Also, rattling of the holder body 2 with respect to the guide rail 4 can be effectively prevented.

That is, in the present embodiment, the torsion coil spring 3 is movably attached to the housing 1 via the piece member 14 by moving the piece member 14 with respect to the slide groove 13. Can be greatly deformed, so that a large urging stroke can be obtained even if the overall size is shortened, as compared with the case where a compression coil spring or the like is used as the urging means. That is, the main body 2 can be completely pushed out of the housing 1.

Also in this embodiment, when the holder main body 2 is pushed into the housing 1 against the urging spring pressure of the torsion coil spring 3, the lock claw 19 is again brought into contact with the spring of the compression coil spring 20. The holder body 2 is automatically locked in the locking recess 28 on the holder body 2 side by the pressure, and the holder body 2 is locked in the housing 1. In such a locked state, for example, at the time of collision of a car or sudden Even when a large inertia force is applied during braking or the like, the locking claw 19 is securely locked in the locking recess 28, and the locked state is not released. There is no need to worry.

Incidentally, in the above embodiment,
Although the present invention is intended for a cup holder device, the present invention is not limited to this, and may be applied to various kinds of automobile drawer devices having a push-open function, such as other ashtray devices and accessory storage devices. Needless to say, the present invention can be easily implemented and applied.

[0022]

As described above, according to the present invention, by adopting the above configuration, the torsion coil spring is used as the urging means, and the main body of the torsion coil spring is used as the bridge member which moves in the slide groove of the housing. Due to the mounting, the torsion coil spring can be greatly deformed by the movement of the bridge member with respect to the slide groove, so the installation space is extremely small as compared with the one using a compression coil spring, and the drawer itself has been made more compact. However, it is possible to obtain a large urging stroke and sufficiently push the drawer outward to the end. Further, the torsion coil spring is mounted on the bridge member in a state where the open coil-shaped main body portion is compressed by the pressing claw of the bridge member. There is no need to worry about rattling in the vertical direction, and mounting on the bridge member can be performed simply and securely since it is only necessary to get over the holding claw and fit it.
