In the actuator, a bobbin formed in a focusing direction and a tracking direction of the lens holder, and each coil wound around these bobbins,
In order to generate thrust in each of these coils, there is a yoke with a magnet placed opposite each of the coils, a leaf spring with the lens holder fixed to one end thereof, and a leaf spring fixed to the other end of the leaf spring so as to be freely rotatable. A two-dimensional actuator for driving a lens, comprising: a shaft held by a shaft; (2) In the utility model registration claim described in claim 1, both ends of the shaft to which the leaf spring is pivotally connected are formed in a conical shape, and the opposing bearing on the box frame side is formed in a concave shape to fit therein. while at least one of the bearings is screwed to the box frame,
A two-dimensional actuator for driving a lens, characterized in that the distance between the two bearings is variable.
