Abstract:
1. A driving device comprising: an electromechanical transducer that is extended and contracted by application thereto 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, wherein the movable body has a main element therefor; a pinch member that is assembled on the main element and configured to pinch and hold the support member; the pinch member having a first end configured to be biased by a biasing member that biases the pinch member toward the support member; the pinch member having a second end configured to abut and pivot relative to the main element based on a biasing force applied by the biasing member; and wherein the pinch member 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.
