Abstract

See full text

A lens drive unit that prevents an actuator from being inclined is provided. In the lens drive unit, when a lens frame is displaced in a direction orthogonal to a direction in which the actuator extends and contracts with respect to a base member by, for example, impact from an outside of the lens drive unit, a drive shaft of the actuator abuts on a first lateral wall and a column, so that the actuator is prevented from being inclined with respect to the base member.
