In contrast, the grip cover 60 is attached. Each of the fixed claws 46 is configured to be elastically flexible and deformable in the plate thickness direction, and when inserted through the fixed hole 26, the fixed claw 46 is bent and deformed, and after elastic insertion, It is possible to lock the hole edge of the fixed hole 26 from the outside of the passenger compartment.

  In the present embodiment, among the side wall portions constituting the grip cover 60, the lower end portion of the side wall portion 63 disposed on the rear side of the vehicle has a substantially L-shaped locking piece 65 (see FIG. 5). (Locking part) is erected. In other words, the locking piece 65 is provided at the lower end portion of the grip cover 60 and at the location that becomes the vehicle rear end portion.

  As described above, the lower portion of the door grip 40 is fitted into the lower grip mounting portion 22 (mounting recess) in the trim board 12. As shown in FIG. 4, a through hole 27 </ b> A penetrating in the vehicle front-rear direction is formed in the side wall portion 27 arranged on the vehicle rear side among the wall portions constituting the inner surface of the lower grip attachment portion 22. .

  The through hole 27A is provided at a location corresponding to the locking piece 65, and has a substantially square shape as shown in FIG. A situation in which the grip cover 60 is lifted with respect to the trim board 12 (a situation in which the peripheral end of the grip cover 60 is displaced away from the trim board 12) because the locking piece 65 is locked to the edge of the through hole 27A. ) Is prevented.

  Next, the configuration of the locking piece 65 will be described in detail. On the back surface of the grip cover 60, as shown in FIG. 6, a pedestal having a substantially L shape is formed by connecting a main wall portion 64 (a wall portion mainly constituting the design surface of the grip cover 60) and the side wall portion 63. A portion 66 is provided. The locking piece 65 is formed on a surface 66 </ b> A outside the passenger compartment in the pedestal portion 66 (surface on the interior material main body side in the grip cover).

  As shown in FIG. 6, the locking piece 65 includes a first extending portion 67 that extends from the outer surface 66 </ b> A of the pedestal portion 66 toward the trim board 12, and a tip of the first extending portion 67. And a second extending portion 68 extending in a shape bent toward the rear side of the vehicle. As shown in FIG. 6, the first extending portion 67 and the second extending portion 68 constitute a substantially L-shaped piece. The second extending portion 68 is inserted from the vehicle front side into the through hole 27A, and is locked to the hole edge portion 28 of the through hole 27A from the outside of the vehicle compartment.

  An inclined wall portion 69 that is inclined with respect to the extending direction of the second extending portion 68 is extended from the distal end portion of the second extending portion 68. A surface on the rear side of the vehicle in the inclined wall portion 69 is an extended surface 69 </ b> A that extends toward the outside of the passenger compartment as it goes rearward of the vehicle. In other words, the extending surface 69A extends in the form toward the center R1 of the through hole 27A as it goes in the insertion direction of the second extending portion 68 with respect to the through hole 27A. In addition, in FIG. 6, the insertion direction of the 2nd extension part 68 with respect to 27 A of through-holes is shown by the arrow line P1.

  The locking piece 65 has a rib 70 (reinforcing rib) for increasing the rigidity of the locking piece 65. The rib 70 is formed on the surface of the locking piece 65 opposite to the contact surface with respect to the trim board 12. The rib 70 extends across (over) both the first extending portion 67 and the second extending portion 68. One end of the rib 70 is connected to the inclined wall 69, and the other end of the rib 70 is connected to the pedestal 66.

  By providing such a rib 70, it is possible to increase the rigidity of the locking piece 65, and to prevent the rib 70 from being bent. In this embodiment, as shown in FIG. 5, two ribs 70 are formed on the locking piece 65, and the two ribs 70 are arranged in parallel along the width direction of the locking piece 65.

  As shown in FIG. 4, at the opening end of the lower grip attachment portion 22 opened to the vehicle interior side, a portion in the vicinity of the hole edge portion 28 of the through hole 27 </ b> A is a stepped portion 29 that is low outside the vehicle interior. As shown in FIGS. 6 and 7, the step portion 29 is configured to be fitted with a peripheral end portion of the grip cover 60. By fitting the peripheral end portion of the grip cover 60 to the stepped portion 29, the design of the parting portion (boundary portion) between the grip cover 60 and the trim board 12 can be enhanced.

  The hole edge portion 28 is constituted by a part of the step portion 29. For this reason, as shown in FIG. 6, the end surface of the hole edge portion 28 is arranged slightly inside the peripheral end (side wall portion 63) of the grip cover 60. Correspondingly, the locking piece 65 is arranged slightly inside the peripheral end (side wall portion 63) of the grip cover 60 and can be locked to the hole edge portion 28. Yes.

  Next, an operation when the grip cover 60 is attached to the trim board 12 will be described. The worker who performs the attachment first locks the locking piece 65 of the grip cover 60 with respect to the hole edge portion 28 of the through hole 27A. Specifically, the second extending portion 68 of the locking piece 65 is inserted into the through hole 27A from the vehicle compartment front side.

  When the second extending portion 68 is inserted through the through hole 27A, the extending surface 69A of the locking piece 65 is brought into contact with the hole edge portion 28 as shown in FIG. As a result, the extended surface 69A of the locking piece 65 slides with respect to the hole edge portion 28, so that the second extended portion 68 is inserted into the through hole 27A and goes toward the center of the through hole 27A. To be guided. That is, the extended surface 69A is a guide surface for guiding the insertion of the locking piece 65 (second extended portion 68) into the through hole 27A.

  Thereby, the operation | work which inserts the 2nd extension part 68 in 27 A of through-holes can be performed easily. Then, by inserting the second extending portion 68 through the through hole 27A, the second extending portion 68 is locked to the hole edge portion 28 from the outside of the vehicle compartment.

  After the second extending portion 68 is inserted into the through hole 27A, the fixing claws 46 provided on the grip cover 60 are attached to the corresponding fixing holes 26, respectively. Thereby, the attachment of the grip cover 60 to the trim board 12 is completed.

  Next, the effect of this embodiment will be described. According to the present embodiment, the locking piece 65 provided at the peripheral end of the grip cover 60 is locked to the hole edge portion 28 of the through hole 27A from the outside of the passenger compartment. A situation in which the peripheral end portion is displaced toward the vehicle interior side can be suppressed. Thus, for example, even when the grip cover 60 is pulled toward the vehicle interior when the door grip 40 is used (for example, when the vehicle door is closed), as shown in FIG. The situation which a clearance gap produces between the peripheral edge part and the trim board 12 can be suppressed. As a result, it is possible to suppress a situation where the designability is lowered.

  The locking piece 65 includes a first extending portion 67 extending from the outer surface 66 </ b> A of the grip cover 60 toward the trim board 12, and a first extending portion from the tip of the first extending portion 67. A second extending portion 68 that extends in a bent manner with respect to the portion 67 and is locked to the hole edge portion 28 of the through hole 27A from the outside of the passenger compartment, and a first extending portion 67 and a second extending portion. And a rib 70 extending across both of the portions 68.

  The second extending portion 68 is bent with respect to the first extending portion 67, and the locking piece 65 is formed in an approximately L shape, so that the second extending portion 68 is made to extend toward the hole edge portion 28 of the through hole 27A. The installation part 68 can be locked more reliably. And the rigidity of the locking piece 65 can be made high by providing the rib 70 extended ranging over both the 1st extension part 67 and the 2nd extension part 68. FIG. As a result, it is possible to more reliably prevent a situation in which the locking with respect to the hole edge portion 28 is released due to the locking piece 65 being bent.

  The above effect will be described in detail with reference to FIGS. 9 to 11 are diagrams showing comparative examples of the grip cover 60. FIG. In this comparative example, as shown in FIG. 9, instead of the locking piece 65, the fixing claw 6 is locked to the hole edge portion 28 of the through hole 27A.

  Since such a fixed claw 6 is generally premised on being bent and deformed at the time of attachment, it is configured to be able to bend and deform in the plate thickness direction. For this reason, in the configuration in which the fixed claw 6 is locked to the hole edge portion 28 of the through hole 27A, when the occupant pulls the grip cover 60 toward the vehicle interior side, the grip cover 60 is twisted and the fixed claw 6 is Then, it is pulled away from the trim board 12. As a result, the fixed claw 6 is bent and deformed as shown in FIG. As a result, there is a concern that the locking of the fixed claw 6 with respect to the hole edge portion 28 is released. As a result, as shown in FIG. 11, as a result of the peripheral end portion of the grip cover 60 being displaced toward the vehicle interior side, a gap S <b> 2 is generated between the grip cover 60 and the trim board 12, thereby reducing the design.

  In this respect, the locking piece 65 of the present embodiment is not based on the premise that the locking piece 65 bends and deforms like the fixed claw 6, so that it is possible to suppress a situation where the rigidity is high and the deformation is deformed. Moreover, since the latching piece 65 is provided with the rib 70, the rigidity is higher. As a result, even when the grip cover 60 is pulled toward the vehicle interior side, the engagement of the engagement piece 65 with respect to the hole edge portion 28 is not released, and the peripheral end portion of the grip cover 60 remains in the vehicle interior. The situation of being displaced inward can be more reliably suppressed.

  Further, the inclined wall portion 69 (the tip end portion of the locking piece) of the locking piece 65 is extended in a form toward the center R1 of the through hole 27A as it goes in the insertion direction of the second extending portion 68 with respect to the through hole 27A. It has an extended surface 69A.

  When the locking piece 65 is inserted through the through hole 27A, the extending surface 69A is brought into contact with the hole edge 28 of the through hole 27A. As a result, the locking piece 65 is guided along the extending direction of the extending surface 69A (the direction toward the center of the through-hole as it goes in the insertion direction of the locking portion), so that the second extending portion 68 can be easily formed. Can be inserted through the through hole 27A.

  Moreover, in the grip cover 60 of this embodiment, the locking piece 65 is provided in the location used as a vehicle rear end part and a lower end part. When the occupant grips the grip portion 40A of the door grip 40 (intermediate portion in the longitudinal direction, see FIG. 1) and closes the vehicle door to the vehicle interior side, the door grip 40 has an axis along the longitudinal direction. The load acts in the direction of twisting around the center. Specifically, a load acts in a direction in which a peripheral end portion on the vehicle rear side of the peripheral end portion of the grip cover 60 is displaced toward the vehicle interior side.

  Here, the rear end portion and the lower end portion of the vehicle in the grip cover 60 are the farthest portions from the grip portion 40A in the door grip 40, and therefore are particularly easily deformed when the door grip 40 is twisted. That is, in the present embodiment, when the vehicle door is closed using the grip cover 60, the locking piece 65 is provided at a location that is particularly easily deformed (location at the rear end and the lower end of the vehicle). Deformation can be effectively suppressed.
