Abstract
A drive device for driving an optical element suitable to be attached to a camera shake correction device. The drive device employs items molded from a synthetic resin in which the elastic deformation of the synthetic resin allows the oscillation of a piezoelectric element to be adequately converted to drive power. The drive device includes an electromechanical conversion element, a baseplate equipped with a securing area secured to one end of the electromechanical conversion element, and a drive member that is securely linked to the other end of the electromechanical conversion element and displaced together with the electromechanical conversion element. The device further includes a transport member constructed from a rigid synthetic resin material with a Rockwell hardness of about 120 or more and which is frictionally linked to the drive member.
