摘要:
A vibration type motor includes a limiter configured to limit a distance between a movable guide member and a fixed guide member. The limiter has first, second, and third limiting areas. The first limiting area is disposed between a first roll member and a second roll member in one direction. The second limiting area is disposed on the same side as the second roll member with respect to the first roll member and distant from the second roll member in the one direction. The third limiting area is disposed on an opposite side of the second roll member with respect to the first roll member in the one direction. A length of the first limiting area in another direction orthogonal to the one direction is equal to or longer than that of each of the second limiting area and the third limiting area in the one direction.
