Bending reinforcement portions are provided on the elastic leg portions on both sides of the mounting clip by bending an extending portion extending laterally from the plate-like elastic leg portion, and the mounting clip is formed in the rectangular hole of the vehicle body. When inserted, it is configured such that the vicinity of the bending reinforcement portion of the elastic leg portion contacts the fixed portion of the vehicle body,
The bending reinforcing portion is provided so as to project the extending portion to the outside of the elastic leg portion on both sides of the elastic bulge portion in a front view of the elastic bulge portion of the mounting clip. Each of the extended portions is bent inward at a substantially right angle.

  According to the present invention, by providing the bending reinforcement portion, the cross-sectional area of the elastic leg portion is increased, and sufficient proof strength can be given to the repeated load. As a result, when the hinge body to which the mounting clip is attached is pushed into and fixed to the rectangular hole provided in the vehicle body, the vicinity of the bending reinforcement portion of the elastic leg portion of the mounting clip contacts the fixed portion of the vehicle body. Even when a repeated load is applied to the elastic leg portion, the elastic leg portion is reinforced by the bending reinforcing portion, and no crack is generated, and the attachment clip can be prevented from being damaged.

  In addition, since the elastic leg can be reinforced only by providing an extended portion on the elastic leg of the mounting clip and bending it, the reliability of the assist grip can be improved without increasing the manufacturing cost. .

  In addition, the bent reinforcing portion can be easily formed, and the bent reinforcing portion becomes an angle-shaped right-angle reinforcing structure, so that the contact portion of the elastic leg portion can be strongly reinforced.

  On the other hand, when the user releases his / her hand from the grip body 1 in the state of use of the assist grip, the grip body 1 receives the upward biasing force (clockwise in FIG. 3) from the other end 62 of the torsion coil spring 6 in the same direction. , And returns to the non-use state (solid line position in FIG. 3). At this time, the action of the oil damper 8 brakes the rotation of the grip body 1, and the grip body 1 is not used at low speed. It will return to the position of.

  When such an assist grip is used for a long period of time, a load is repeatedly applied to the elastic leg portion 51 of the mounting clip 5 fitted in the rectangular hole of the body panel B at the contact point with the body panel B. By providing the leg reinforcement 51 with the bending reinforcement portion 58, the elastic leg portion 51 retains sufficient resistance against repeated loads.

  That is, when the assist grip is used, the vicinity of the bending reinforcement portion of the elastic leg portion 51 of the mounting clip 5 contacts the edge of the rectangular hole of the body panel B. Although it is applied to the contact portion of the elastic leg portion 51 and the contact portion of the elastic leg portion 51 is likely to crack, the bending reinforcement portion 58 increases the cross-sectional area of the contact portion of the elastic leg portion 51 and is reinforced with a right-angle structure. As a result, cracks do not occur, damage to the mounting clip 5 can be prevented, and the durability and life of the assist grip can be greatly improved.
