Door locking device for vehicles
First Claim
1. A door locking device for vehicles, comprising a device body having a recess on the front side thereof, a mounting space on the rear side thereof and a mounting member at the lower portion thereof;
- a latch and a ratchet supported in said recess so that, when a striker fixed to a chassis engages said latch to turn the latch counter-clockwise, said ratchet disengageably engages said latch to prevent said latch from being reversely turned;
an opening lever supported pivotably in said mounting space for connecting to a door handle;
a locking lever supported in said mounting space so that said locking lever can be turned between an unlocking position in which said opening lever and said ratchet are engaged with each other, and a locking position in which said opening lever and said ratchet are disengaged from each other, and having a first fan-shaped gear portion;
an actuator provided on said mounting member, adapted to switch said locking lever from a locking position to an unlocking position, and vice versa, and having a motor, reduction gears, a one-way clutch and an output shaft which are supported on a frame, wherein said output shaft is provided in parallel with a central shaft of said locking lever;
a case attached to said mounting member and sealing said actuator so that only said output shaft of said actuator extends through said case to project from a rear side of said device body; and
a second fan-shaped gear portion mounted fixedly on said output shaft and meshed with said first gear portion.

Abstract
In the door locking device for vehicles according to the present invention, a motor type actuator for switching the locking device from a locked state to an unlocked state, and vice versa is modularized. A locking lever in this locking device has a first fan-shaped gear portion. The actuator has a motor, reduction gears, a one-way clutch and an output shaft which are supported on a frame. The actuator is set on a mounting portion of a device body and thereafter sealed with a case. The output shaft is provided in parallel with a central shaft of the locking lever, and extends through the case to project beyond the rear surface of the device body. A second fan-shaped gear portion meshed with the first fan-shaped gear portion is mounted fixedly on this projecting portion of the output shaft.
