Lid lock apparatus for vehicle

Abstract

The invention provides a lid lock apparatus for a vehicle which is smoothly operated. An electric motor (3) provided within the lid lock apparatus (1) is operated to rotate a worm wheel (5) via a worm (4) so that a lock shaft (6) advances and retreats relatively to a housing (2) and makes the lid engage and disengage from the vehicle main body. An engagement pole (53) engaged with the lock shaft (6) is formed on the worm wheel (5). The lock shaft (6) includes a support portion (62) driven by the housing in the thickness direction, a relief portion (64) biased to a support portion (62) for arranging the worm wheel (5), and a relief portion (64) provided with an interlock bore (65) for allowing the engagement pole (53) to insert in the thickness direction. The inner peripheral surface of the interlock bore (65) is projected inwards in the guide center so that the engagement pole (53) and the interlock bore (65) are engaged near the guide center in the thickness direction of the support portion (62).

Description

technical field [0001] The present invention relates to a lid lock device for a vehicle that locks a lid provided on a vehicle body in a closed state. Background technique [0002] As a prior art, there is a vehicle lid lock device in which a shaft member protrudes from a casing by elastic force and engages with a lid provided on a vehicle body to lock the lid in a closed state (see Patent Document 1). In such a vehicle lid lock device, by operating the electric motor inside the case and rotating the worm wheel, the shaft member can be moved against the elastic force, and the engagement with the lid can be released to open the lid. [0003] In the prior art described above, the driving device is arranged in an overlapping manner in the thickness direction of the shaft member and the housing to reduce the thickness direction dimension of the hood lock device for a vehicle, the driving device includes a device for generating The driving force is transmitted to the worm of th...

Problems solved by technology

[0009] In order to prevent the above situation, it is conceivable to integrally form a large-diameter drop-off prevention part on the upper end of the holding part, but this will lead to deterioration of workability when assembling the stopper on the holding part.

In addition, there is a method of attaching a separate retaining member to the holding portion after the stopper is attached to the holding portion, but the number of parts of the cover lock device increases, and the assembly man-hours also increase.

Furthermore, when assembling the stopper on the holding part, the stopper may be bonded to the holding part with an adhesive or the like, but the bonded part of the stopper will soon be dislodged due to repeated bending. keep out
