Therefore, when the latch mechanism 70 is released to open the door, the grip 22 is gripped and slid from the lock position to the basic position (front movement end), and subsequently to the latch release position (outside rotation end). The latch mechanism 70 including the unlocking can be released simply by operating the grip 22, and the releasing operation can be easily performed. In particular, the sliding operation toward the front of the vehicle (in the direction of arrow a) and the rotation operation toward the outside of the vehicle (in the direction of arrow c) coincide with the operation for opening the vehicle door, and the latch is released while the grip 22 is held. The door can be opened and operated continuously after the rotation to the position.

  In addition, since the latch release operation including unlocking can be performed only by operating the grip 22 as described above, the number of parts can be increased compared to the case where a lock knob or the like is provided separately from the grip 22 to perform locking and unlocking. The latch release operation device 20 is simple and inexpensive.

  Further, when the grip 22 is slid to the lock position, the lock mechanism 76 is mechanically operated via the lock cable 78 and the release of the latch mechanism 70 by the outer door handle is prevented. The operating device 20 is simpler and less expensive.

  Further, the inner door handle is disposed in the handle pocket 26 so as to be rotatable around a support axis O that is substantially coincident with its own axis center and to be slidable in the axial direction by a long cylindrical grip 22. Therefore, the rotation operation and slide operation of the grip 22 can be easily performed with a small operation stroke, the arrangement space including these operations can be small, and the latch release operation device 20 is compactly arranged. it can.

  The grip 22 includes a small-diameter cylindrical part 60 that is substantially concentrically integrated, and is provided with a notch part 64 that is a part of the small-diameter cylindrical part 60 that is notched so that the latch mechanism 70 is mechanically released. One end portion of 72, that is, the connecting terminal 74 is inserted into the inside of the small diameter cylindrical portion 60 from the notch portion 64, and is latched to the latch interlocking connecting portion 66 provided inside the small diameter cylindrical portion 60. The operating device 20 can be configured more compactly.

  Further, a stepped recess 90 is provided on the outer peripheral surface of the small-diameter cylindrical portion 60, and the rotation operation to the latch release position side is prevented or moved to the latch release position by the relative position with the stopper 44 in the axial direction. Therefore, the latch release operation device 20 can be configured more simply and inexpensively. That is, at the locked position (rear side moving end), the stopper 44 comes into contact with the second step 96 of the stepped recess 90 to prevent the grip 22 from rotating toward the latch release position (in the direction of the arrow c). At the position (front moving end), the grip 22 is allowed to rotate toward the latch release position (in the direction of arrow c), and further rotation is prevented by the stopper 44 coming into contact with the first step 94. The latch release position is defined, and the single stopper 44 has both the function of preventing the rotation to the latch release position and the function of positioning the latch release position. Composed.
