The release lever is disengaged from the inner edge of the through opening when the release lever is slid in the unlock direction when the release lever is slid in the unlock direction by being urged in the locking direction by the portion, and the lock is released. A lock structure for a lid of an armrest is provided.

According to the present invention, a spring for urging the release lever on the vehicle compartment side of the lid in the locking direction is formed by a substantially Ω-shaped wire spring, and the center of the wire spring is formed by the shaft of the lid. By supporting and holding both ends on the release lever, the release lever can be urged in the locking direction by one wire spring.

According to a second aspect of the present invention, the shaft portion of the lid is a shaft portion of an anti-theft dial rotatable from the trunk room side. And the dial is prevented from falling out, and the rotation of the dial is moderated by the square shaft formed at the bottom of the ring groove.

According to this structure, the shaft portion of the anti-theft dial rotatable from the trunk room side is used as the shaft portion of the lid, and the central portion of the wire spring is fitted into the ring groove of the shaft portion. The wire spring can be supported by the shaft at the same time that the dial can be retained. Further, by forming a square shaft portion at the bottom of the ring groove of the shaft portion of the dial, moderation can be given to the rotation (for example, 90 degrees) of the dial.

Further, as in claim 3, both ends of the wire spring penetrate through the arc-shaped long hole of the lid having a length that allows the sliding operation of the release lever, and are formed on the inner surface of the dial. A locking portion is formed in this long hole, which locks both ends of the wire spring that moves as the release lever slides in the unlocking direction when the dial is rotated to the locking position. It can be a structure that has been.

According to this configuration, when the dial is rotated to the locked position by rotating the dial to the lock position by inserting both ends of the wire spring through the arc-shaped long hole of the lid and engaging with the arc-shaped long groove on the inner surface of the dial. When the release lever is unlocked from the side, both ends of the wire spring that moves with this release are locked by the locking portion of the arc-shaped long groove, and the release lever cannot be slid further. Can not be opened.

Further, if the wire spring has a structure in which a loop portion for relaxing stress is formed between the center portion and both end portions of the wire spring, an excessively large portion is formed at the bent portion of the wire spring. No stress is applied.

The dial 10 is rotated between an unlocked position (see FIG. 3A) contacting one end of the dial and a locked position (see FIG. 3B) contacting the other end of the elongated hole 8d. You can operate it.

A central portion 11a of a substantially Ω-shaped wire spring 11 is fitted into the ring groove 10b of the shaft portion 10a of the dial 10 from the cabin side to prevent the dial 10 from falling out into the trunk room. I do. Also, since the intermediate portion 11a of the wire spring 11 fitted into the ring groove 10b abuts on the square shaft portion 10c, the dial 1
Moderation is given to a 90 degree rotation of zero. The wire spring 11 is supported by the shaft 10a by fitting the intermediate portion 11a into the ring groove 10b of the shaft 10a.

Both ends 11 of the wire spring 11
The b and 11b pass through the arc-shaped long holes 8f and 8f of the lid 8 set to a length that allows the sliding operation of the release lever 9, and are inserted into the arc-shaped long grooves 10e and 10f formed on the inner surface of the dial 10. Each is engaged.

On the inner surface of the release lever 9, projections 9b, 9b having a substantially U-shaped cross section corresponding to both ends 11b, 11b of the wire spring 11 are formed.
The release lever 9 is urged in the locking (upward) direction by bringing the b and 9b into contact with both ends 11b and 11b, respectively.

The arc-shaped long grooves 10e, 1 of the dial 10
At 0f, when the dial 10 is rotated 90 degrees counterclockwise from the unlocked position of FIG. 3A to the locked position of FIG. 3B, the release lever 9 slides in the unlocking direction. Accordingly, locking portions 10g, 10g for locking both ends 11b, 11b of the wire spring 11 lowered by the protrusions 9b, 9b so as not to further lower are formed. That is, the long groove 10e on the left side in the figure.
10g is a convex portion protruding inward from one side edge of the long groove 10e, and the locking portion 1 of the long groove 10f on the right side in the drawing.
0g is the lower edge of the long groove 10f.

As shown in FIG. 1, an upper moving stopper projection 8g and a lower moving stopper projection 8h are formed on the upper part 8a of the lid 8 on the passenger compartment side. The protrusion 9c is stopped at the upper movement position and the lower movement position.

With the above-described lock structure, at the time of assembly, the shaft portion 10a of the dial 10 is fitted into the fitting hole 8c of the lid 8 from the trunk room side, and the central portion 11a of the wire spring 11 is fitted from the vehicle room side.
