Problems solved by technology

Moreover, a desired reduction ratio can be obtained between the worm 3b and the worm wheel 3c, but since the arrangement (position in the radial direction) of the pair of engagement protrusions 3c1, 3c2 is restricted by the size (diameter) of the worm wheel 3c, it is difficult to obtain the desired speed reduction ratio between the worm wheel 3c and the worm wheel 3c. Get the desired reduction ratio between 3c and the active rod 1
Therefore, the miniaturization of the door lock device is limited

Abstract

A door lock device (Ao) for a vehicle is provided with an opening mechanism (A1), a locking mechanism (A2), and an electric actuator (A3). The electric actuator (A3) is provided with an electric motor (51), which is driven in response to a locking operation and an unlocking operation; a worm (52), which is integrated with the output axle of the electric motor (51), and which is rotated by the electric motor (51); and a locking lever (53), which has a sector gear (53a) geared to the worm (52), and is linked to an active lever (41). An operation part (53c), which is linked to a locking knob (L)provided on the interior side of the door, is provided on the locking lever (53).

Description

technical field [0001] The present invention relates to a vehicle door lock device. Background technique [0002] As a kind of door lock device for a vehicle, it is provided with: an opening mechanism, which is appropriately provided in such a manner that the door can be opened relative to the vehicle body; The non-locking part (opening lever) actuates the movable lever to the locked position (locked position) or the unlocked position (unlocked position) and restricts or permits the movement of the opening mechanism to lock (lock) or unlock (unlock) locking); an electric actuator interposed between the movable lever and capable of driving the locking and unlocking part (opening lever) to a locked position (locked position) or an unlocked position (unlocked position); the housing, It houses the opening mechanism, the locking mechanism and the electric actuator. For example, it is disclosed in Japanese Unexamined Patent Publication No. 2006-266026. [0003] In the vehicle d...
