It is possible to prevent the situation in which the guide groove 75 is disengaged from the rails 4, 46.

Further, since the shaft support portion of the first leg portion 1a is constituted by the support pin 29 and the torsion coil spring 31 is arranged in the spring accommodating portion 23 around the support pin 29, the torsion is prevented. One end of the coil spring 31 is the grip body 1
, And the other end is locked to the mounting seat 3, respectively, so that the grip body 1 can be rotationally biased from the use position to the storage position.

Further, the shaft support portion of the second leg portion 1b is connected to the support portion 50.
Since the viscous damper 73 including the spacer 52 and the viscous agent L is used, when the grip body 1 rotates between the use position and the storage position, the inside of the outer peripheral surface of the spacer 52 and the support portion 50 is reduced. Viscous agent L filled between the peripheral surfaces
As a result, viscous resistance is imparted, and the grip body 1 can be slowly rotated.

The appearance can be improved without appearing. Furthermore, even if a force is applied to the grip body in the rotation range of the grip body between the use position and the storage position,
The end portion of the shaft supporting portion can be locked and held in the support hole. Therefore, the external appearance can be improved while maintaining the reliability of the retractable assist grip.

Further, according to the invention of claim 2, since the shaft supporting portion of the leg portion is constituted by the support pin and the coil spring is arranged in the mounting seat around the support pin, the coil spring By locking one end to the grip body and the other end to the mounting seat, the grip body can be rotationally biased from the use position to the storage position.

Further, according to the invention of claim 3, the shaft supporting portion of the leg portion is integrally fixed to the mounting seat by being formed integrally or separately, and the inner cylinder rotating integrally with the grip body. Since the viscous agent filled between the outer cylinder and the inner cylinder is provided, when the grip body rotates between the use position and the storage position, the viscous agent imparts viscous resistance to slowly move the grip body. It can be rotated.
