Abstract
A driving mechanism moves a moving unit in a predetermined direction and an opposite direction that is opposite to the predetermined direction. The driving mechanism includes a worm that is coupled to a driving source and rotates to move the moving unit, a worm wheel that is meshed with the worm, and a holding portion that holds the worm. The holding portion includes a highly-regulating portion that contacts with the worm when the moving unit moves in the predetermined direction, and a weakly-regulating portion that contacts with the worm when the moving unit moves in the opposite direction. A friction coefficient between the highly-regulating portion and the worm is greater than a friction coefficient between the weak regulation portion and the worm.
