Abstract
The vibration-type-motor driving apparatus includes a vibration-type motor including a vibrator on which vibration is excited by an electro-mechanical energy conversion element, a shaft that supports the vibrator, and a rotor that contacts the vibrator to be rotated thereby. A first end portion of the shaft is moved with the vibration of the vibrator. The apparatus further includes a housing that houses therein the motor, and a first elastic member that contacts the first end portion of the shaft and is deformable in a direction in which the first end portion vibrates. The first elastic member transfers heat of the shaft to the housing or another member provided inside the housing.
