15 may come off from the recesses 4 and 5 of the grip body 1.

[0007]

[Means for Solving the Problems] In the present invention, the screw insertion hole in the bottom wall of the recess provided at both ends of the U-shaped grip body made of synthetic resin has an upwardly or downwardly inclined shape. A bulge is formed that protrudes from the bulge and can be displaced by fastening the screw, and a bulge is formed on the side surface of the recess of the bulge, rising inward or tilting outward as the bulge is displaced. A plurality of hook parts protrudingly engageable with claws provided on the back surface of the lid.

[0008]

[Operation] To attach the assist grip to the vehicle body, overlap the end surfaces of both ends of the grip body with the mounting portion of the vehicle body, and insert the screw insertion holes formed in the bottom wall of the recess provided at both ends of the grip body. The grip body is attached to the vehicle body by aligning with the mounting holes in the vehicle body and fastening screws from these screw insertion holes to the mounting holes in the vehicle body. Then, as the screws are tightened, the bulging portion is displaced so as to overlap with the attachment portion of the vehicle body, and with this displacement, the plurality of hook portions rise inward or tilt outward. In this state, by attaching the lid to the opening of the recess, the claws provided on the back surface of the lid engage with the plurality of hooks. As a result, the recesses and screws of the grip body attached to the vehicle body are covered with the lid.

[0009] In the state attached to this vehicle body,
When an occupant puts their hand on the grip body and applies a high load, the grip body bends around the screw that is the connection point to the car body, but the high load pushes the bulge toward the attachment part of the car body. As a result, the hook portion tightens its engagement with the claw on the lid.
