PURPOSE:To lower the resonance acuteness of a primary resonance value to improve the frequency response and reduce an unnecessary rolling phenomenon by using a whisker impregnated with resin as the elastic member which supports a mobile member. CONSTITUTION:The whisker is impregnated with resin to obtain an elastic member 30. That is, the elastic member 30 used in an optical system driving device consists of the potassium titanate whisker impregnated with resin, and nylon 6, nylon 66, polyacetal, or the like is used as resin with which the whisker is impregnated. One end of the elastic member 30 constituted in this manner is stuck to the mobile member as a body to be driven and the other end is stuck to the base as a fixed material to support the body to be driven. For example, if this elastic member 30 is used in the part of a spring member 36, the peak value of the primary resonance value is reduced and a well-damped frequency characteristic is attained. Thus, the optical system driving device is obtained where the unnecessary rolling phenomenon is reduced.
