Abstract
A drive unit includes an actuator main body configured to vibrate to output a driving force, a movable body, which is contacted by the actuator main body and is movable relative to the actuator main body in a predetermined moving direction, and an opposing member positioned to face the actuator main body with the movable body interposed therebetween and hold the movable body together with the actuator main body so that the movable body is sandwiched therebetween. A portion of the movable body, which contacts the opposing member, has an elastic modulus lower than that of the opposing member.
