62 are removed from the connecting pins 59 and 65, respectively. In this way, the tonneau cover 36 can be removed.

  As shown in FIG. 11, the tonneau cover 36 thus removed is folded so that the front divided portion 37 a, the rear divided portion 37 b and the rear cover 38 of the front cover 37 overlap each other in the thickness direction. At this time, the interlocking wire 52 and the pulling wire 62 are wound around and fixed to the folded tonneau cover 36 so that the rear cover 38 is not rotated and unfolded by the torsion coil spring 43 (in FIG. 11, the interlocking wire 52 and the pulling wire are connected). 62 is omitted). Alternatively, if the folded tonneau cover 36 is placed on the floor board 15 or the like so that the rear cover 38 is on the lower side, the rear cover 38 does not expand due to the weight of the front cover 37.

  On the other hand, to attach the tonneau cover 36 to the stepped portion 31a, the rear support shaft 49 of the front divided portion 37a of the front cover 37 is fitted into the upper and lower slide portions 31d of the rear support groove 31c and the rear slide portion 31e is then moved from there. After moving to the end, the front support shaft 48 is fitted into the front support groove 31b. Further, the interlocking wire 52 and the drawing wire 62 are attached to the connecting pins 59 and 65, respectively. Thus, the attachment of the tonneau cover 36 is completed.

  The front divided portion 37a and the rear divided portion 37b of the front cover 37 are made of a board in which a vinyl layer, a hard layer (made of a resin such as polycarbonate) and a nonwoven fabric layer are laminated in the thickness direction in order from the top (in the drawing) The thickness of the board is about 10 mm. Since the hard layer is relatively thick, the front cover 37 (the front divided portion 37a and the rear divided portion 37b) does not have flexibility.

  On the other hand, the rear side cover 38 has flexibility. In the present embodiment, the rear cover 38 is also composed of a three-layer board made of the same material as the front cover 37, but the thickness of the hard layer of the rear cover 38 is thinner than the thickness of the hard layer of the front cover 37. Thus, the rear cover 38 is flexible. Then, the thickness of at least one of the vinyl layer and the nonwoven fabric layer is increased by the thickness of the hard layer of the rear cover 38, and the thickness of the rear cover 38 is the same as the thickness of the front cover 37 (about 10 mm). I have to. The thickness of the rear cover 38 is set to be smaller than that of the front cover 37 by making the thickness of the hard layer of the rear cover 38 thinner than the thickness of the hard layer of the front cover 37. It may be thinner than the thickness. Alternatively, the thickness of each layer of the rear cover 38 may be the same as that of the front cover 37, and the material of the hard layer of the rear cover 38 may be different from the hard layer of the front cover 37 (a material that is easily bent). Further, the front cover 37 and the rear cover 38 are not limited to the three-layer configuration. Furthermore, the front cover 37 and the rear cover 38 are not limited to the form of the board as described above.

  Since the rear cover 38 is flexible as described above, the rear portion of the rear cover 38 is placed on the luggage 70 (for example, the floor board 15) loaded in the luggage compartment 2, as shown in FIG. Even if the height position of the upper end abuts against a load (which is slightly lower than the height position of the rear cover 38 in the initial state), the rear cover 38 can move while curving. In addition, it is possible to avoid problems caused by the interference between the rear cover 38 and the luggage 70.

  Therefore, in the present embodiment, when the back door 8 is opened and closed and fully opened, the rear end of the rear divided portion 37b (the rear end of the front cover 37) protrudes from the rear opening 7 to the outside of the luggage compartment 2 (outside the vehicle). In addition, the rear cover 38 is not drawn into the cargo compartment 2 and protrudes outside the cargo compartment 2. In the fully opened state of the back door 8, the rear cover 38 is overlapped with the rear divided portion 37b in the thickness direction, so that the rear opening area of the lower portion of the luggage compartment 2 below the tonneau cover 36 is maximized. It is possible to prevent the rear cover 38 from interfering with loading / unloading of the luggage into / from the luggage compartment 2 as much as possible. Further, since the movement of the front cover and the rear cover is performed in conjunction with the opening / closing operation of the back door 8, the occupant only needs to open / close the back door 8 and does not need to operate the tonneau cover 36. Therefore, the passenger of the vehicle 1 can easily take in and out the luggage through the rear opening 7 with respect to the luggage compartment 2.

  In addition, the tonneau cover 36 is constituted by a board, and the rear divided portion 37b and the rear cover 38 of the front cover 37 are moved by the interlocking wire 52, the drawing wire 62, and the torsion coil spring 43. The tonneau cover device 35 can be configured at a low cost. In particular, it is advantageous in that an expensive winding device can be eliminated as compared with a method of winding a cloth tonneau cover in conjunction with the opening operation of the back door 8.

  In the above embodiment, the front cover 37 is divided into the front divided portion 37a and the rear divided portion 37b, and only the rear divided portion 37b is moved in conjunction with the opening / closing operation of the back door 8. However, the entire front cover 37 may be moved without being divided (for example, rotated about an axis extending in the vehicle width direction passing through the front end of the front cover 37). Alternatively, instead of the front cover 37 of the above-described embodiment, a cloth front cover is provided, and a winding device for winding the front cover is provided on the front side of the front cover, and in conjunction with the opening operation of the back door 8. You may make it wind up this front side cover with a winding device, raising the rear end of this front side cover.

  Moreover, in the said embodiment, although the interlocking mechanism 51 and the rear side cover moving mechanism 61 were each comprised with the wire, you may comprise with a link mechanism, a gear, etc. instead of a wire.

  The present invention is useful for a tonneau cover device for a vehicle including a tonneau cover provided in a luggage compartment at the rear of the vehicle.
