ABSTRACT:
A lens drive apparatus and its producing method are provided in which the productivity is improved and the assembly of components is conducted at high accuracy. In particular, a movable optical system containing an objective lens and a stationary base are coupled by elongated resilient members which serve as suspensions and are provided at both ends with joining members made of a resin material. The resilient members and the joining members are formed in combination by insertion-molding. Accordingly, their assembly can be executed so that troublesome work such as directly assembling the resilient members of delicate size is avoided, no exceptional skill is needed, and less steps are involved for ease of production, thus increasing the productivity. Also, the joining members are comparatively large in size and can thus be mounted at high positional accuracy to both the stationary base and the movable optical system. The joining members and the resilient members are coupled at high accuracy to each other by means of insert-molding. Hence, the positional relation between the stationary base and the movable optical system will highly be enhanced in accuracy.
