FIG. 4 is a front view of the first leg wheel 14, the main guide rail 16, the second leg wheel 15, and the support plate 17 of the penetrating hood device 10 shown in FIG. 3 as viewed from the vehicle longitudinal direction. FIG. 5 is a plan view of the roller unit 19 and the sub guide rail 20 of the penetrating hood device 10 shown in FIG. FIG. 6 is a cross-sectional view of the roller unit 19 and the sub guide rail 20 shown in FIG. 5 as viewed from the longitudinal direction of the vehicle. As shown in FIG. 4, the first wheel 14 is unevenly fitted to the main guide rail 16 so as not to be displaced relative to the main guide rail 16 in the vehicle width direction, and is mounted on the main guide rail 16. It is configured to be able to roll in the longitudinal direction of the vehicle. The first leg ring 14 has a bobbin shape and has an annular recess 14a for guiding. The first leg wheel 14 is attached to the through box 11 so as to be rotatable around the vertical axis.

The main guide rail 16 has a convex portion 16a and a pair of derailment prevention wall portions 16b. The convex portion 16a extends in the longitudinal direction of the vehicle and supports the first leg wheel 14 from below in a state where the concave portion 14a of the first leg wheel 14 is fitted. The pair of derailment prevention wall portions 16b face the first wheel 14 from both sides in the vehicle width direction with a gap in the vehicle width direction from the first wheel 14. That is, the first leg wheel 14 is guided in the vehicle longitudinal direction by the convex portion 16a of the main guide rail 16, and the derailment prevention wall portion 16b of the main guide rail 16 derails the first leg wheel 14 from the convex portion 16a. Is prevented.

Unlike the first leg ring 14, the second leg ring 15 does not have a recess for guiding and is a leg ring having a general shape. The second leg wheel 15 is attached to the through box 11 so as to be rotatable around the vertical axis. The support plate 17 is a flat plate having no convex portion for guidance. That is, the second leg ring 15 is not guided by the support plate 17, and the second leg wheel 15 simply rolls on the support plate 17.

As shown in FIGS. 5 and 6, the roller unit 19 is attached to the through box 11 via the rear bracket 18. The roller unit 19 has a vertical roller 31, a horizontal roller 32, a retainer 33, and a shaft 34. The vertical roller 31 is rotatable around an axis extending in the vehicle width direction. The vertical roller 31 is arranged at the center of the roller unit 19 in the longitudinal direction of the vehicle. The horizontal roller 32 is rotatable around an axis extending in the vertical direction. The horizontal rollers 32 are arranged on both sides of the vertical rollers 31 in the longitudinal direction of the vehicle. The retainer 33 holds the vertical roller 31 and the horizontal roller 32. The upper end of the shaft 34 is fixed to the rear bracket 18, and the lower end of the shaft 34 is attached to the retainer 33. The shaft 34 is attached to the retainer 33 so as to be rotatable with respect to the vertical roller 31 and the horizontal roller 32 around an axis extending in the vertical direction. Further, the shaft 34 is attached to the retainer 33 so as to be rotatable with respect to the vertical roller 31 and the horizontal roller 32 around the axis extending in the vehicle width direction. That is, the roller unit 19 is provided so as to be angularly displaceable with respect to the through box 11.

The sub-guide rail 20 extends in the longitudinal direction of the vehicle and guides the vertical roller 31 and the horizontal roller 32 of the roller unit 19 in the longitudinal direction of the vehicle. The sub guide rail 20 is fixed to the floor surface 7 via the rubber plate 35. The auxiliary guide rail 20 has an upper plate portion 20a and a lower plate portion 20b that sandwich the vertical roller 31 from both sides in the vertical direction, and a pair of side plate portions 20c that sandwich the horizontal roller 32 from both sides in the vehicle width direction. Is formed with a slit 20d extending in the longitudinal direction of the vehicle through which the shaft 34 is inserted.

According to the configurations shown in FIGS. 4 to 6, the first leg wheel 14 is guided in the vehicle longitudinal direction by the main guide rail 16, and the roller unit 19 is guided in the vehicle longitudinal direction by the sub guide rail 20. It is possible to prevent the penetration box 11 from being undesirably displaced with respect to 2. Moreover, since the second leg wheel 15 is not guided by the guide rail and the roller unit 19 is provided so as to be angularly displaced with respect to the through box 11, the positional relationship between the through box 11 and the vehicle body 2 is changed. It is possible to give some degree of freedom, and even if the vehicle body 2 is twisted, the stress generated in the first leg wheel 14 and the roller unit 19 can be suppressed.

Specifically, the shaft 34 rotates about the vertical axis with respect to the vertical roller 31 and the horizontal roller 32 while restricting the displacement of the roller unit 19 in the vehicle width direction by the pair of side plate portions 20c of the sub guide rail 20. Since the angular displacement of the through box 11 with respect to the sub guide rail 20 is allowed, the stress generated in the roller unit 19 can be suppressed. In particular, when the through box 11 is moved in the longitudinal direction of the vehicle by the actuator 21, resistance is generated in the first wheel 14 due to foreign matter being caught between the first wheel 14 and the main guide rail 16. , The through box 11 may generate a force that causes angular displacement when viewed from above, but even in such a case, the shaft 34 rotates about the vertical axis with respect to the vertical roller 31 and the horizontal roller 32. Since it is possible, the stress generated in the roller unit 19 can be suppressed.

Further, while the vertical displacement of the roller unit 19 is regulated by the upper plate portion 20a and the lower plate portion 20b of the sub guide rail 20, the shaft 34 swings back and forth with respect to the vertical roller 31 and the horizontal roller 32, so that the sub guide rail 20 is subordinated. Since the through box 11 is allowed to swing back and forth with respect to the guide rail 20, the stress generated in the roller unit 19 can be suppressed.

Further, since the roller unit 19 is arranged between the first wheel 14 and the second wheel 15 in the vehicle width direction, it is not necessary to provide a wasted space in the vehicle width direction for the roller unit 19. Space efficiency is improved. Further, since the roller unit 19 is located behind the through box 11, the roller unit 19 can be visually recognized without being disturbed by the through box 11, and the roller unit 19 can be easily assembled to the sub guide rail 20. ..

FIG. 7 is a side view of the actuator 21 and the joint mechanism 23 of the penetrating hood device 10 shown in FIG. 2 as viewed from the vehicle width direction. FIG. 8 is a front view of the actuator 21 and the joint mechanism 23 shown in FIG. 7 as viewed from the longitudinal direction of the vehicle. As shown in FIG. 7, the casing 21a of the actuator 21 is supported by a support base 22 fixed to the floor surface 7 of the vehicle body 2. The support base 22 supports a portion of the casing 21a on the front side of the center in the longitudinal direction. The support base 22 rotatably supports the casing 21a around an axis extending in the vehicle width direction. According to such a configuration, the actuator 21 is allowed to swing back and forth while keeping the forward / backward direction of the rod 21b of the actuator 21 in the longitudinal direction of the vehicle. Stress can be suppressed.

As shown in FIGS. 7 and 8, the joint mechanism 23 includes a first mounting member 41, a second mounting member 42, a swing member 43, a roller 44, and a shaft 45. The first mounting member 41 is fixed to the front end portion of the rod 21b of the actuator 21. A central portion of the swing member 43 is attached to the front end portion of the first attachment member 41 so that the swing member 43 can be angularly displaced. The rocking member 43 is attached to the rod 21b so as to be rotatable around an axis extending in the vertical direction and rotatably around an axis extending in the longitudinal direction of the vehicle. Since the swing member 43 is rotatable with respect to the rod 21b, the second mounting member 42 has an angle with respect to the first mounting member 41 around the axis extending in the vertical direction and around the axis extending in the longitudinal direction of the vehicle. It can be displaced.

The rocking member 43 extends in the vehicle width direction, and has roller accommodating portions 43a at both ends in the longitudinal direction (both ends in the vehicle width direction). The roller 44 is attached to the swing member 43 via a shaft 45 extending in the vertical direction while being housed in the roller accommodating portion 43a, and is rotatable around an axis extending in the vertical direction. The second mounting member 42 is fixed to the front portion of the lower surface of the through box 11. The second mounting member 42 has a cavity portion 42a that accommodates the roller 44 so as to be vertically displaceable and tiltable. The vertical dimension of the cavity portion 42a is larger than the vertical dimension of the roller 44. By tilting the roller 44 back and forth in the cavity portion 42a, the second mounting member 42 can be angularly displaced around the axis extending in the vehicle width direction with respect to the first mounting member 41. Further, by tilting the roller 44 to the left and right in the cavity portion 42a, the second mounting member 42 can be angularly displaced with respect to the first mounting member 41 around an axis extending in the longitudinal direction of the vehicle.

As described above, since the joint mechanism 23 is configured to be angularly displaceable, it is possible to give some degree of freedom to the positional relationship between the through box 11 and the actuator 21, and the vehicle body 2 is twisted. Even so, the stress generated in the joint mechanism 23 can be suppressed. Therefore, the through box 11 can be smoothly moved by the actuator 21 regardless of the vehicle body condition.

FIG. 9 is a side view of the penetrating hood device 10 shown in FIG. 1 as viewed from the vehicle width direction in the state of being used. FIG. 10 is a plan view of the penetrating hood device 10 shown in FIG. As shown in FIGS. 9 and 10, when the plug door 5 (see FIG. 1) is opened and the actuator 21 is driven to extend the rod 21b, the first leg wheel 14 and the roller unit 19 move into the main guide rail 16 and the sub guide rail. While being guided by 20, the first wheel 14 and the second wheel 15 roll on the main guide rail 16 and the support plate 17, respectively, and the through box 11 projects from the through port 4a to the outside of the vehicle body 2 and is used. To reach. After moving the penetrating box 11 to the used position, the penetrating hood 13 is extended in the longitudinal direction of the vehicle and fixed to the penetrating box 11'of another leading vehicle 1'which is a connection partner.

Since the penetration box 11 is moved in the longitudinal direction of the vehicle by the actuator 21, the penetration box 11 can be easily and accurately operated between the storage position (FIG. 1) and the use position (FIG. 9). Further, when the through box 11 is in the used position, the seal member 12 is sandwiched between the flange portion 11a of the through box 11 and the stopper portion 6 of the vehicle body 2 in the vehicle longitudinal direction. By sandwiching the seal member 12 between the flange portion 11a and the stopper portion 6 in this way, it is possible to prevent the through box 11 from undesirably coming out of the through opening 4a, and to seal the entire seal member 12. Pressure can be applied appropriately.

Further, when the through box 11 is in the used position, the plurality of pin portions 11b of the through box 11 are inserted into the plurality of positioning holes 6a of the stopper portion 6, respectively. According to this, when the through box 11 is in the used position, the through box 11 is prevented from being displaced relative to the vehicle body 2 in the direction orthogonal to the longitudinal direction of the vehicle, and sliding friction is generated in the seal member 12. Can be prevented.

Further, when the through box 11 is in the used position, the operation of the actuator 21 is fixed so that the actuator 21 supports the lower part of the through box 11, so that the actuator 21 applies a sealing pressure to the sealing member 12. Can also serve as. Therefore, the work of moving the through box 11 to the storage position / use position can be easily and accurately performed, and the sealing property between the through box 11 and the vehicle body 2 can be maintained while suppressing an increase in the number of parts.

Further, when the detection unit 24d of the lock device 24 detects that the penetration box 11 is in the used position, the lock body 24b is operated by the drive unit 24c, and the lock body 24b moves the upper portion of the flange portion 11a of the penetration box 11 from the rear. Move to a supported lock position. A roller 24ba is provided at a portion of the lock body 24b that comes into contact with the flange portion 11a in order to prevent sliding between the lock body 24b and the flange portion 11a. When the penetrating box 11 is in the used position, the locking body 24b restricts the movement of the penetrating box 11 toward the rear, so that the penetrating box 11 keeps the sealing pressure applied to the sealing member 12.

As described above, even if an external force acts on the through box 11 due to running vibration, acceleration / deceleration, curved running, or the like when the through box 11 is in the used position, the actuator 21 and the lock device 24 allow the through box 11 to act. Is supported, so that water intrusion from between the through box 11 and the vehicle body 2 can be suitably prevented regardless of the traveling state. Further, when the through box 11 is in the used position, both the upper part and the lower part of the through box 11 are stably supported by the actuator 21 and the locking device 24, so that the through box 11 tilts forward or tilts forward with respect to the vehicle body 2. It is possible to prevent the sealing member 12 from tilting backward and becoming non-uniform in the sealing pressure.

Further, the seal member 12 is composed of a first seal member 12a and a second seal member 12b that is softer than the first seal member 12a, but the first seal member 12a is compared with the second seal member 12b. Since it is arranged near the portion of the flange portion 11a of the through box 11 that is pressed by the lock body 24b, even if the seal pressure is weakened in the portion of the first seal member 12a that is separated from the lock device 24, the second seal member 12a is located. The expansion of the seal member 12b can prevent the formation of a gap. Moreover, since the first seal member 12a, which is harder than the second seal member 12b, is provided at a position close to the lock device 24, the first seal member 12a acts as a stopper, and the soft second seal member 12b is compressed too much. Can be prevented.

The present invention is not limited to the above-described embodiment, and its configuration can be changed, added, or deleted. For example, the pin portion 11b may be provided in the stopper portion 6 of the vehicle body 2, and the positioning hole 6a may be provided in the flange portion 11a of the through box 11. The support plate 17 may be the floor plate itself, not a separate body from the floor plate forming the floor surface 7. The actuator 21 may be an electromagnetic motor or a hydraulic cylinder instead of the pneumatic cylinder, and the same applies to the drive unit 24c of the lock device 24. In the roller unit 19, the horizontal roller 32 may be arranged in the center of the roller unit 19, and a pair of vertical rollers 31 may be arranged on both sides of the horizontal roller 32 in the longitudinal direction of the vehicle.
