A vertical recessed rail 19 is formed on one side of the inner surface of the opening of the bezel 13 (see FIGS. 6 (a) and 6 (b)), and a lid 14 is provided at the lower end of the lid 14. A lock member 20 is provided which projects laterally from the side surface notch 14b of 14 and is fitted into the rail 19 (see FIG. 5).

A reversing spring 21 made of a wire spring is arranged in the box 11, and one end portion 21 of the reversing spring 21 is arranged.
The a is locked to the spring bracket 22 fixed to the inner surface of the standing wall 10a of the instrument panel 10, and the other end 21b is locked to the curved portion of the hinge lever 15.

The reversing spring 21 moves the hinge lever 15 in the lid closing direction (first
Reverse bias is applied in the lid opening direction (see the solid line in the figure) and in the lid opening direction (see the alternate long and short dash line in FIG. 1).

A wire spring 23 is wound around the second hinge shaft 18, one end 23a of the wire spring 23 is locked by the hinge lever 15, and the other end 23b is locked by the lid 14.
The wire spring 23 biases the lid 14 in the upward swing direction.

As shown in FIGS. 4 and 7, a recess 14a is formed at the lower end of the lid 14, and a push knob 24 is provided in the recess 14a.
Is provided, and the push knob 24 is biased downward (in the protruding direction) by a coil spring 25.

As shown in FIGS. 8 (a) and 9, the lock member 20 is formed in a substantially triangular shape, and the first top portion 20a has a lid 14a.
Is rotatably attached to a support shaft 26 provided upright on the inner surface of the support shaft 26, and is urged by a wire spring 27 wound around the support shaft 26 in a direction (locking direction) in which the rail 19 is fitted.

The second top portion 20b of the locking member 20 is laterally projected from the side surface notch 14b of the lid 14 and fitted into the rail 19.

The second top portion 20b is held at the rail fitting position by being stopped by the lower end portion of the side surface notch 14b (see FIG. 5).

As shown in FIG. 8 (b), the entire bottom surface of the second top portion 20b is rounded so that it can be easily fitted into the rail 19 from the side.

Returning to FIG. 4, a linkage lever 29 having a central portion pivotally supported by a support pin 28 is provided on the inner surface of the lid 14, and a pin 29a at one end of the linkage lever 29 is inserted into the long hole 24a of the push knob 24. While being fitted, the pin 29b at the other end of the linkage lever 29 is fitted in the hole 20d of the third top portion 20c of the lock member 20, and the bush knob 24 is pushed to lock the lock member via the linkage lever 29. The 20 is rotated in a direction in which the second top 20b is pulled out from the rail 19.

With the above configuration, when the lid 14 is closed,
