Abstract

A spinning reel that forwardly releases a fishing line includes a reel unit, a handle, a drive shaft, a joint structure, and a rotation transmission mechanism. The handle includes a handle shaft and a handle arm, the handle shaft is rotatably supported by the reel unit at a first position, and the handle arm is mounted to the handle shaft and is unitarily rotatable with the handle shaft. The handle arm extends in a radial direction from a rotational axis of the handle shaft. The drive shaft includes a first end and a second end disposed opposite to the first end, and is rotatably supported by the reel unit at a second position different from the first position. The joint structure joins the handle shaft and the drive shaft, and the handle shaft is unitarily rotatable with the drive shaft.

First claim

What is claimed is:

1. A spinning reel that forwardly releases a fishing line, the spinning reel comprising:
a reel unit;
a handle including a handle shaft and a handle arm, the handle shaft rotatably supported by the reel unit at a first position, the handle arm mounted to the handle shaft and unitarily rotatable with the handle shaft, the handle arm extending in a radial direction from a rotational axis of the handle shaft;
a drive shaft including a first end and a second end located opposite to the first end, the drive shaft rotatably supported by the reel unit at a second position different from the first position;
a joint structure joining the handle shaft and the drive shaft such that the handle shaft is unitarily rotatable with the drive shaft; and
a rotation transmission mechanism including a drive gear and a pinion gear, the drive gear mounted to the drive shaft and unitarily rotatable with the drive shaft, the pinion gear disposed in a back-and-forth direction so as to be skew to the drive shaft, the pinion gear being meshed with the drive gear, wherein
the joint structure includes
a recess on one of the handle shaft and the drive shaft, and
a protrusion on the other of the handle shaft and the drive shaft, the protrusion engaged with the recess and unitarily rotatable with the recess.

2. The spinning reel according to claim 1 , wherein the joint structure detachably joins the handle shaft and the drive shaft to each other in an axial direction parallel to the rotational axis of the handle shaft.

3. The spinning reel according to claim 1 , wherein
the reel unit includes
a first body including a first bearing supporting the first end of the drive shaft such that the first end is rotatable, the first body supporting the pinion gear such that the pinion gear is rotatable, and
a second body including a second bearing supporting the second end of the drive shaft such that the second end is rotatable, and

the rotation transmission mechanism is in a mechanism mount space between the first body and the second body.

4. The spinning reel according to claim 3 , wherein
the first body includes a first drive shaft support part to which the first bearing is mounted,
the second body includes a second drive shaft support part to which the second bearing is mounted, and
the reel unit further includes a handle shaft support portion and at least one third bearing, the handle shaft support portion being away from one of the first drive shaft support part and the second drive shaft support part in an axial direction parallel to the rotational axis of the handle shaft, the at least one third bearing mounted to the handle shaft support portion, the at least one third bearing supporting the handle shaft such that the handle shaft is rotatable.

5. The spinning reel according to claim 4 , wherein the reel unit further includes a cover member, the handle shaft support portion is disposed on one of the first body or the second body, and
the cover member covers an outer lateral surface of the first or second body to which the at least one third bearing is not mounted.

6. The spinning reel according to claim 5 , wherein the handle shaft support portion is permanently mounted to at least one of the first body and the second body.

7. The spinning reel according to claim 6 , wherein
the reel unit further includes a retainer member, the retainer member having a mount structure detachably mountable to one of the first body and the second body, the retainer member retaining the at least one third bearing, and
the cover member is detachably mountable to the other of the first body and the second body by a mount structure.

8. The spinning reel according to claim 5 , wherein the handle shaft support portion is detachably mountable to one of the first body and the second body.

9. The spinning reel according to claim 8 , wherein the cover member is detachably mountable to the other of the first body and the second body by a mount structure.

10. The spinning reel according to claim 4 , wherein the reel unit further includes mounting means for interchangeably mounting a cover member and the handle shaft support portion to the reel unit.

11. The spinning reel according to claim 1 , wherein the recess and the protrusion are engaged by a non-circular engagement.

12. The spinning reel according to claim 1 , wherein
the recess is recessed on the drive shaft along an axial direction parallel to the rotational axis of the handle shaft, and
the protrusion protrudes from the handle shaft along the axial direction.

13. The spinning reel according to claim 12 , wherein
the drive shaft includes a support hole, the support hole having a circular shape, the support hole opened in the recess, and
the handle shaft includes a supported part, the supported part having a circular shape, the supported part extending from the protrusion in the axial direction, the supported part fitted to the support hole.

14. The spinning reel according to claim 13 , wherein the supported part includes a relief part and a fitting part, the relief part extending from the protrusion in the axial direction, the relief part separated by a gap from the support hole, the fitting part having a larger diameter than the relief part, the fitting part contacting the support hole.

15. The spinning reel according to claim 14 , wherein the fitting part is elastically fitted to the support hole.

16. The spinning reel according to claim 1 , further comprising:
a spool for winding the fishing line, the spool supported by the reel unit to be movable back and forth; and
a rotor coupled to the pinion gear to be unitarily rotatable with the pinion gear at least in a fishing line winding direction, the rotor to wind the fishing line about the spool.

17. A spinning reel for forwardly releasing a fishing line, the spinning reel comprising:
a handle including a handle shaft and a handle arm, the handle arm mounted to the handle shaft and unitarily rotatable with the handle shaft, the handle arm extending in a radial direction from a rotational axis of the handle shaft;
a drive shaft unitarily rotatable with the handle shaft;
joining means for joining the handle shaft and the drive shaft; and
