Abstract

An oscillating mechanism for a spinning reel that moves a spool shaft in a spool shaft direction in conjunction with a rotation of a handle shaft includes a sliding gear, a cam gear and a slider. The sliding gear rotates in conjunction with the rotation of the handle shaft. The cam gear has a gear portion formed from metal that includes a gear body configured to mesh with the sliding gear and a boss protruding from the gear body, and a resin support portion supporting a radially inward side of the gear portion and configured to rotate integrally with the gear portion. The slider is mounted on the spool shaft and includes an engagement groove in which the boss is configured to engage and which is configured to move the spool shaft in the spool shaft direction by moving the boss along the engagement groove.

Claims (31)

1 . An oscillating mechanism for a spinning reel that moves a spool shaft in a spool shaft direction in conjunction with a rotation of a handle shaft, comprising:

a sliding gear configured to rotate in conjunction with the rotation of the handle shaft;

a cam gear having a gear portion formed from metal that includes a gear body configured to mesh with the sliding gear and a boss protruding from the gear body, and a resin support portion supporting a radially inward side of the gear portion and configured to rotate integrally with the gear portion; and

a slider mounted on the spool shaft and including an engagement groove in which the boss is configured to engage and which is configured to move the spool shaft in the spool shaft direction by moving the boss along the engagement groove,

the gear portion including a first engagement part configured to engage the support portion and the boss extending from the first engagement part in an axial direction of the cam gear.

2 . The oscillating mechanism for a spinning reel according to claim 1 , wherein

the gear portion includes zinc.

3 . The oscillating mechanism for a spinning reel according to claim 1 , wherein

the support portion includes a polyoxymethylene resin or a polyacetal resin.

4 . A spinning reel, comprising:

the oscillating mechanism according to claim 1 ;

a reel body;

the spool shaft supported so as to be movable in a front-rear direction with respect to the reel body; and

the handle shaft supported so as to be rotatable with respect to the reel body.

5 . An oscillating mechanism for a spinning reel that moves a spool shaft in a spool shaft direction in conjunction with a rotation of a handle shaft, comprising:

a sliding gear configured to rotate in conjunction with the rotation of the handle shaft:

a cam gear having a gear portion formed from metal that includes a gear body configured to mesh with the sliding gear and a boss protruding from the gear body, and a resin support portion supporting a radially inward side of the gear portion and configured to rotate integrally with the gear portion; and

a slider mounted on the spool shaft and including an engagement groove in which the boss is configured to engage and which is configured to move the spool shaft in the spool shaft direction by moving the boss along the engagement groove,

the gear portion including a first engagement part protruding radially inwardly from the gear body, and

the support portion including a first concave part that opens radially outwardly and with which the first engagement part is configured to engage.

6 . The oscillating mechanism for a spinning reel according to claim 5 , wherein

the boss protrudes from the first engagement part in an axial direction of the cam gear.

7 . The oscillating mechanism for a spinning reel according to claim 5 , wherein

the support portion has a body portion disposed on the radially inward side of the gear portion and supporting the gear portion, and a flange extending radially outwardly from the body portion and disposed on an outer side surface of the gear portion in an axial direction, and

the first concave part is disposed on the body portion and the flange.

8 . The oscillating mechanism for a spinning reel according to claim 5 , wherein

the gear portion includes a first engagement part protruding radially inwardly from the gear body, and

the support portion includes a second concave part opening radially outwardly and with which a second engagement part is configured to engage.

9 . The oscillating mechanism for a spinning reel according to claim 8 , wherein

the support portion has a body portion disposed on the radially inward side of the gear portion and supporting the gear portion, and a flange extending radially outwardly from the body portion and disposed on an outer side surface of the gear portion in an axial direction, and

the second concave part is disposed on the body portion.
