<P>PROBLEM TO BE SOLVED: To provide an automatic opening/closing unit for a vehicle, which reduces a frictional noise of a cable, and which is equipped with a tensioner mechanism capable of preventing a coating from coming off a guiding groove of a driving drum and the cable. <P>SOLUTION: The driving drum 34, the outer peripheral surface of which is provided with the spiral guiding groove 34a, is arranged in the case of the drive unit; and the tensioner mechanism 41b, which is provided between a cable entrance/exit portion 31c of the case and the driving drum 34, is provided with a tensioner pulley 53 over which the cable 23a is to be looped, and a pulley holder 52 for holding the tensioner pulley 53. The tensioner pulley 53, which is attached in a turnable and axially movable manner between both side walls 52a1 of the pulley holder 52 via a pulley shaft 54, is moved in an axial direction along the pulley shaft 54 depending on a change in the angle β of the cable 23a, which is changed along with the rotation of the driving drum 34. <P>COPYRIGHT: (C)2011,JPO&INPIT |
