Claims (1)

[Claim for Utility Model Registration] When the door is opened, the door moves in parallel so as to protrude to the side of the vehicle body, and then slides along the side surface of the vehicle body, and a guide rail that guides the sliding movement is attached to the inside surface of the door. In a sliding door, in which a guide roller is disposed on a vehicle body and is movable in and out of a side surface of the vehicle body, the guide roller engages with the guide rail and guides the sliding of the door, and the guide roller is rotated. a roller base that is freely supported; one end is rotatably supported by the roller base; the other end is rotatably supported by the vehicle body; a swing arm provided with a positioning engagement portion that causes the guide roller to protrude and retract from the side surface of the vehicle body together with the roller base, and maintains the guide roller in a state in which the guide roller protrudes from the side surface of the vehicle body to a predetermined position; an arm locking means that can be freely engaged and disengaged from the guide roller and restrain the swing arm in a state in which the guide roller protrudes to a predetermined position when engaged; The guide on the sliding door side engages and connects with the guide roller when switching from the sliding movement to the parallel movement, and releases the engagement when switching from the parallel movement to the sliding movement. An engaging claw member provided at the end of the rail engages with the arm locking means when the sliding door changes from sliding movement to parallel movement,
An opening/closing guide mechanism for a sliding door of a vehicle, comprising arm release means for releasing the swing arm by disengaging the arm locking means from the positioning engagement portion.
