Abstract
In a biaxial actuator for an optical pickup, rising pieces are bend-formed on a base member on which a lens holder having an objective lens is placed in such a way as to be able to displace in a focusing direction and in a tracking direction. The strength of the base member is increased by setting the width of the bend-formed portion at the root of each of the rising pieces in such a way as to be larger than the width of any other part of the associated rising piece. Preferably, the shape of a side elevation section of each of the rising pieces is set to be a trapezoid.
