An auxiliary compression spring 44 is provided in parallel with the compression coil spring 43, and the rear end of the auxiliary compression spring 44 is fixed to the back wall 31 by, for example, brazing. A closing plate 45 is fixed to the distal end of the auxiliary compression spring 44 by, for example, brazing. The closing plate 45 is provided with the supporting rod 40 and the side wall 30S.
It has a thickness that can move along the gap between
A tapered surface 46 corresponding to the tapered surface 42B of the support rod 40 is formed.

Next, the operation of the assist grip according to the present embodiment will be described. Assist grip body 10
Is normally in a prone position with respect to the indoor wall 14, as shown in FIG. This prevents the assist grip body 10 from projecting from the indoor wall 14 and obstructing it.

If the use of an assist grip is desired, proceed as follows. That is, by pressing the assist grip body 10 (see FIG. 3) in the prone position against the indoor wall 14, the supporting rod 40 is pushed by the assist grip body 10 toward the back of the recess 50. Then, the tapered surface 42B of the locking projection 42 provided on the supporting rod 40 comes into sliding contact with the opening edge of the locking hole 34, and the supporting rod 40 moves upward in FIG. Tapered surface 42B of portion 42 and closing plate 4
5 comes into contact with the tapered surface 46.

Here, since the auxiliary compression spring 44 on the back side of the closing plate 45 is already in an elastically compressed state and is not easily deformed, when the supporting rod 40 is further pushed to the back side of the recess 50. However, the closing plate 45 cannot move to the inner side of the recess 50, and the two tapered surfaces 42B and 46 come into sliding contact with each other, and the locking projection 42 rides on the upper surface of the closing plate 45. Then, both tapered surfaces 42
The contact between B and 46 is released, and the closing plate 45 is moved forward of the recess 50 by the elastic force of the auxiliary compression spring 44, and the locking hole 34 is closed by the closing plate 45.

Here, when the operation of pushing the assist grip body 10 toward the indoor wall 14 is stopped, the urging force of the compression coil spring 43 causes the support rod 40 to open the opening 3 of the recess 50.
It is pushed to two sides. At this time, since the locking hole 34 is closed by the closing plate 45, the locking projection 42 does not lock in the locking hole 34, and the supporting rod 40 is connected to the compression coil spring 4.
With the biasing force of 3, the arm 50 moves toward the opening 32 side of the recess 50, protrudes from the opening 32, and pushes up the assist grip body 10 from the interior wall 14. Thereby, the assist grip main body 10 is held in the gripped posture raised from the indoor wall 14, as shown in FIG.

Next, when the assist grip becomes unnecessary, the following is performed. That is, the assist grip body 10 in the gripping posture (see FIG. 4) is pressed against the indoor wall 14 side. Then, the locking projection 42 provided on the supporting rod 40 abuts on the closing plate 45 halfway. Here, since the auxiliary compression spring 44 connected to the closing plate 45 is in an extended state, the closing plate 45 is easily compressed and deformed when the closing plate 45 is pressed. 4
The closing plate 45 moves to the far side of the recess 50 without climbing on the fifth step 5. Then, the locking hole 34 is opened, and the locking projection 42 enters therein. When the hand is released from the recess 50, the supporting rod 40 is pushed back by the compression coil spring 43, and the front locking surface 42A of the locking projection 42 and the inner surface of the locking hole 34 are locked. Then, the supporting rod 40 is the recess 5
The assist grip main body 10 is held in the prone position by the urging force of the torsion coil spring 25 while being held in the retracted state within 0.

As described above, according to the assist grip of the present embodiment, the push lock mechanism in which the lock is released when pressed once and the lock is released when pressed again, is provided between the assist grip body 10 and the interior wall 14. In this manner, the assist grip body 10 can be held by switching to a desired posture between the prone posture and the grasped posture. Thus, for example, if necessary, the assist grip body 10 is held in the gripped posture, and the occupant can immediately grip the assist grip even in the case of a sudden impact during traveling.

<Other Embodiments> The present invention is not limited to the above embodiments. For example, the following embodiments are also included in the technical scope of the present invention.
In addition to the following, various changes can be made without departing from the scope of the invention. (1) As in the above-described embodiment, if the push rod 40 is pushed once, the push rod 40 waits in the recess 50, and if it is pushed again, the push rod 40 projects from the recess 50. The so-called “push lock mechanism” may be other than the above embodiment. For example, each time the strut rod is pressed, such as one provided for insertion and removal of a ball-point pen core, the strut rod rotates by a predetermined angle, whereby the strut rod and its strut are rotated. The locking position of the recess accommodating the rod with the inner wall may be changed, thereby constituting the push lock mechanism.
