Abstract

A one-way clutch of the present disclosure comprises an inner ring, an outer ring, and a holder comprising a holding portion holding a biasing spring for biasing a plurality of rolling members. The holder comprises a first holder provided with the holding portion, and a second holder attached to the first holder so as to hold the outer ring in an axial direction. The first holder and the second holder are integrated by an engagement fixing portion provided on a radially inner side of an inner circumferential contour of the outer ring.

First claim

What is claimed is:

1. A one-way clutch comprising an inner ring, an outer ring, and a holder comprising a holding portion holding a biasing spring for biasing a plurality of rolling members, wherein
the holder comprises a first holder provided with the holding portion, and a second holder attached to the first holder so as to hold the outer ring in an axial direction,
the first holder and the second holder are integrated by an engagement fixing portion provided on a radially inner side of an inner circumferential contour of the outer ring, and
the engagement fixing portion has a displacement portion that is elastically displaced when the first holder and the second holder are moved relatively in the axial direction and comprises a locking claw, and a retaining portion that retains the locking claw of the displacement portion.

2. The one-way clutch according to claim 1 , wherein
the displacement portion is formed integrally with the holding portion of the first holder, and
the retaining portion is a fitting hole which is formed in the second holder and to which the locking claw of the displacement portion is locked.

3. The one-way clutch according to claim 1 , wherein
a plurality of engagement fixing portions are provided in the first holder and the second holder.

4. The one-way clutch according to claim 1 , wherein
the engagement fixing portion integrally fixes the first holder and the second holder by welding, caulking, or screwing.

5. A fishing reel incorporating a one-way clutch that allows rotation of a rotation drive shaft supported in a reel body in one direction and prevents rotation in the other direction, wherein
the one-way clutch comprises an inner ring, an outer ring, and a holder comprising a holding portion holding a biasing spring for biasing a plurality of rolling members,
the holder comprises a first holder provided with the holding portion, and a second holder attached to the first holder so as to hold the outer ring in the axial direction,
the first holder and the second holder are integrated by an engagement fixing portion provided on a radially inner side of an inner circumferential contour of the outer ring, and
the engagement fixing portion has a displacement portion that is elastically displaced when the first holder and the second holder are moved relatively in the axial direction and comprises a locking claw, and a retaining portion that retains the locking claw of the displacement portion.

6. The fishing reel according to claim 5 , wherein
the reel body is provided with a regulation portion that is fixed so as to regulate the movement of the one-way clutch in a rotation direction,
the first holder and the outer ring are respectively provided with stoppers that protrude radially outward, and
the movement of the one-way clutch in the rotation direction is regulated by the regulation portion provided on the reel body and each stopper.

7. The fishing reel according to claim 6 , wherein
the regulation portion is a notch portion which is formed along a circumferential direction on a circumferential wall provided in the reel body and in which the stopper is disposed.
