  That is, when the third transmission cable 23 is pulled according to the operation of the inside handle 15, the release lever 85 rotates the ratchet lever 61 in the direction opposite to the rotation urging direction of the spring 59, and the connecting rod The cancel lever 81 is rotated in the direction in which 80 is pulled down.

  Thus, when the inside handle 15 is operated when the latch 32 is in the half latch state as shown in FIG. 7A, the connecting rod 80 is pulled down as shown in FIG. 8 rotates counterclockwise in FIG. 8, and the guide lever 69 coupled to the door handle coupling lever 78 slides against the spring force of the spring 83 to the left in FIG. The connecting portion 71 that rotates counterclockwise around the axis of the shaft 70 and abuts and engages with the outer periphery of the engaging pin 47 from above releases the connection with the engaging pin 47 and the closer mechanism 34. And it moves to the side which interrupts | blocks between the latches 32. FIG. At this time, the ratchet lever 61 is rotated by the first contact portion 85 a provided in the release lever 85, and accordingly, the ratchet lever 45 is rotated to a position where the engagement with the latch 32 is released.

  When the inside handle 15 is operated when the latch 32 is in the fully latched state as shown in FIG. 7B, the connecting rod 80 is pulled down as shown in FIG. 9, and the door handle connecting lever 78 is shown in FIG. 9 rotates counterclockwise, and the guide lever 69 connected to the door handle connecting lever 78 slides to the left in FIG. The connecting portion 71 that rotates counterclockwise around the axis and contacts and engages with the outer periphery of the engaging pin 47 from above releases the connection with the engaging pin 47 and the closer mechanism 34 and the latch 32. Displaces to the side that cuts off the gap. Also in this case, the ratchet lever 45 rotates to a position where the engagement with the latch 32 is released.

  That is, when the inside handle 15 is operated while the latch 32 is forcibly rotated from the half latch state to the full latch state by the operation of the closer mechanism 34, the mechanical cancel mechanism 36 releases the connection to the latch 32. Then, the guide lever 69 is slidably driven so as to displace the drive lever 68 to the side that closes the space between the closer mechanism 34 and the latch 32.

  It should be noted that the outside handle (not shown) provided in the outside handle mechanism 14 in place of the inside handle 15 in the middle of the latch 32 being forcibly rotated from the half latch state to the full latch state by the operation of the closer mechanism 34. (Not shown), the mechanical cancel mechanism 36 operates as in the case of the inside handle 15, and the drive lever 68 releases the connection to the latch 32 and shuts between the closer mechanism 34 and the latch 32. Displacement driven.

  Next, the operation of this embodiment will be described.
