ABSTRACT:
An autofocus actuator is provided with a yoke320that comprises an inner cylindrical portion321defining an insertion bore35through which a hollow body portion of a holder is adapted to be received and an outer cylindrical portion322provided outside of the inner cylindrical portion with a predetermined spacing left between the inner cylindrical portion and the outer cylindrical portion by a connecting portion324. Four tab-shaped portions325are integrally formed with an end surface of the outer cylindrical portion322of the yoke in such a manner that the tab-shaped portions remain flush with the end surface of the outer cylindrical portion and extend outwardly from the outer cylindrical portion. The tab-shaped portions325are so formed as to leave a concave portion327between the adjacent tab-shaped portions. This assures that the tab-shaped portion325can make contact with a leaf spring in a broader area, thus enabling the leaf spring to be reliably bonded to the yoke320. Moreover, the yoke320can be aligned with ease by disposing a part of a support frame within the concave portions327formed between the adjacent tab-shaped portions325.
