<p>Provided is a drive mechanism comprising a stationary support member, a lever member having a displacement input portion for receiving a moving force from the outside and a bearing portion for abutting against the support member, so that the lever member engages with a driven member and rocks on the bearing portion relative to the support member in response to the input of the moving force to the displacement input portion, thereby moving the driven member in a predetermined first axis direction, and a shape-memory alloy actuator for applying the moving force to the displacement input portion. The drive mechanism is characterized in that a displacement input member having the displacement input portion and a bearing member having the bearing portion are formed, in the lever member, of a material different from that of the lever member.</p> |
