Next, the operation will be described. (Operation of FIGS. 5 and 6) When the door is closed, the striker 33 on the vehicle body side engages with the engagement groove 58 of the latch 34 of the lock device on the door side, and the latch 34 rotates forward (clockwise).
The pawl 55 is engaged with the full lock engagement step 56 of the latch 34 to prevent the latch 34 from reversing, thereby completing the door closing. FIG.
Is in a locked state, so that even if the outer handle is opened to rotate the outer door opening lever 14 to the left and the lever link 35 is moved downward in the f direction, the abutting portion 39 is in contact with the abutting piece 54.
The door cannot be opened because the contact portion 39 simply moves downward in the direction of the arrow f without swinging, and the door cannot be opened. However, when the inner cable 21 is pulled and the inner door opening lever 19 is rotated upward, one motion is performed. Can be opened.

That is, when the inner cable 21 is pulled by operating the inner opening handle, the inner opening lever 19 moves upward about the ratchet shaft 13 and is formed in a part of the inner opening lever 19. The release piece 57 of the ratchet 51 is pushed upward by the projection 49 (FIG. 6). For this reason, the ratchet 51 is turned to the left around the ratchet shaft 13, and the cancel lever 50 is integrally fixed to the ratchet 51 by means such as tacks or spot welding.
Is also turned to the left, and the cancel projection 53 formed on a part of the cancel lever 50 also rotates about the ratchet shaft 13. Thus, since the cancel pin 53 of the lever link 35 projects in the rotation locus of the cancel protrusion 53, the cancel protrusion 53 is
8, and the cancel pin 38 is pushed out of the vehicle.

As described above, when the cancel pin 38 is pushed by the cancel projection 53, the lower end of the lever link 35
Since the contact portion 39 of the lever link 35 moves to the upper side of the contact piece 54 because the upper protrusion 36 moves to the outside of the vehicle around the center, the outer handle is opened and the outer door lever 14 is moved. When the lever link 35 is turned to the left and the lever link 35 is moved downward in the direction f, the contact portion 39 comes into contact with the contact piece 54 so that the door can be opened.

On the other hand, when the ratchet 51 is rotated leftward in FIG. 6, the pawl 55 is rotated, and the pawl 55 is disengaged from the full lock engaging step 56. Therefore, the latch 34 is reversed, and in FIG. 6, the door is opened by the elasticity of the seal rubber. That is, at the moment when the pawl 55 is disengaged from the full lock engagement step 56, the door is opened by the elasticity of the seal rubber. Therefore, it can be said that FIG. Even if it comes off from the part 56, there is a solid difference, and depending on the lock device,
In some cases, the claw 55 does not come off the full lock engagement step 56. Therefore, the rotation of the inner opening lever 19 by the inner opening handle is made a little extra in consideration of some safety. Therefore, the pushing action of the cancel pin 38 by the cancel projection 53 is also
The extra part may be damaged in some cases, but the present invention solves this with FIG.

(Operation of FIG. 7) Returning to FIG. 6, looking at the inner cable 21, a joint pin 25 is fixed to the inner cable 21. In FIG. 6, the joint pin 25 is connected to the bent portion 1 of the outer door opening lever 14.
8 just hits the lower surface. That is, the moment the claw 55 separates from the full lock engagement step 56,
Is attached at the timing of abutting against the lower surface of the bent portion 18. Therefore, when the inner opening handle is excessively rotated further, the bent portion 18 is moved upward by the joint pin 25, and the outer opening is performed. The door lever 14 is rotated. When the outer door opening lever 14 rotates, the lever link 35, which is fixed to a part of the outer door opening lever 14, is moved downward.
Numeral 8 escapes downward by .alpha., And escapes from further pushing of the cancel pin 38 by the cancel projection 53, thereby preventing breakage.
