A plate-like pin-side flange 12 protruding outward in the radial direction of the shaft portion 11 is formed at the proximal end of the shaft portion 11. The pin-side flange 12 has a quadrangular outer shape, and an edge wall 13 that protrudes downward and extends along the edge is formed at the edge. On the upper surface of the pin side flange 12 on the shaft portion 11 side, a garnish coupling portion 15 projects upward. The garnish coupling portion 15 has a quadrangular columnar neck portion 16 projecting from the pin-side flange 12 and an enlarged head portion 17 provided at the tip of the neck portion 16 and projecting from the neck portion 16 in a direction perpendicular to the axis A.

  The shaft portion 11 has an inner hole 21 that opens to the distal end or the base end of the shaft portion 11 and is formed hollow. Two first elastic claws 22 are formed on the outer peripheral surface of the shaft portion 11 at symmetrical positions with the axis A as the center. The first elastic claw 22 is formed by a U-shaped slit 23 that passes through the inner surface 21 from the outer surface of the shaft portion 11 and extends upward (defined). And a claw portion 25 protruding from the outer surface. The cantilever piece 24 has flexibility and is formed to be tiltable toward the axis A side of the shaft portion 11. In other words, the cantilever piece 24 is formed to be tiltable into the inner hole 21. The claw portion 25 has an inclined surface 27 that protrudes outward from the shaft portion 11 as it progresses upward, a check surface 28 that faces the upper end of the inclined surface 27, and an upward-facing check surface 28. And a stepped portion 29 that forms a downwardly facing surface.

  As shown in FIG. 3, a concave portion 31 extending in the direction of the axis A is recessed in the outer peripheral surface of the shaft portion 11 and on the base end side portion of the portion where the first elastic claws 22 are provided. It is installed. As shown in FIGS. 2 and 3, on the outer peripheral surface of the shaft portion 11, two guide convex portions 32 extending along the axis A from the tip end to the base end of the shaft portion 11 are centered on the axis A. Projected at symmetrical positions.

  As shown in FIGS. 1, 4, and 5, the grommet 3 includes a cylindrical cylindrical portion 36 that is open at both ends extending in the vertical direction from a proximal end (upper end) to a distal end (lower end), and a proximal end of the cylindrical portion 36. And a rectangular plate-shaped grommet side flange 37 that protrudes outward from the cylindrical portion 36. A through hole 38 is formed in the cylindrical portion 36 and extends from the proximal end to the distal end. An annular boss 39 is provided on the upper surface of the grommet side flange 37 so as to surround the through hole 38.

  Two second elastic claws 41 are formed at symmetrical positions around the axis B at the base end side portion of the cylindrical portion 36. The second elastic claw 41 is formed by a U-shaped slit 42 penetrating from the outer surface of the cylindrical portion 36 to the through hole 38 and extending upward (defined). And a claw portion 45 projecting from the outer surface. The cantilever piece 44 has flexibility and is formed to be tiltable into the through hole 38 of the cylindrical portion 36. The claw portion 45 has an inclined surface 47 that protrudes outward from the cylindrical portion 36 as it progresses upward, and a check surface 48 that faces the upper end of the inclined surface 47 and faces upward.

  Engagement holes 51 penetrating from the outer peripheral surface of the cylindrical portion 36 to the through hole 38 are formed in the tip side portion of the portion where the second elastic claws 41 of the cylindrical portion 36 are provided. Two guide grooves 52 extending along the axis B from the base end to the tip are formed at symmetrical positions around the axis B on the inner peripheral surface of the cylindrical portion 36, that is, the wall surface of the through hole 38. Yes.

  The pin 2 and the grommet 3 are combined with each other before being bonded to the garnish 4 or the side sill 5 and take the form shown in FIGS. When the pin 2 is assembled to the grommet 3, an annular first seal member 61 that surrounds the shaft portion 11 is attached to the lower surface of the pin side flange 12, and an annular second seal that surrounds the cylindrical portion 36 to the lower surface of the grommet side flange 37. The seal member 62 is attached. In a state where the pin 2 and the grommet 3 are arranged coaxially with each other, the distal end portion of the shaft portion 11 of the pin 2 is inserted into the proximal end side of the through hole 38 of the grommet 3. At this time, the guide convex portion 32 of the pin 2 is fitted into the guide groove 52 of the grommet 3, and the relative rotational positions around the axes A and B of the pin 2 and the grommet 3 are determined. When the shaft portion 11 is inserted into the through hole 38, the claw portion 25 of the first elastic claw 22 hits the hole wall of the through hole 38 at the step portion 29 and the inclined surface 27, and the cantilever piece 24 is By tilting inward, the first elastic claw 22 can enter the through hole 38. When the insertion of the shaft portion 11 into the through hole 38 proceeds, the first elastic claw 22 reaches the engagement hole 51 and the claw portion 25 enters the engagement hole 51 as shown in FIGS. 1 and 6. The cantilever piece 24 returns to the initial state by the restoring force. In this state, when the check surface 28 of the claw portion 25 abuts against the upper edge of the hole wall of the engagement hole 51, the pin 2 is prevented from moving upward with respect to the through hole 38, that is, moving in the removal direction. . Further, when the step portion 29 of the claw portion 25 abuts against the lower edge of the hole wall of the engagement hole 51, the downward movement of the pin 2 with respect to the through hole 38 is prevented. Thus, the state in which the first elastic claw 22 is disposed in the engagement hole 51 is referred to as a first state (initial state) of the garnish clip 1, and the position of the pin 2 with respect to the grommet 3 is referred to as a first position.

  After setting the garnish clip 1 to the first state, the garnish clip 1 is coupled to the garnish 4 and the side sill 5. The garnish 4 has a coupling seat 71 coupled to the garnish coupling portion 15 of the pin 2 on the back surface thereof. The coupling seat 71 includes a pair of plate-like walls 72 projecting from the back surface of the garnish 4, a plate-like beam 73 that connects the protruding end edges of the pair of walls 72, and a slit 74 formed in the beam 73. And have. The slit 74 penetrates the beam 73, and one end is open to the side of the beam 73. The pin 2 and the garnish 4 are coupled by inserting the neck portion 16 of the garnish coupling portion 15 into the slit 74 and hooking the enlarged head portion 17 on the hole edge of the slit 74. At this time, it is preferable that the beam 73 is held between the enlarged head 17 and the pin side flange 12 without rattling.

  The side sill 5 is made of a steel plate, and a mounting hole 76 that is a through hole is formed in the steel plate portion. In the present embodiment, the attachment hole 76 has a quadrangular cross section as shown in FIG. In other embodiments, the attachment hole 76 may be a circular hole. The cylindrical portion 36 of the grommet 3 is inserted into the mounting hole 76. At this time, the second elastic claw 41 of the grommet 3 is disposed so as to correspond to the linear portion (side) of the attachment hole 76, and the claw portion 45 contacts and presses the hole edge of the attachment hole 76. When the second elastic claw 41 is pressed against the hole edge of the attachment hole 76, the cantilever piece 44 tilts inward of the cylindrical portion 36, and the claw portion 45 passes through the attachment hole 76. At this time, since the back surface (inner surface) of the cantilever piece 44 faces the concave portion 31 of the shaft portion 11 of the pin 2, the cantilever piece 44 can enter the concave portion 31 by tilting. After the claw portion 45 passes through the mounting hole 76, the cantilever piece 44 returns to the initial position by the restoring force, and the claw portion 45 engages with the hole edge of the mounting hole 76 on the check surface 48, so that the grommet 3 The upward movement (extraction direction) with respect to the side sill 5 is restricted. At this time, the second seal member 62 is sandwiched between the grommet side flange 37 and the hole edge portion of the attachment hole 76 of the side sill 5 to seal between the two members. As described above, as shown in FIG. 7, the garnish clip 1 joins the garnish 4 and the side sill 5 in a state of being separated from each other. This state is called a temporary connection state.

  When the garnish 4 is pushed into the side sill 5 in the temporary connection state shown in FIG. 7, the garnish 4 as shown in FIG. 8 shifts to a connection completion state in which the garnish 4 is arranged close to the surface of the side sill 5. When the transition from the temporarily connected state to the completed state is completed, the pin 2 of the garnish clip 1 is further inserted into the grommet 3 from the first position, and the first elastic claw 22 is externally provided from the lower end opening of the through hole 38. To the second position protruding. In the second position, the check surface 28 of the first elastic claw 22 is caught by the lower end surface (second engagement portion) 78 of the cylindrical portion 36, and the upward movement (extraction direction) of the pin 2 with respect to the grommet 3 is restricted. The The state when the pin 2 is in the second position with respect to the grommet 3 is referred to as the second state of the garnish clip 1. In the second state, the first seal member 61 is sandwiched between the pin-side flange 12 and the boss 39, and the two members are sealed.

  The insertion force required to move the pin 2 relative to the grommet 3 from the first position to the second position (insertion force for pushing the shaft portion 11 into the through hole 38), that is, all the first elastic claws 22 are engaged. Resistance force generated by the first elastic claw 22 from the inside of the joint hole 51 to the lower end surface 78 of the through hole 38 (the cantilever 24 of the first elastic claw 22 resists the elastic force and The force required to tilt (deform) toward the direction and the frictional force generated on the contact surface between the claw portion 25 and the through-hole 38) are defined as the first resistance force. Further, an insertion force necessary for inserting the cylindrical portion 36 of the grommet 3 into the attachment hole 76, that is, a resistance force generated by the second elastic claws 41 when all the second elastic claws 41 pass through the attachment holes 76. (The force required to tilt (deform) the cantilever piece 44 of the second elastic claw 41 inward of the cylindrical portion 36 against the elastic force and the contact surface between the claw portion 45 and the mounting hole 76) The generated friction force) is defined as a second resistance force. If it prescribes | regulates in this way, in this embodiment, the shape of the 1st elastic nail | claw 22 and the 2nd elastic nail | claw 41 is set so that a 1st resistance force may become larger than a 2nd resistance force. The first resistance force and the second resistance force are the length and thickness of the cantilever pieces 24 and 44, the position and the protruding length of the claw portions 25 and 45 with respect to the cantilever pieces 24 and 44, and the inclination of the inclined surfaces 27 and 47. It can be adjusted by changing the surface shape, the protruding length and inclination of the step 29, the material of the pin 2 and the grommet 3, and the like.

  Since the first resistance force is larger than the second resistance force, the garnish clip 1 according to the present embodiment unintentionally shifts from the first state to the second state when the grommet 3 is inserted into the mounting hole 76. It is prevented. Therefore, the operation of attaching the garnish clip 1 to the side sill 5 is easy.

  Since the garnish clip 1 according to the present embodiment can maintain the garnish 4 in a temporarily bonded state separated from the surface of the side sill 5, the side sill 5 and the garnish 4 are simultaneously applied by spraying in this state, and the coating is completed. After that, the garnish 4 can be shifted to the bonding completion state in which the garnish 4 is disposed on the surface of the side sill 5. By performing the coating in the temporarily bonded state, the coating can be applied to the portion covered with the garnish 4 of the side sill 5 in the combined completed state, so that the coating can be applied to the side sill 5 and the garnish 4 in the combined completed state. It is possible to reliably paint the boundary portion. In addition, since the edge wall 13 is provided at the edge of the pin side flange 12 and the first seal member 61 is disposed on the lower surface of the pin side flange 12, that is, the portion surrounded by the edge wall 13, the paint is applied to the first seal member 61. It is difficult to adhere, and the first seal member 61 is prevented from being deteriorated.

  Next, a method for removing the garnish 4 and the garnish clip 1 will be described. First, the garnish 4 is slid with respect to the garnish clip 1 in the diameter direction of axes A and B, the neck 16 is detached from the slit 74, and the garnish 4 is separated from the garnish clip 1. Next, the pin 2 is gripped and rotated around the axes A and B with respect to the side sill 5, and the second elastic claws 41 are made to correspond to the corners of the mounting holes 76 (see the two-dot chain line in FIG. 9). Thereby, the catch (overlap when viewed from above) between the second elastic claw 41 and the hole edge of the attachment hole 76 is reduced. Thereafter, when the pin 2 is pulled upward with respect to the side sill 5, the second elastic claw 41 tilts inward of the cylindrical portion 36, and the grommet 3 is extracted from the mounting hole 76. Since the cantilever piece 44 of the second elastic claw 41 faces the recess 31 in the second state, the inward tilting of the cylindrical portion 36 is allowed.

  The garnish clip 1 according to the present embodiment is configured so that the pin 2 is engaged by engagement between the guide convex portion 32 and the guide groove 52 and engagement between the edge wall 13 of the pin side flange 12 and the edge portion of the grommet side flange 37. Since the rotation around the axes A and B with respect to the grommet 3 is restricted, the grommet 3 rotates with the rotation of the pin 2.

  Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. In the present embodiment, in the second state, the first elastic claw 22 is configured to engage with the lower end surface 78 of the cylindrical portion 36, but a hole similar to the engaging hole 51 is formed on the side surface of the cylindrical portion 36, You may make it engage the 1st elastic nail | claw 22 with this hole. In the embodiment, the number of the first and second elastic claws 22 and 41 is two. However, the number of the elastic claws 22 and 44 may be at least one.
