ABSTRACT:
In a vibration wave driven motor which has a vibration member for forming a travelling vibration wave in a resilient member by an AC voltage being applied to an electro-mechanical conversion element adhesively secured to the resilient member, and a member urged against the vibration member with pressing means interposed therebetween and in which the member and the vibration member are moved relative to each other by the travelling vibration wave formed in the resilient member, there is provided forcibly cooling means for forcing a cooling medium to circulate in the heat generating portion of the motor to thereby cool the same.
