Abstract
A driving apparatus reduces degradation of driving performance and durability when a driven body is displaced using a lead screw. The lead screw has a lead groove that is formed over first and second members and has first and second surfaces that face to each other in a width direction. The lead screw is rotated by a driving source. A moving member engages with the lead groove, and moves parallel to the lead screw according to rotation of the lead screw. A driven body is displaced between first and second positions according to movement of the moving member. A first energization member energizes the moving member toward the second surface when the moving member passes across a first junction that occurs at a boundary between the first and second members in a stroke where the moving member contacts with a drive surface of the first surface to be moved.
