A driving apparatus of the present invention comprises: a lead screw which rotationally drives; and a follower section to hold a driven member L and to rectilinearly move based on rotation of the lead screw. The follower section comprises a first tooth and a second tooth that faced a side portion of the lead screw and are opposite to each other and a third tooth provided in a position different from those of the first tooth and the second tooth. When the follower section rectilinearly moves based on the rotation of the lead screw, power is transferred with the lead screw and the first tooth being engaged with each other, and the lead screw is in a non-contact state with the second tooth and the third tooth.
