Driving apparatus for vehicle

A driving apparatus for a vehicle, comprising:

• a rotation member on which a rope member for transmitting a driving force of a drive source is hooked;
• a support pin being inserted into the rotation member along an axial direction of the rotation member, including a flange for stopping a movement of the rotation member in one direction in the axial direction, including a circumferential groove formed at an end portion that penetrates through the rotation member, the support pin rotatably supporting the rotation member;
• an annular elastic member supported relative to the circumferential groove, the annular elastic member configured to reduce a diameter in a radial direction;
• and
• a support member including an attachment hole in which the end portion of the support pin that penetrates through the rotation member is idly provided, the support member including an inwardly protruding flange provided at the attaching hole to protrude at a position closer to the flange than the annular elastic member in an axial direction, the inwardly protruding flange having an inner diameter equal to or greater than an outer diameter of the annular elastic member when the annular elastic member is in an elastically deformed state having reduced diameter within the circumferential groove and smaller than the outer diameter of the annular elastic member when the annular elastic member is in an elastic recovery state where the diameter expands.
