<P>PROBLEM TO BE SOLVED: To provide a driver in which the cost is reduced, by reducing the assembling process, variation in drive performance is suppressed by reducing plastic deformation of a leaf spring, and disassembling and scattering of components due to falling shock can be prevented. <P>SOLUTION: The driver 10, comprising a piezoelectric element 14, a drive friction member 16 secured to one end of the piezoelectric element 14, and a moving member 18 friction engaging with the drive friction member 16, causes the moving member 18 to move relative to the drive friction member 16, by telescoping the piezoelectric element 14, wherein a leaf spring 32 for pressing the moving member 18 against the drive friction member 16 constitutes an integral member with the moving member 18. <P>COPYRIGHT: (C)2007,JPO&INPIT |
