However, in the conventional device described above, the active lever and the passive lever are disengaged by the slide pin, so that when the active lever and the passive lever are rotated, that is, when the close lever is closed, the slide is performed. The pin will move radially along the slot of the cancel lever along with the passive and active levers. For this reason, when rotating the cancel lever during the closing operation, the distance from the center of rotation of the cancel lever to the slide pin, that is, the lever ratio of the cancel lever changes depending on the operation timing, and as a result, the operation of the cancel lever becomes heavy. There was a fear.

Therefore, an object of the present invention is to improve the operability of the cancel lever.

[0006]

In order to solve the above-mentioned technical problems, the technical means adopted in the present invention is to support a passive lever so as to be relatively rotatable on an active lever and to attach the passive lever to the active lever. An engagement pin is provided on the rotation center, the engagement pin being disengageable from the cancel lever.

According to this technical means, during the closing operation, the engaging pin is always located on the center of rotation of the active lever and does not move, so that the lever ratio of the cancel lever is always constant. Therefore, the operation of the cancel lever does not become heavy depending on the operation timing, and good operability is obtained.

[0008] More preferably, the span from the center of rotation of the passive lever to the engagement pin is equal to or greater than the span from the center of rotation of the passive lever to the link point between the latch mechanism and the passive lever. It is preferable to arrange the engaging pins as described above.

[0009] More preferably, a stopper member is provided for holding the passive lever so as to contact the passive lever and set a predetermined gap between the engagement pin and the cancel lever.

At this time, the engagement pin 34c
Is located on the center of rotation of the active lever 33, the position is constant and does not displace. As a result, the latch 21 rotates counterclockwise as shown in FIG.
The second engagement claw 21c and the pawl 22 are engaged with each other, and the latch 2 enters the full latch state. As a result, the slide door 4 is held in a completely closed state. Thereafter, the motor 32 is driven in the opposite direction to the above, and the active lever 33 is driven.
Returns to the initial state, as shown in FIG.

When the outside handle 41 is operated in the completely closed state of the slide door 4, the connecting link 72
The connecting lever 71 rotates counterclockwise as shown in FIG. As a result, the open lever 26 is rotated to release the engagement between the pawl 22 and the second engagement claw 21c of the latch 21, and the latch mechanism 2 enters the unlatched state. At this time, the cancel lever 35 is also rotated by the counterclockwise rotation of the connecting lever 71 shown in FIG. 10, but a predetermined gap is provided between the engaging surface 35a of the cancel lever 35 and the engaging pin 34c. Since D is set, the cancel lever 35 is not twisted, and can be smoothly rotated. That is, there is no load on the operation of the outside handle 41. When the outside handle 41 is operated during the closing operation described above, FIG.
As shown at 0, the connecting lever 71 rotates counterclockwise as shown in FIG. This allows
The cancel lever 35 is connected to the link arm 7 of the link lever 71.
1b and the abutment flange 35c of the cancel lever 35, the counterclockwise rotation shown in FIG.
