Driving device

Abstract

A driving device includes an electromechanical transducer that is extended and contracted by application of voltage, and a support member that slidably supports a movable body and that is displaced together with the electromechanical transducer to which the support member is connected, the movable body being driven along the support member with the extension and contraction of the electromechanical transducer. The movable body has a main element, a pinch member that is assembled on the main element so as to pinch and hold the support member, and a biasing member that biases the pinch member toward the support member. A part of the pinch member abuts on the support member and other part thereof is held on the main element in a cross section perpendicular to a movement direction of the movable body when the pinch member is biased by the biasing member.
