Abstract
A one-way clutch includes one or more annular members and one or more annular elastic bodies. The annular member is attached to a side plate of an outer race in the axial outer side of a seal member and includes a facing surface that faces an outer circumferential surface of an inner race with a gap and a recess formed in the facing surface. The annular elastic body is fitted into the outer circumferential surface of the inner surface corresponding to the recess so as to be in close contact therewith.
Claims8
A one way-clutch comprising:
- an inner race and an outer race being coaxially disposed to be relatively rotatable with respect to each other;
- a plurality of cams between the inner race and the outer race being configured to engage with the inner race and the outer race during the rotation of the inner race or the outer race in one direction and not to engage with the inner race and the outer race during the rotation of the inner race or the outer race in another direction;
- and
- a seal member being disposed in the axial outer side of the cams and contacting with an outer circumferential surface of the inner race;
- an annular member being disposed on the outer race and including a facing surface that faces the outer circumferential surface in the axial outer side of the seal member with a gap and a recess being formed in the facing surface;
- and
- an annular elastic body being fitted onto the outer circumferential surface corresponding to the recess so as to be in contact therewith,
- wherein the dimension of the gap is smaller than the radial dimension of the annular elastic body;
- wherein a clearance is provided between the recess and the annular elastic body at least in the radial direction;
- and
- wherein a space in the axial direction is provided between the seal member and the annular member.
