Abstract

A one-way clutch unit for a fishing reel is disclosed. The one-way clutch is configured to brake a rotation of a shaft member of the fishing reel. The one-way clutch includes a rolling element and an outer member. The rolling element contacts the shaft member in a radial direction away from an axle of the shaft member. The outer member is disposed outside the rolling element in the radial direction. The outer member is configured to rotate in only one direction along a circumferential direction around the axle. The outer member includes a first external force receiving portion that receives a first external force in an axial direction of the shaft member.

First claim

What is claimed is:

1. A one-way clutch unit for a fishing reel configured to brake a rotation of a shaft member of the fishing reel, the one-way clutch comprising:
a rolling element that contacts the shaft member in a radial direction away from an axle of the shaft member; and
an outer member disposed outside the rolling element in the radial direction and configured to rotate in only one direction along a circumferential direction around the axle,
the outer member including a first external force receiving portion that receives a first external force in an axial direction of the shaft member, the first external force receiving portion having a first convex portion protruding in the axial direction.

2. The one-way clutch unit for a fishing reel according to claim 1 , wherein
the outer member further includes a retaining portion and a holder, the retaining portion disposed outside the rolling element in the radial direction and configured to retain the rolling element, the holder disposed on the retaining portion and configured to rotate integrally with the retaining portion, and
the first convex portion is disposed on the holder.

3. The one-way clutch unit for a fishing reel according to claim 2 , wherein
the holder includes a first holder and a second holder, the first holder disposed on the retaining portion to cover an end of the shaft member, the second holder disposed on the retaining portion on an opposite side of the first holder in the axial direction.

4. The one-way clutch unit for a fishing reel according to claim 3 , wherein
the first holder and the second holder are bonded or press-fitted to the retaining portion.

5. The one-way clutch unit for a fishing reel according to claim 3 , wherein
the first holder and the second holder are screwed with each other to hold the retaining portion therebetween.

6. The one-way clutch unit for a fishing reel according to claim 3 , wherein
the first holder and the second holder are configured to hold the retaining portion in a state where the retaining portion is disposed radially inside the first holder and the second holder.

7. The one-way clutch unit for a fishing reel according to claim 1 , wherein
the first convex portion is disposed such that the axle of the shaft member extends through the first convex portion.

8. The one-way clutch unit for a fishing reel according to claim 1 , wherein
the first external force receiving portion has an annular second convex portion protruding in the axial direction.

9. The one-way clutch unit for a fishing reel according to claim 1 , wherein
the outer member further includes a second external force receiving portion that receives a second external force acting in a direction opposite to the first external force.

10. The one-way clutch unit for a fishing reel according to claim 1 , wherein
the outer member further includes a second external force receiving portion that receives a second external force acting in a direction opposite to the first external force, and
a radial dimension of the first external force receiving portion is smaller than a radial dimension of the second external force receiving portion.

11. A fishing reel comprising:
a reel body;
a shaft member configured to rotate with respect to the reel body; and
the one-way clutch unit according to claim 1 , installed in the reel body and configured to brake a rotation of the shaft member.

12. The fishing reel according to claim 11 , wherein
the shaft member has a projection,
the outer member has a retaining portion and a holder, the retaining portion disposed outside the rolling element in the radial direction away from the axle of the shaft member and configured to retain the rolling element, the holder disposed on the retaining portion and configured to rotate integrally with the retaining portion,
the holder includes a first holder and a second holder, the first holder disposed on the retaining portion to cover an end of the shaft member, the second holder disposed on the retaining portion on an opposite side of the first holder in the axial direction of the shaft member, and
the second holder has a recess to engage with the projection.

13. The fishing reel according to claim 11 , further comprising:
a friction plate that contacts the first external force receiving portion, wherein
the first external force receiving portion receives the first external force acting thereon by the friction plate.
