The driving mechanism includes: a rack provided on one of the base body and the bearing member, in such a manner that the rack is extended in a direction of movement of the bearing member; a gear unit provided on the other of the base body and the bearing member, and engaged with the rack; and a torque applying mechanism for applying torque to the gear unit. The gear unit includes a pair of circular gears different in diameter from each other which are stacked coaxially as one unit, and an arcuate relay gear having a pitch circle which internally touches the pitch circle of one of the pair of circular gears which is larger in diameter and externally touches the other, and connecting the pair of circular gears to each other.
