Next, details of the body 10, the protective cover 40, the spool reciprocating device 70, and the lid member 30 will be described.

As shown in FIGS. 3 and 4, the body 10 has a bottomed box shape (cylindrical shape) and opens toward the left side. The body 10 is a member that accommodates and supports the winding drive device (the handle shaft 5, the drive gear 6, the drive shaft tube 7, etc.) inside. The body 10 includes a disk-shaped right wall portion 22 and a tubular tubular portion 21 extending leftward from the peripheral edge of the right wall portion 22 . A left end portion of the tubular portion 21 constitutes the side opening portion 13 . A helical female screw portion 21b (see FIG. 6) is formed on the inner peripheral surface 21a of the tubular portion 21 . A contact surface 21c is formed on the left side of the inner peripheral surface 21a, on which the female threaded portion 21b is not formed.

As shown in FIG. 6, the body 10 is formed with a mounting hole 81 penetrating inwardly and outwardly toward the rotor 2 side. The drive shaft tube 7 (pinion gear 7a) is inserted through the mounting hole 81 via a bearing 82 (see FIG. 4). The inner diameter of the mounting hole portion 81 is sufficiently larger than the outer diameter of the drive shaft cylinder 7 (pinion gear 7a). A deformed portion 91 is formed in a part of the mounting hole portion 81 . Details of the deformed portion 91 will be described later.

As shown in FIG. 4, a right central hole 23, a rib 24 (see FIG. 3), and an insertion hole 25 are formed in the inner surface (left side surface) of the right wall portion 22. As shown in FIG. The right central hole 23 is a hole through which the right end portion of the handle shaft 5 passes, and is provided in the central portion of the right wall portion 22 .

As shown in FIG. 3, the rib 24 is a protrusion that extends in the up-down direction and is positioned forward of the right central hole 23 (see FIG. 4). This rib 24 improves the strength of the right wall portion 22 . A guide shaft support hole 24 a for supporting the front end 71 a of the guide shaft 71 is formed in the upper portion of the rib 24 . On the other hand, a through hole 24b is formed in the lower portion of the rib 24 for allowing the rear portion 8a of the spool shaft 8 to pass therethrough rearward. A collar 8c (see FIG. 4) that supports the rear end of the drive shaft cylinder 7 is fitted in the through hole 24b.

As shown in FIG. 4 , the insertion hole 25 is formed behind the right central hole 23 . A boss portion 27 of a support member 26 provided on the outside (right side) of the right wall portion 22 passes through the insertion hole 25 . As a result, the boss portion 27 that rotatably supports the interlocking gear 74 is arranged at the rear portion within the body 10 .

As shown in FIG. 3, the cylindrical portion 21 has a substantially cylindrical shape centered on the central axis O1 of the handle shaft 5. As shown in FIG. More specifically, the inner peripheral surface 21 a of the tubular portion 21 is formed in a circular shape centered on the central axis O1 of the handle shaft 5 and corresponds to the size of the drive gear 6 .

The outer peripheral surface 21g of the cylindrical portion 21 is formed in a substantially circular shape centered on the central axis O1 of the handle shaft 5, and the thickness (thickness in the radial direction) of the cylindrical portion 21 is substantially uniform in the circumferential direction. there is Therefore, the cylindrical portion 21 is miniaturized so that no unnecessary space is generated between the inner peripheral surface 21 a of the cylindrical portion 21 and the drive gear 6 . The left end (the side opening 13 ) of the inner peripheral surface 21 a of the cylindrical portion 21 is designed so that even a relatively large drive gear 6 can be easily assembled in the cylindrical portion 21 .

As shown in FIG. 4 , the protective cover 40 is fastened with bolts (not shown) and fixed so as to cover the rear opening 15 of the body 10 . A seal member 50 is provided between the protective cover 40 and the body 10 to prevent water from entering the inside from the mating surfaces of the protective cover 40 and the body 10 .

Next, details of the main configuration of the spool reciprocating device 70 will be described. As shown in FIG. 3, the interlocking gear 74 is attached to the body 10 from the rear so as to pass through the rear opening 15, and a part (rear region) of the interlocking gear 74 protruding rearward from the rear opening 15 is It is housed within the protective cover 40 . The interlocking gear 74 cooperates with the slider 72 via the eccentric protrusion 75 as a converting driving member that converts the rotation of the handle shaft 5 into the forward and backward reciprocating motion of the spool shaft 8 .

A rear end 71 b of the guide shaft 71 is engaged with the engaged portion 41 inside the protective cover 40 , and the guide shaft 71 passes through the rear opening 15 . Therefore, part of the slider 72 enters the protective cover 40 when it moves backward, and the range of movement of the slider 72 is effectively secured.

A recess 72a recessed rearward is formed in the front surface of the slider 72 (the surface facing the handle shaft 5). Therefore, when the slider 72 moves forward, the handle shaft 5 is received in the recess 72a, and the range of movement of the slider 72 is expanded forward. As described above, the movement range (stroke) of the slider 72 is effectively ensured while preventing the body 10 from increasing in size.

Next, details of the deformed portion 91 and the lid member 30 will be described. As shown in FIGS. 6 and 7 , the deformed portion 91 is formed so as to partially fill the hole wall of the mounting hole portion 81 . Although the shape of the deformed portion 91 is not particularly limited, in this embodiment, it is composed of a chord and an arc, so the hole through which the drive shaft tube 7 is inserted has a D shape when viewed along the spool shaft 8 .

An inner surface 91a of the deformed portion 91 is formed with a female thread portion 91b. The female threaded portion 91b is a portion to which the lid member 30 is screwed, and is formed continuously with the female threaded portion 21b provided on the inner peripheral surface 21a of the tubular portion 21 .

A D-shaped mounting hole portion 81 having a smaller diameter than the support hole diameter of the bearing 82 and into which the pinion gear 7a can be inserted is formed by molding or machining. The mounting hole portion 81 having the deformed portion 91 provided with the female thread portion 91b may be a through hole through which the pinion gear 7a can be inserted, and its shape is not limited to the D shape.

As shown in FIG. 2, the lid member 30 is formed in a circular shape. A left center hole 31 through which the left end of the handle shaft 5 passes is formed in the center of the lid member 30 .

As shown in FIG. 4 , the lid member 30 includes a disk-shaped lid main body portion 32 and a peripheral wall portion 33 rising from the peripheral edge of the lid main body portion 32 . As shown in FIG. 5, a flange portion 32a is formed on the outer peripheral edge of the lid body portion 32 so as to slightly protrude sideways in the circumferential direction.

The peripheral wall portion 33 has a cylindrical shape. As shown in FIG. 5, the outer peripheral surface of the peripheral wall portion 33 includes a contact surface 33a formed on the base end side, a male threaded portion 33b formed on the distal end side, and a contact surface 33a and the male threaded portion 33b. and a receiving recess 33c formed therebetween. The contact surface 33 a is a portion that contacts the contact surface 21 c of the cylindrical portion 21 . The housing recess 33c is a portion where a ring-shaped sealing member 35 (for example, an O-ring) is arranged between the contact surface 21c of the cylindrical portion 21 and the housing recess 33c.

As shown in FIG. 5 , the male threaded portion 33 b of the lid member 30 is screwed into the female threaded portion 21 b of the cylindrical portion 21 and the female threaded portion 91 b of the deformed portion 91 . As a result, the side opening 13 (see FIG. 6) is closed by the lid member 30 . When the lid member 30 is fastened to the cylindrical portion 21 (body 10), the tightening is completed when the flange portion 32a of the lid main body portion 32 comes into contact with the stepped portion 21d formed on the inner peripheral surface 21a of the body 10. . When the fastening of the lid member 30 is completed, the distal end of the peripheral wall portion 33 is positioned at the female threaded portion 21b of the cylindrical portion 21 and the female threaded portion 91b of the deformed portion 91 . In other words, the male threaded portion 33b of the lid member 30 is not exposed inside the body 10 when the fastening of the lid member 30 is completed.

Here, if there is no deformed portion 91 shown in FIG. 6 (in the case of the conventional example: see the dashed line in FIG. 7), the male threaded portion 33b of the lid member 30 is screwed into the female threaded portion 21b of the tubular portion 21. Then, the male screw portion 33 b passes through the opening of the mounting hole portion 81 . At this time, foreign matter such as burrs and chips may fall from the opening end of the mounting hole 81 or the male threaded portion 33b to the meshing portion between the drive gear 6 and the pinion gear 7a, resulting in deterioration of rotational performance.

On the other hand, according to the fishing spinning reel 100 according to the present embodiment, since the deformed portion 91 is provided on the hole wall of the mounting hole portion 81 , the external thread portion 33b of the lid member 30 is aligned with the opening of the mounting hole portion 81 . does not pass through That is, since the female threaded portion 21b provided in the body 10 and the female threaded portion 91b provided in the deformed portion 91 are screwed together with the male threaded portion 33b of the lid member 30, the opening end of the mounting hole portion 81 and the male threaded portion 33b are screwed together. It is possible to prevent foreign matter from entering and adhering to the meshing portion of the gear. In addition, according to the present embodiment, since the opening end of the mounting hole portion 81 does not exist at the threaded portion between the male screw portion 33b and the female screw portions 21b, 91b, foreign matter such as burrs that are likely to be formed at the opening end need to be taken into account. The lid member 30 can be screwed together without doing so.

In addition, weight reduction can be achieved by increasing the diameter of the mounting hole portion 81 with respect to the pinion gear 7a. On the other hand, since the deformed portion 91 is provided only in a part of the mounting hole portion 81, it is possible to contribute to weight reduction. In other words, according to this embodiment, it is possible to reduce the weight and prevent deterioration of rotational performance and durability.

Further, as shown in FIG. 5 , the distal end of the peripheral wall portion 33 of the lid member 30 is positioned at the female screw portion 91 b of the deformed portion 91 . In other words, the externally threaded portion 33b of the lid member 30 is not exposed inside the body 10. As shown in FIG. As a result, it is possible to further prevent foreign matter such as burrs from falling into the meshing portion of the gear.

Further, when the lid member 30 is attached to the body 10, the contact surface 21c formed on the inner peripheral surface 21a of the tubular portion 21 and the contact surface (contact portion) 33a of the lid member 30 come into contact. As a result, alignment of the lid member 30 with respect to the side opening 13 of the body 10 can be performed. That is, according to this configuration, the center of the right central hole 23 of the body 10 supporting the right side of the handle shaft 5 and the left central hole 31 of the cover member 30 supporting the left side of the handle shaft 5 are aligned and concentric. degree is obtained. Therefore, the handle shaft 5 is supported so as to extend in the lateral direction with respect to the reel body 1, and the rotation of the handle shaft 5 becomes smooth.

Further, according to the present embodiment, the entire circumference of the peripheral wall portion 33 extends through the contact surface 33a and the male thread portion 33b of the lid member 30 to the circular inner peripheral surface 21a (the side opening portion 13) of the tubular portion 21. Supported by As a result, the load applied to the lid member 30 can be evenly dispersed over the entire circumference of the side opening 13, thereby avoiding stress concentration.

The accommodation recess 33c is a recess formed between the contact surface 33a and the male threaded portion 33b, and the sealing member 35 is fitted thereon. Therefore, it is possible to prevent water from entering between the peripheral wall portion 33 and the body 10 .

Further, according to the embodiment, since the side opening 13 of the reel body 1 and the lid member 30 are fixed by screwing, screws or the like are not required, and the number of parts can be reduced.

Next, another embodiment of the present invention will be described. FIG. 8 is an enlarged cross-sectional view around a deformed portion 91A of a spinning reel for fishing according to another embodiment of the present invention. This embodiment is different from the above-described embodiment in that the deformed portion 91A is provided with an overhanging portion 91e.

An internal threaded portion 91b is formed on the lid member 30 side of the inner surface 91a of the deformed portion 91A of this embodiment, and an overhanging portion 91e is formed on the pinion gear 7a (see FIG. 4) side. The protruding portion 91e protrudes radially inward (toward the handle shaft 5) from the inner surface 91a of the deformed portion 91A. As a result, the inner surface 91f of the protruding portion 91e is positioned radially inward (toward the handle shaft 5) from the inner peripheral surface 21a of the cylindrical portion 21. As shown in FIG. When the cover member 30 is attached to the tubular portion 21, the tip of the peripheral wall portion 33 is positioned at the female threaded portion 91b of the deformed portion 91A (or the female threaded portion 21b of the tubular portion 21).

According to this embodiment, the male screw portion 33b of the lid member 30 is not exposed inside the body 10 as well. Furthermore, according to the embodiment, since the deformed portion 91 is provided with the protruding portion 91e, it is assumed that the male threaded portion 33b of the cover member 30, the female threaded portion 21b of the cylindrical portion 21, and the female threaded portion 91b of the deformed portion 91 Even if foreign matter is generated by the screwing, the foreign matter can be accommodated in the projecting portion 91e. As a result, it is possible to more reliably prevent foreign matter from entering the meshing portion of the gear.
