The base portion 3'is pivotally attached by the shaft 4 between a and pivots in one direction to project the hook 5 from the storage chamber 2 (Figs. 1 and 4), and pivots in the opposite direction to rotate the storage chamber 2 in the opposite direction. Shown is a hook member housed therein (Figs. 2, 5), wherein the housing 1 and the hook member 3 are molded from plastic.

The base portion 3'of the hook member 3 has a sector shape slightly larger than a 1/4 arc centered on the shaft 4 and has an arc surface 6 concentric with the shaft 4.

Then, on the inner surface of the storage chamber, that is, on one or both of the side walls 2a in this case, there is provided a projection 7 whose tip is brought close to the circular arc surface 6 of the base of the hook member. The protrusion 7 is not limited to the side wall of the storage chamber, and may be provided on the inner wall 2b at the bottom of the depression. or,
The base of the hook member is concentric with the circular arc surface 5 and has a circular arc surface 6
An arcuate slit 8 having a slightly smaller radius of curvature is provided to make the surface layer portion of the arcuate surface 6 flexible.

In the first embodiment shown in FIGS. 1 to 3, a coil spring 12 is wound around a shaft 4, one end 12a of the coil spring 12 is abutted against a spring receiver 13 on the inner surface of the storage chamber from above, and the other end 12b thereof is a ridge 14 at the base of the hook member. From below, the coil spring 12 urges the hook member 3 to rotate in the direction in which the hook 5 is put into use, as shown in FIG. The hook member has a ridge 9 at the base.

Therefore, when the finger is rotated about 90 ° clockwise from the state shown in FIG. 1 against the bias of the coil spring 12 to bring it into the retracted state shown in FIG. 2, the ridge 9 is projected at the final stage of the rotation. It abuts 7 and gets over it, and holds the hook member 3 in the retracted state against the bias of the coil spring 12.

In order to put the hook in the use state shown in FIG. 1, the hook member 3 is pushed with a finger in the direction of the arrow shown in FIG. 2, whereby the hook member is slightly rotated counterclockwise to get over the projection 7 on the ridge 9. Then, the hook member will be the coil spring 12 until the extension 11 protruding beyond the base 3'abuts the protrusion 7 from below.
The hook 5 is rotated by the urging force of and the hook 5 comes out.

Since the base portion 3'has the arcuate slits 8, a large force is not required to allow the ridges 9 to get over the projections 7. And
The hook member receives the urging force of the coil spring both in the retracted state and in the used state and presses the ridge 9 and the extension 11 against the projection 7, so that the hook member does not rattle due to vibration or the like. Further, the complete storage of the hook member can be confirmed by the feeling that the ridge 9 gets over the projection 7.

In the second embodiment shown in FIGS. 4 to 6, the coil spring 12 is wound around the shaft 4 similarly to the first embodiment. However, in this embodiment, one end 12a of the coil spring is connected to the spring bearing 13 on the inner surface of the storage chamber.
And the other end 12b is applied from above to a ridge 14 ′ whose phase is different from that of the ridge 14 by 90 °.
The hook member 3 is rotationally biased so that the hook 5 is in the retracted state shown in FIG. The hook member has a ridge 10 at the base. Therefore, when the coil spring 12 is rotated about 90 ° in front of the hook member against the bias of the coil spring 12 from the retracted state shown in FIG. The extension portion 11 of the hook member comes into contact with the protrusion 7 from below, and is in the use state shown in FIG. In this state, the ridge 10 that has passed over the projection 7 resists the bias of the coil spring 12 and holds the hook member 3 in a used state. To return the hook member to the retracted state, rotate the hook member slightly clockwise in FIG. 4,
When the ridge 10 gets over the projection 7, the coil spring 12 urges the hook member into the state shown in FIG.

Since the base portion 3'has the arcuate slit 8, it does not require a large force to get over the projection 7 on the ridge 10. The hook member pushes the tip of the hook 5 against the back wall 2b of the storage chamber when it is in the retracted state by the bias of the coil spring, and pushes the ridge 10 against the protrusion 7 when it is in the use state. Not attached. Also, the fact that the hook is completely projected means that the ridge
It can be confirmed by the feeling that 10 gets over the protrusion 7.

The retracted hook member resists the bias of the coil spring,
In order to facilitate the operation of pulling the hook 5 toward the front side and turning it into a use state, a recess 1 ′ that allows the hook 5 to be touched from above with a finger is provided at the upper part of the housing 1 in communication with the storage chamber. good.
