摘要： An autofocus actuator is provided with a yoke 320 that comprises an inner cylindrical portion 321 defining an insertion bore 35 through which a hollow body portion of a holder is adapted to be received and an outer cylindrical portion 322 provided outside of the inner cylindrical portion with a predetermined spacing left between the inner cylindrical portion and the outer cylindrical portion by a connecting portion 324. Four tab-shaped portions 325 are integrally formed with an end surface of the outer cylindrical portion 322 of 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 portions 325 are so formed as to leave a concave portion 327 between the adjacent tab-shaped portions. This assures that the tab-shaped portion 325 can make contact with a leaf spring in a broader area, thus enabling the leaf spring to be reliably bonded to the yoke 320. Moreover, the yoke 320 can be aligned with ease by disposing a part of a support frame within the concave portions 327 formed between the adjacent tab-shaped portions 325.
