Claims
- 1. A vibration wave driven motor, comprising:
- a vibration member for generating a travelling vibration wave therein in response to an electrical signal applied thereto;
- a rotor provided in contact with the vibration member for receiving the travelling vibration wave;
- a cooling medium introduction pipe;
- a cooling medium discharge pipe;
- a seal member for sealing the vibration member and the rotor, the seal member having a hole formed in a side thereof to mount said cooling medium introduction pipe and to mount said cooling medium discharge pipe;
- an output shaft engaged with the rotor to take out the rotation of the rotor;
- a bearing mounted on said seal member to rotatably support said output shaft; and
- a cover medium for covering at least the introduction pipe and discharge pipe.
- 2. A motor according to claim 1, wherein said vibration member has a circular ring shape.
- 3. A motor according to claim 2, wherein a portion of said vibration member of said circular ring shape is arranged in contact with said seal member.
- 4. A motor according to claim 1, wherein said vibration member has an electro-mechanical energy conversion element to which the electrical signal is supplied, and a resilient member to which the element is adhesively secured.
- 5. A vibration wave driven motor according to claim 1, wherein said vibration member has a resilient member, an electro-mechanical energy conversion element for generating the traveling vibration wave in the resilient member, and a lead line for applying an electrical energy to the element.
- 6. A vibration wave driven motor according to claim 5, wherein said cover member covers the introduction pipe, the discharge pipe and the lead line.
- 7. A vibration wave driven motor according to claim 6, wherein a leading edge of said introduction pipe faces the portion of said vibration member.
- 8. A vibration wave driven motor according to claim 7, wherein said discharge pipe is provided above said introduction pipe.
- 9. A vibration driven motor, comprising:
- a vibration member for generating a vibration therein in response to an electrical signal applied thereto;
- a contact member provided in contact with the vibration member for receiving the vibration;
- a cooling medium introduction pipe;
- a cooling medium discharge pipe;
- a seal member for sealing the vibration member and the contact member, the seal member having a hole formed in a side thereof to mount said cooling medium introduction pipe and to mount said cooling medium discharge pipe; and
- a cover member for covering at least the introduction pipe and discharge pipe.
