(Problem to be solved by the invention) Therefore, it is difficult to connect the connecting part of the split lever to the case in a sealed state, and in the above-mentioned known lever, the inside and outside of the base of the case are in an intricate combination. Therefore, there was a problem that the configuration was complicated.

(Means for solving the problem) The present invention is aimed at solving the above problem, and includes a locking lever that can freely swing between a locking position and an unlocking position on the locking device body. , a drive device for a vehicle door lock in which an operating lever that swings by power is connected to the locking lever, wherein the operating lever is divided into a first lever outside the case and a second lever inside the case, and the second lever is connected to the second lever. A support shaft that is rotatably supported by the case is provided, and a non-circular engagement shaft portion is provided on the protrusion portion of the support shaft that protrudes outside the case, and a truncated conical point protrudes from the tip of the shaft portion. and the engaging shaft portion is engaged with a non-circular engaging recess provided in the first lever, and the pointed portion is press-fitted into a shaft hole provided in the first lever. shall be.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 indicates a locking device main body, 2 indicates a known locking lever provided on the back of the locking device main body, and the lever 2 has both ends attached to the locking device. Opening the door lock device by connecting the cylinder lock and the lock knob through the
An actuating lever 3 that swings by power is attached to the protruding piece in the middle, and the actuating lever 3 is connected to a first lever 5 outside the case 4 and the case 4.
As shown in FIG. A non-circular engagement shaft portion 7a and a truncated conical pointed portion 7b projecting from the tip of the shaft portion 7a are provided on a protruding portion of the support shaft 7, which is rotatably supported within the case 4, and is protruded from the outside of the case 4. , the engagement shaft portion 7a is engaged with a non-circular engagement recess 8 provided in the first lever 5, and the pointed portion 7b is press-fitted into a shaft hole 9 provided in the first lever 5; In this way, the lower edge of the pointed head 7b seals the shaft hole 9, and furthermore, the second lever 6 has a head from which the support shaft 7 protrudes, and opens an arc-shaped insertion hole 10 around the support shaft 7. It consists of a generally disc-shaped body and legs having rotation regulating pieces 12 that come into contact with a pair of left and right walls 11, 11 provided on the inner wall of the case 4, and a leg section with a rotation regulating piece 12 that comes into contact with a pair of left and right walls 11, 11 provided on the inner wall of the case 4. A cam 14 having stepped action points 13, 13 is formed on both sides of the insertion hole 10, extending from the edge to the rotation regulating piece 12. A rotary member 16 having a strip 15 protruding in the radial direction is superimposed on the back surface of the second lever 6, and the support shaft 17 of the rotary member 16 is fitted into the insertion part 10, and the rotary member 15 is attached to the case 4. installed motor 1
The rotating member 16 has a first semicircular groove 20 in which a coil-shaped return spring 19 is inserted, and a pair of grooves protruding from the inner wall of the case 6. A second semicircular groove 22 into which the stopper 21 is fitted is continuously provided, so that when the rotating member 16 is rotated, the end of the return spring 19 in the rotation direction is held by the stopper 21 and compressed. Due to the release of the compressive force, the rotating member 16
is returned to the neutral position by the return spring 19, and the protrusion 15 is returned by the amount of rotation, and both partition walls 11, 11
is located at an intermediate position, and at this position the protrusion 15
The support shaft 17 of the rotating member 16 and the support shaft 7 of the operating lever 3 are aligned on the radial axis of the rotary member 16.

(Effect of the invention) In this way, according to the invention, the operating lever 3, which is divided into the first lever 5 outside the case 4 and the second lever 6 inside the case 4, has a shaft attached to the case 4 with the second lever 6. A supporting shaft 7 to be supported is provided in a protruding manner, and a non-circular engagement shaft portion 7a is provided on a protruding portion of the supporting shaft 7 that protrudes outside the case 4, and a truncated cone-shaped engaging shaft portion 7a is provided on a protruding portion of the supporting shaft 7 that protrudes outside the case 4. A pointed head 7b is provided, and the engaging shaft part 7a engages with a non-circular engagement recess 8 provided on the first lever 5, and the pointed head 7b is provided on the first lever 5. Since the first lever 5 is press-fitted into the shaft hole 9, the engagement shaft portion 7a of the first lever 5 is engaged with the support shaft 7 in a rotation-preventing manner, and the pointed portion 7b thereof is engaged with the support shaft 7 in a non-slip manner. Therefore, they can be easily and firmly connected without using screws or the like, and the lower edge of the pointed head 7b covers the shaft hole 9, making it easy to seal the case.
