摘要
A driving apparatus according to the present invention includes: a movable part including a vibrator including a piezoelectric element and a pressurization part for bringing the vibrator into pressure contact with a base part by applying impression force to the vibrator, the movable part being linearly driven; and a cover part for receiving reactive force of the impression force through intermediation of a rolling part, the cover part being fixed to the base part by a holding part extending in a direction crossing a movement direction of the movable part, in which the rolling part is sandwiched by a guide part of the movable part extending in the movement direction of the movable part and a cover guide part of the cover part extending in the movement direction of the movable part, and the movable part is positioned on an outer side beyond a side of the holding part facing the movable part.
