To reduce the weight of the movable body while simplifying the structure. Included are: a first movable body that is movable in a first movement direction with respect to a base body; a second movable body that is positioned on an opposite side of the first movable body from the base body and movable in a second movement direction different from the first movement direction with respect to the first movable body; and a first drive body and a second drive body that each apply driving force to the second movable body, in which the first movable body and the second movable body are integrally moved in the first movement direction with respect to the base body by the driving force of at least one of the first drive body or the second drive body, and the second movable body is moved in the second movement direction with respect to the first movable body by the driving force of at least one of the first drive body or the second drive body.
