A lens,
A vibration type linear actuator that includes a vibration member in which vibration is excited by an electro-mechanical energy conversion action and a contact member in pressure contact with the vibration member, and drives the lens in the optical axis direction;
Wherein one of the members of the vibration member and the contact member, in the direction of the straight interlinks the second axis to the rotation and the contact surfaces of the flat line a first axis to the pressure contact surface of one member the A first holding mechanism for holding the movable body so as to be movable;
The other member of said vibration member and said contact member, flat row to the pressure contact surface of said other member, and allows rotation of the third axis extending in a straight direction orthogonal to said first axis And a second holding mechanism for holding the optical device.   The first holding mechanism is provided in a lens holding member that holds the lens and moves in the optical axis direction, and the second holding mechanism is provided in a fixing portion of the optical apparatus. The optical apparatus according to claim 1. It said first axis, optical apparatus according to claim 1 or 2, characterized in that the axis included directly in the exchange that plane to the optical axis.   The first holding mechanism moves the one member in the direction of the second axis via a rotation member that is rotatable around a position away from the one member in the direction of the first axis. The optical apparatus according to any one of claims 1 to 3, wherein the optical apparatus is held so as to be movable.   5. The optical apparatus according to claim 1, wherein the third axis is an axis included in a pressure contact surface of the other member.   6. The optical apparatus according to claim 1, wherein the first axis is an axis included in a pressure contact surface of the one member.   The optical apparatus according to any one of claims 1 to 6, wherein the second holding mechanism rotatably holds the other member by a spherical member.   The first and second holding mechanisms allow rotation and movement of the one member and the other member by receiving a force smaller than a pressure contact force between the vibration member and the contact member. Item 8. The optical apparatus according to any one of Items 1 to 7. A lens,
Including a vibration member whose vibration is excited by an electro-mechanical energy conversion action and a contact member in pressure contact with the vibration member, and a vibration type linear actuator that drives the lens in the optical axis direction,
An optical apparatus comprising: a holding mechanism that holds one member of the vibrating member and the contact member so as to be rotatable around an axis included in a pressure contact surface of the one member.   The optical apparatus according to claim 9, wherein the holding mechanism holds the one member rotatably by a spherical member. The other member of said contact member and said vibrating member, the other holding mechanism for holding through a rotatable pivot member about a position apart straight direction orthogonal to said axis from said other member The optical apparatus according to claim 9 or 10, characterized by comprising: The other retaining mechanism holds said other member of the vibration member and the contact member, as included in the press-contact surface of said other member, a rotatable linear interlinking axis to said shaft The optical apparatus according to claim 11, wherein:
