The second support portion 12b is fixed to the second side plate main body portion 12a. The second support portion 12b comprises the second guide groove 17 described above.
As shown in FIG. 3 and FIG. 4, the first guide groove 16 and the second guide groove 17 are formed to have a circular arc shape with a rotational axis as the center. The radius of the first guide groove 16 is smaller than the radius of the second guide groove 17. In particular, the radius of the outer peripheral edge of the first guide groove 16 is smaller than the radius of the outer peripheral edge of the second guide groove 17. For example, the radius of the outer peripheral edge of the first guide groove 16 is about equal to or greater than 23.5 mm and equal to or less than 25.0 mm. The radius of the outer peripheral edge of the second guide groove 17 is about equal to or greater than 24.5 mm and equal to or less than 26.0 mm.
The length of the first guide groove 16 is shorter than the length of the second guide groove 17.

The length of the second guide groove 17 is about equal to or greater than 16.0 mm and equal to or less than 18.0 mm. The width of the first guide groove 16 is smaller than the width of the second guide groove 17. For example, the width of the first guide groove 16 is about equal to or greater than 1.5 mm and equal to or less than 2.0 mm. The width of the second guide groove 17 is about equal to or greater than 2.2 mm and equal to or less than 2.8 mm. Here, the widths of the first and second guide grooves 16 and 17 represent the length of each guide groove in the radial direction.
FIG. 5 is a side view of the dual-bearing reel, as viewed from the first side. As shown in FIG. 5, the first side plate 11 and the second side plate 12 are substantially circular from the side view. The radius of the first side plate 11 is smaller than the radius of the second side plate 12.
As shown in FIG. 1, the handle 3 is configured to rotate the spool 2. Specifically, the handle 3 is rotatably mounted to the outer side surface on the second side of the reel body 1. The spool 2 is driven via the rotation transmission mechanism 6 by rotating the handle 3. Additionally, a level winding mechanism 7 is driven in parallel by rotating the handle 3.
As shown in FIG. 6, the rotation transmission mechanism 6 is configured to transmit the rotation of the handle 3 to the spool 2. The rotation transmission mechanism 6 is also configured to simultaneously transmit the rotation of the handle 3 to the level winding mechanism 7. The rotation transmission mechanism 6 is installed in a space that is defined by the second side plate 12 and the second side cover 15, as described above. The rotation transmission mechanism 6 comprises a drive shaft 61, a drive gear 62, and a pinion gear 63.
The drive shaft 61 is engaged with the handle 3 and integrally rotates with the handle 3. Meanwhile, the drive shaft 61 is prohibited from rotating in the casting direction by a one-way clutch 64. That is, the drive shaft 61 only rotates in the line winding direction. The drive gear 62 is mounted to the drive shaft 61 and integrally rotates with the drive shaft 61.
FIG. 7 is a cross-sectional view of the dual-bearing reel, as viewed from the front. As shown in FIG. 7, the pinion gear 63 comprises a gear portion 63a that meshes with the drive gear 62. The pinion gear 63 has a tubular shape. A spool shaft 21 extends through the center of the pinion gear 63. The pinion gear 63 is rotatably supported by the reel body 1. In particular, the pinion gear 63 is supported by the second side plate 12 and the second side cover 15 via an axle bearing member.
The pinion gear 63 is mounted to the spool shaft 21 so as to be slidable in the axial direction. The pinion gear 63 comprises an engagement portion 63b. The engagement portion 63b is configured to engage an engagement pin 211a of the spool shaft 21. Specifically, the engagement portion 63b is formed from a plurality of notched portions configured to engage the engagement pin 21a. The engagement pin 21a is configured to protrude radially from the outer peripheral surface of the spool shaft 21.
The clutch mechanism 4 is configured to engage or disengage the handle 3 and the spool 2. Specifically, the above-described engagement portion 63b and engagement pin 21a configure the clutch mechanism 4. When the pinion gear 63 moves to the first side in the axial direction, the engagement portion 63b and the engagement pin 21a are engaged. The handle 3 and the spool 2 are thereby engaged. That is, the rotation of the handle 3 and the rotation of the spool 2 are linked. On the other hand, when the pinion gear 63 moves to the second side in the axial direction, the engagement between the engagement portion 63b and the engagement pin 21a is disengaged. The handle 3 and the spool 2 are thereby disengaged. That is, the rotation of the handle 3 and the rotation of the spool 2 are not linked. For example, even when the spool 2 is rotated when casting, the handle 3 will not rotate.
The spool 2 is configured to rotate around a rotational axis. Specifically, the spool 2 is fixed to a spool shaft 21 and integrally rotates with the spool shaft 21. The center axis O of this spool shaft 21 corresponds to the rotational axis.
The spool 2 is disposed between the first side plate 11 and the second side plate 12. Fishing line is wound on the outer peripheral surface of the spool 2. The spool shaft 21 extends between the first side plate 11 and the second side plate 12. The spool shaft 21 is rotatably supported by the reel body 1 via an axle bearing member, etc. For example, the first side end of the spool shaft 21 is rotatably supported by a support member 22 that is fixed to the first side plate 11 via an axle bearing member 23. Meanwhile, the axle bearing member 23 is fixed to the support member 22. The second side end of the spool shaft 21 is rotatably supported by the second side cover 15 via an axle bearing member 24.
The clutch operating member 5 is configured to operate the clutch mechanism 4. In particular, the clutch operating member 5 comprises a clutch plate 51, as shown in FIG. 8. The clutch operating member 5 further comprises a clutch cam 52, a retainer plate 53, a clutch yoke 54, and a cover member 56.
As shown in FIG. 9, the clutch plate 51 comprises a main body portion 51a, a first side end 51b, and a stepped portion 51c. The clutch plate 51 further comprises a mounting portion 51d. The main body portion 51a, the first side end 51b, the stepped portion 51c, and the mounting portion 51d are formed by a single member. For example, the clutch plate 51 is made of metal.
The main body portion 51a extends along the axial direction between the first side plate 11 and the second side plate 12. The main body portion 51a is slidably supported by the second guide groove 17. Specifically, a second side end 511a of the main body portion 51a is slidably supported by the second guide groove 17. The main body portion 51a slides in the circumferential direction. The main body portion 51a has a rectangular shape.
The first side end 51b extends along the axial direction and is disposed to be closer to the rotational axis O than to the main body portion 51a. The first side end 51b is slidably supported by the first guide groove 16. The first side end 51b slides in the circumferential direction.
The width wb of the first side end 51b is smaller than the width wa of the main body portion 51a, as shown in FIG. 10. Meanwhile, the width wa of the main body portion 51a and the width wb of the first side end 51b represent the lengths in the direction that is perpendicular to the longitudinal direction of the main body portion 51a. In other words, the width wa of the main body portion 51a and the width wb of the first side end 51b represent the lengths extending substantially along the tangential direction of the circumference. For example, the width wb of the first side end 51b is about equal to or greater than 2 mm and equal to or less than 5 mm. The width wa of the main body portion 51a is about equal to or greater than 5 mm and equal to or less than 8 mm.
As shown in FIG. 9, the stepped portion 51c is disposed between the main body portion 51a and the first side end 51b. Specifically, the stepped portion 51c extends in the radial direction. The radially inner end 511c of the stepped portion 51c is engaged to the first side end 51b. The radially outer end 512c of the stepped portion 51c is engaged to the main body portion 51a. 
Since a stepped portion 51c is disposed between the main body portion 51a and the first side end 51b in this manner, the first side end 51b is in a position that is closer to the rotational axis O in the radial direction than to the main body portion 51a. That is, the turning radius of the first side end 51b is smaller than the turning radius of the main body portion 51a. The main body portion 51a, the first side end 51b, and the stepped portion 51c are disposed behind the spool 2.
The mounting portion 51d is a portion that is mounted to the reel body 1. As shown in FIG. 8, the mounting portion 51d is rotatably mounted to the reel body 1. Specifically, the mounting portion 51d is mounted to an attaching plate 18. The attaching plate 18 is fixed to the second side plate 12. The attaching plate 18 comprises a boss portion 18a. The boss portion 18a has a cylindrical shape and protrudes toward the second side in the axial direction. The mounting portion 51d comprises an opening in the center portion. The mounting portion 51d is rotatably mounted to the boss portion 18a, with the boss portion 18a being inserted in the opening 51e of this mounting portion 51d. 
The clutch cam 52 rotates in conjunction with the clutch plate 51. The clutch cam 52 is disposed to rotate about the rotational axis O. The clutch cam 52 is rotatably attached to the attaching plate 18. Specifically, the clutch cam 52 comprises an opening in the center portion. The clutch cam 52 is rotatably mounted to the boss portion 18a, with the boss portion 18a of the attaching plate 18 being inserted in this opening.
The clutch cam 52 comprises a cam surface 52a and a protrusion 52b. The cam surface 52a is configured to press the clutch yoke 54 to the second side in the axial direction via the retainer plate 53. Specifically, when the clutch cam 52 is rotated counterclockwise, when viewed from the second side in the axial direction, the cam surface 52a presses the clutch yoke 54 to the second side in the axial direction, and the clutch yoke 54 moves to the second side in the axial direction. The clutch cam 52 is, for example, made of a synthetic resin.
The protrusion 52b is a portion that protrudes radially outward and a portion to which a return member 55 mentioned below is mounted. The clutch cam 52 further comprises an engagement protrusion (not shown). The engagement protrusion protrudes to the first side in the axial direction. This engagement protrusion engages an engagement hole 51f of the clutch plate 51. With this engagement, the clutch plate 51 and the clutch cam 52 integrally rotate about the rotational axis O.
The clutch yoke 54 comprises an engagement portion 54b. The clutch yoke 54 is pressed to the second side in the axial direction with the cam surface 52a engaging the engagement portion 54b of the clutch yoke 54. The clutch yoke 54 is movably supported by the retainer plate 53 in the axial direction. The retainer plate 53 is disposed in each opening of the clutch plate 51 and the clutch cam 52. Additionally, the retainer plate 53 is fixed to the attaching plate 18.
The retainer plate 53 comprises a plurality of pins 53a that extend in the axial direction. Each pin 53a extends to the second side in the axial direction. The clutch yoke 54 comprises a through-hole 54a in a position corresponding to each pin 53a. The clutch yoke 54 is movably supported in the axial direction, with each pin 53a being inserted in each through-hole 54a. 
The clutch yoke 54 is configured so as to engage with a constricted portion 63c of the pinion gear 63. For this reason, the pinion gear 63 moves in the axial direction in conjunction with the clutch yoke 54. Meanwhile, the configuration is such that the clutch yoke 54 will not rotate even if the pinion gear 63 rotates. The clutch yoke 54 is biased to the first side in the axial direction by a biasing member. Specifically, a plurality of coil springs 53b supported by the pins 53a of the retainer plate 53 biases the clutch yoke 54 to the first side in the axial direction.
In a normal state, the clutch yoke 54 is biased to the first side in the axial direction by each coil spring 53b. For this reason, the engagement portion 63b of the pinion gear 63 engages the engagement pin 21a of the spool shaft 21. That is, the clutch mechanism 4 engages the handle 3 and the spool 2. In contrast, when the clutch yoke 54 moves to the second side in the axial direction by operating the clutch plate 51, the engagement between the engagement portion 63b of the pinion gear 63 and the engagement pin 21a is disengaged. As a result, the clutch mechanism 4 disengages the handle 3 and the spool 2.
The return member 55 is pivotally mounted to the protrusion 52b of the clutch cam 52. The return member 55 comprises a pawl portion. The pawl portion abuts the outer peripheral part of a ratchet wheel (not shown) that integrally rotates with the drive shaft 61. The return member 55 is biased in both directions of the pivoting direction by a toggle spring 55a. The clutch cam 52 moves to the first side in the axial direction with the pawl portion of the return member 55 being pressed by the rotation of the ratchet wheel. In other words, the clutch cam 52 returns from a clutch-off position to a clutch-on position.
FIG. 11 is a perspective view of a cover member 56 in a state of attachment to the clutch plate 51. FIG. 12 is a perspective view of the cover member 56 in a state of detachment from the clutch plate 51. As shown in FIG. 11, the cover member 56 is attached to the main body portion 51a of the clutch plate 51.
As shown in FIG. 12, the cover member 56 comprises an attaching portion 56a and a cover portion 56b. An insertion groove 561a that extends in the axial direction is formed in the attaching portion 56a. The main body portion 511a of the clutch plate 51 is inserted in this insertion groove 561a. Additionally, an engagement groove 562a is formed in the attaching portion 56a. The engagement groove 562a communicates with the insertion groove 561a. 
FIG. 13 is a perspective view of a cover portion 56b. As shown in FIG. 13, the cover portion 56b comprises a protrusion 561b. The protrusion 561b fits into the engagement groove 562a (refer to FIG. 12). The protrusion 561b comprises a shoulder portion 561c. When attaching the cover portion 56b to the attaching portion 56a, the movement of the protrusion 561b upwards is restricted by this shoulder portion 561c. As shown in FIG. 11, the main body portion 51a of the clutch plate 51 is inserted in the insertion groove 561a after attaching the cover portion 56b to the attaching portion 56a. Then, the cover member 56 is screwed to the main body portion 51a of the clutch plate 51 with a bolt 57. With this configuration, the cover portion 56b is securely fixed to the attaching portion 56a. 
Characteristics
The dual-bearing reel 100 according to the present embodiment has the following characteristics.
The first side end 51b of the clutch plate 51 is disposed so as to be closer to the rotational axis O than to the main body portion 51a. For this reason, the turning radius of the first side end 51b is smaller than the turning radius of the main body portion 51a when the clutch plate 51 rotates about the rotational axis O in order to operate the clutch mechanism 4. Therefore, it is possible to dispose the first guide groove 16, which holds the first side end 51b, closer to the rotational axis O than to the second guide groove 17. In other words, the radius of the outer peripheral edge of the first guide groove 16 can be made to be smaller than the radius of the outer peripheral edge of the second guide groove 17. As a result, in the present embodiment, it is possible to make the first side plate 11 smaller than the second side plate 12 by around 3-8 mm, improving the reel fit while palming.
