(Prior Art) As described in this type of device, for example, in Jikokai No. 59-109678, the main body of the lock device has a
A lock lever is provided which can swing freely between a lock position and an unlock position, and an operating lever whose one end is pivotally supported by the lever is pivotally supported by a case in the middle thereof, and
It is known that the other end is connected via a cam to a rotating member that is reciprocated by power.

(Problems to be Solved by the Invention) However, in such a device, the cam is formed with a spiral cam groove formed on one surface of the rotating member, and the follower provided on the actuating lever is inserted into the cam groove. Because they are fitted and engaged, the stroke amount of the operating lever is determined by the width of the cam groove in the rotating member and cannot be larger than the radius of the rotating member, and the follower slides on the inner wall of the cam groove. Therefore, there were problems such as high frictional resistance and the need to increase the rotational torque of the rotating member.

(Means for Solving the Problems) The present invention is aimed at solving the above problems, and is intended for use in a vehicle in which a locking lever provided on a locking device body is driven to swing between a locking position and an unlocking position. In door locks and drive systems,
The drive device includes a rotating member that is selectively driven in two directions from a neutral position, and an actuator that is swingably supported by a support shaft, is connected to the locking lever, and is swingably driven by the rotating member. the rotating member and the operating lever are provided with a member having abutting surfaces on both sides, and an abutting member having an abutting surface facing the abutting surfaces with an interval therebetween; The spindle of the rotating member is disposed between the spindle of the operating lever and the contact surface, and further includes a return spring for returning the rotating member to the neutral position.

(Function) Since the above means is provided, when the rotating member is driven in one direction, one contact surface provided on the rotating member pushes the opposing contact surface of the actuating lever, causing the operating lever to move in the same direction. When the locking lever is turned in one direction and the driving force for the rotating member is deenergized,
The rotating member is returned to the neutral position by a return spring. Also, when the rotating member is driven in the other direction, the other contact surface of the rotating member pushes the other contact surface of the operating lever,
The locking lever is operated in the other direction via the operating lever, and the driving force is deenergized to return to the neutral position.

Since the distance from the pivot of the operating lever to the contact surface is greater than the distance from the center of rotation of the rotating body to the contact surface, an increased amount of torque is transmitted to the operating lever, and the locking lever is operated forcefully. Ru. At this time, since there is little slippage between the contact surfaces, there is little friction loss, and the operating force is effectively transmitted.

The rotating member 16 is connected to the motor 1 provided in the case 4.
The rotary member 16 is interlocked with the rotary shaft 18a of No.8 through a reduction gear 18b, and the rotary member 16 has a first semicircular groove 2 on its back surface into which a return spring 19 is inserted in a coil shape.
0, a pair protruding from the inner wall of the case 6, and a second semicircular groove 22 into which the stopper 21 is inserted are continuously provided, so that when the rotating member 16 is rotated, the return spring 19 is The end in the rotating direction is blocked by the stopper 21 and compressed, and upon release of the compressive force, the return spring 19 is extended and the rotating member 16 returns to the neutral position, and the abutting portion 15 is returned by the amount of rotation. Thus, it is positioned at an intermediate position between the two partition walls 11,11. At this position, the support shaft 17 of the rotating member 16 and the support shaft 7 of the actuating lever 3 are aligned on the radial line of the contact portion 15.

Next, the operation will be explained based on Fig. 4.
As shown in Figure a, when the locking lever 2 is in the locked position, the rotation regulating piece 12 of the operating lever 3 comes into contact with the partition wall 11 on the left side of the case 4, and the return spring 19 of the rotating member 16 is in an uncompressed state. The contact portion 15 is in contact with the right contact surface 13 of the operating lever 3 at an intermediate position between the two partition walls 11, 11. When the motor 18 is driven to the unlock side in this state, the rotating member 16 rotates counterclockwise as shown in FIG.
The operating lever 3 is rotated until its rotation restriction piece 12 comes into contact with the barrier wall 11 on the right side of the case, swinging the locking lever 2 to the unlocked position, and during this time the return spring 19 is moved from the case side to the second radius Groove 22
Since one end of the stopper 21 protruding inward is blocked, as the rotating member 16 rotates, the other end is pressed and compressed by the end wall of the wide first semicircular groove 20.
At the same time as the motor stops, the rotating member 16
As shown in FIG.
remains in that position and returns to the neutral position, and its abutting portion 15 abuts the left abutting surface 13 and is positioned at an intermediate position between the partition walls 11,11.

When the motor 18 is driven from this state to the lock side, the rotating member 16 rotates clockwise as shown in FIG. The movement restricting piece 12 is rotated until it comes into contact with the partition wall 11 on the left side of the case, and the locking lever 2 is swung to the lock position. Then, at the same time as the motor 18 is stopped, the rotating member 16 is
The state will be restored.

By the way, the driver does not know whether the locking lever of the locking device for each door is in the locked or unlocked position. In the case of a malfunction such as
simply rotates from the state shown in figure a to the state shown in figure d, and the contact part 15 moves from the right side of the contact surface 13 to the left side, and even if it contacts the left side contact surface 13, the actuation lever 3 does not rotate. Since the regulating piece 12 is in contact with the left wall 11 on the case side, the operating lever 3 does not swing any further, and after the motor has stopped driving, the rotating member 16 is simply returned by the return spring, resulting in a malfunction. Trouble is prevented.

In addition, the locking lever swings by manual operation,
The rotation regulating piece 12 of the operating lever 3, which is connected to the locking lever and oscillates, is connected to the locking lever and oscillates as shown in figures a to c when changing from locking to unlocking, and as shown in figures c to a when changing from unlocking to locking. Since it is in contact with the barrier wall 11 on the side opposite to the direction of movement, and the contact part 15 of the rotating member 16 is also in contact with the contact surface 13 on the side opposite to the direction of swing, the operating lever 3 can be unlocked freely. It can swing from locking to unlocking.
