Abstract
A vibration wave driven apparatus disclosed in this specification frictionally drives a first member having mounted thereon an elastic member in which a travelling vibration wave is formed and a second member provided with a rail-like stator which is in pressure contact with the elastic member, along the lengthwise direction of the rail-like stator, by the travelling vibration wave formed in the elastic member. Further, the apparatus has a guide member for restraining the degree of freedom in a direction orthogonal to the lengthwise direction, the guide member being comprised of a roller and a guide portion against which the roller bears and which extends along the direction of relative movement.
Claims8
A vibration driven motor, comprising:
- a vibration member responsive to an applied electrical signal for generating a vibration therein;
- a contact member which is in contact with said vibration member, the vibration generated in said vibration member effecting relative movement between said vibration member and said contact member;
- a support member for movably supporting one of said vibration member or said contact member;
- a first and second roller arrangements functionally engaged with said support member;
- a first guide member in contact with said first roller arrangement, said first guide member preventing said first roller arrangement from sliding in a horizontal direction;
- and
- a second guide member in contact with said second roller arrangement, said second guide member preventing said second roller arrangement from sliding in a vertical direction.
