Abstract
A drive apparatus includes a rail, a shaft, and a motion body. At least a part of the rail is curved such that an opening groove of the rail is curved when the rail is seen from a side orthogonal to an axial direction. The shaft includes flexibility. The shaft includes an engagement portion which is formed in a spiral shape at a circumferential surface thereof. The motion body includes a case portion and an engaged portion held by the case portion so as to be movable, the engaged portion extending inside the rail through the opening groove from an outward of the rail, the engaged portion engaged with the engagement portion of the shaft. The engaged portion is movable in a first direction, and includes an orientation fixed relative to the case portion in a second direction which is orthogonal to the first direction.
