DOOR OPENING/CLOSING DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an opening/closing device for a vehicle capable of reducing the number of parts and operating more smooth opening/closing motion of the door.

SOLUTION: The door opening/closing device for a vehicle has an opening/closing mechanism 40 connecting a link member 43 connected to the door 52 and a crank arm 41 connected to a door opening/closing drive part 30 by a link 42 having a universal coupling. The connection part of the link member 43 and the link 42 and the connection part of the crank arm 41 and the link 42 are universal couplings made of three-dimensionally rotational ball joint. The link 42 transmits the output of the drive shaft 35 to the link member as retaining the straight line shape by the rotation of the ball joint in the motion of the door opening/closing mechanism 40 at the opening/closing motion of the door.
