Abstract
A power transmission device includes: a first rotation member; a first rotation shaft supporting the first rotation member; a second rotation member; a second rotation shaft supporting the second rotation member; and an endless flexible member wound around the first rotation member and the second rotation member, in which at least one of the first rotation member and the second rotation member is movable in an axial direction thereof, and the endless flexible member includes a restriction portion configured to restrict movement of at least one of the first rotation member and the second rotation member in the axial direction.
Claims8
A power transmission device comprising:
- a first rotation member;
- a first rotation shaft supporting the first rotation member;
- a second rotation member;
- a second rotation shaft supporting the second rotation member;
- and
- an endless flexible member wound around the first rotation member and the second rotation member, wherein
- at least one of the first rotation member and the second rotation member is movable in an axial direction thereof,
- the endless flexible member includes a restriction portion configured to restrict movement of at least one of the first rotation member and the second rotation member in the axial direction,
- the first rotation member is fixed to the first rotation shaft in a manner that does not allow rotation relative to the first rotation shaft and does not allow movement in the axial direction relative to the first rotation shaft, and
- the second rotation member is fixed to the second rotation shaft in a manner that does not allow rotation relative to the second rotation shaft and does not allow movement in the axial direction relative to the second rotation shaft.
