The boss portion that supports the locking member is reinforced by screwing the mounting screw of the side cover member.

  1-3 illustrate a fishing reel 10 according to a preferred embodiment of the present invention.

  As shown in FIGS. 1 and 2, the fishing reel 10 of this embodiment is formed as a double-bearing type manually wound reel. The reel main body 12 of the fishing reel 10 has a side plate which is a side cover member by a plurality of screw members 18 on the outer sides of a pair of left and right frames 16a and 16b integrated by a columnar connecting member 14 and the like. 20a and 20b are attached and formed as a rigid housing as a whole, and are fixed to the fishing rod via the attachment legs 22.

  The spool 24 around which the fishing line is wound is rotatably supported between the left and right frames 16a and 16b, and the right side plate 20b supports a winding drive unit 46 that rotationally drives the spool 24. Various mechanisms such as a driving force transmission system and a drag system of the winding drive unit 46 are accommodated in the space defined by the right frame 16b. In this embodiment, especially the right frame 16b of the reel body 12 forms a drive component mounting portion for arranging the winding drive mechanism.

  Between the frames 16a and 16b of the reel body 12, both ends of a spool shaft 24a that is mounted with a spool 24 and rotates together with the spool 24 are rotatably supported, for example, via ball bearings 26a and 26b as shown. Has been. An end projecting from one end side of the spool shaft 24a through the right frame 16b is formed as a pinion shaft 28a that is coaxially arranged integrally with the spool shaft 24a, and is rotatable on the side plate 20b via a bearing 26c. Supported by On the pinion shaft 28a, the pinion 28 that is rotationally driven by the handle 30 is movably supported.

  The pinion 28 has a cylindrical structure that is inserted through the pinion shaft 28a, and is supported on the pinion shaft 28a so as to be rotatable and movable in the axial direction. As shown in FIG. 2, the pinion 28 is operated by turning on and off the clutch mechanism 34 through the clutch lever 32 having the support shaft 32a passing through the right side plate 20b and supported by the right side plate 20b. It is possible to move between an engagement position that fits with the spool shaft 24a and rotates integrally with the spool shaft 24a, and a non-engagement position in which the engagement state with the spool shaft 24a is released.

  The movement of the pinion 28 is performed by moving the operating member 36 engaged with the circumferential groove 28b formed in the pinion 28 along the pinion shaft 28a in conjunction with the ON / OFF operation of the clutch mechanism 34. Can do. When the pinion 28 is disposed at the engagement position shown in FIG. 1, the clutch-on fishing line can be wound, and at the non-engagement position (not shown), the clutch-off spool-free rotation state is established. When the handle 30 is rotated from this clutch-off state, it can be returned to the clutch-on state via a return mechanism (not shown).

  The actuating member 36 of this embodiment has a short shaft 38 (FIG. 1) in which the tip of each arm portion extending radially outward from the center portion that fits in the circumferential groove 28 b of the pinion 28 projects from the right frame 16. And is slidably mounted on the right frame 16b. The clutch mechanism 34 is provided on the operating plate 40 that reciprocates between the right frame 16b and the operating member 36 in the direction close to and away from the pinion 28 indicated by the arrow S along the right frame 16b. When the operating plate 40 moves to the pinion 28 side, the cam 40a moves in a direction to separate the arm portion of the operating member 36 from the right frame 16b. By the movement of the operating member 36, the pinion 28 is moved to the right side plate 20b side through the circumferential groove 28b, the engagement between the spool shaft 24a and the pinion 28 is released, and the clutch is turned off. The spool 24 can freely rotate.

  In order to move the operation plate 40, the link member 42 (FIG. 2) is connected to the support shaft 32 a of the clutch lever 32 so as not to rotate, and the engagement pin 42 a provided on the link member 42 is connected to the elongated hole of the operation plate 40. The clutch lever 32 and the operating plate 40 are connected by being fitted to 40b. The actuating plate 40 is urged and held by a known allocating spring (not shown) at each position in the clutch ON state and the clutch OFF state.

  Further, the pinion 28 meshes with a drive gear 44 that rotates by feeding the fishing line. The drive gear 44 is rotatably supported by a handle shaft 30a as a support shaft constituting the winding drive unit 46. Both ends of the handle shaft 30a are rotatably supported by bearings 48 (only one of them is shown) on the right frame 16b and the side plate 20b.

  When the handle shaft 30a is rotated in the fishing line winding direction by the handle 30 attached to the outer end portion thereof, the drive gear 44 is connected via the drag mechanism 50 inserted between the drive gear 44 and the handle shaft 30a. Is rotated, and the pinion 28 is rotated accordingly. When the clutch mechanism is in the clutch ON state, the spool shaft 24a is driven to rotate, and the spool 24 is rotated. At this time, the fishing line is evenly wound on the spool 24 by a level wind mechanism (not shown).

  In the middle of the handle shaft 30a, there is provided a roller type one-way clutch 52 that allows the handle shaft 30a to rotate only in one direction, which is the fishing line winding direction. Further, a ratchet 54 is fitted to the inner end of the handle shaft 30a as a rotating body that rotates in conjunction with the rotation of the handle 30, and is attached to the right side plate 20b of the reel body 12 as a locking member. Mesh with the stopper 56. Even when the one-way clutch 52 slips, the ratchet 54 and the stopper 56 are mechanically engaged with the teeth of the ratchet 54 so that the ratchet 54 and the handle, which are rotating bodies, are engaged. A reverse rotation prevention mechanism capable of reliably preventing the reverse rotation of the shaft 30a is formed. The reference numeral 54a projects from the ratchet 54 to the right frame 16b side and operates a return mechanism (not shown) for returning to the clutch ON state when the handle 30 is rotated from the clutch OFF state. Show the boss.

  As shown in FIG. 3 in an enlarged manner, the stopper 56 is formed with a claw for locking the teeth of the ratchet 56 at its distal end, and the right frame 16b through a through hole 56a formed at the proximal end. Is attached to the boss portion 60 protruding from the right side plate 20b. The stopper 56 is always urged in the direction in which the tip end engages with the ratchet 54 by the other end of the coil spring 58 having one end fixed to the right frame 16b.

  The boss portion 60 of the present embodiment is formed in a stepped structure having a large diameter portion 60a on the right frame 16b side and a small diameter portion 60b on the right side plate 20b side, and the large diameter portion 60a and the small diameter portion 60b A step portion 60c is formed therebetween. The stopper 56 is positioned with respect to the right frame 16b and the ratchet 54 by fitting the through hole 56a at the base end portion to the small diameter portion 60b and placing the stopper 56 on the stepped portion 60c. After the stopper 56 is mounted on the boss 60 and positioned, the coil spring 58 is mounted on the small diameter portion 60b, and the end of the coil spring 58 is locked to the right frame 16b and the stopper 56, respectively. It can swing around the boss 60.

  In this way, the boss portion 60 that supports the stopper 56 in a swingable manner has a screw hole 62 formed in the central portion along the axis of the small diameter portion 60b, and the screw member 18 for attaching the right side plate 20b to the right frame 16b. Can be screwed together.

  Thus, the boss portion 60 that supports the stopper 56 that is a locking member for preventing reverse rotation of the handle shaft 30a and the ratchet 54 also serves as a boss portion that screws the screw member 18 for mounting the right side plate 20b. As a result, the entire space of the reel body 12 can be effectively utilized by maximally utilizing the limited space in the reel body 12 in which drive parts such as the handle shaft 30a of the winding drive mechanism, the drive gear 44, and the drag mechanism 50 are mounted. By downsizing and further using the mounting screw member 18 as a stopper for the stopper 56, the number of parts and the cost can be reduced.

  Further, the boss portion 60 that supports the stopper 56 is screwed into the screw member 18 for attaching the right side plate 20b, whereby the boss portion 60 is reinforced by the screw member 18 and the right side plate 20b. Thereby, the small diameter part 60b of the boss | hub part 60 can be further reduced in diameter, and the space enclosed by the right frame 16b and the right side board 20b can also be utilized more effectively. As shown in FIGS. 1 and 3, it is possible to increase the strength by integrating the boss portion 60 with the peripheral wall portion 16c of the right frame 16b. However, the boss portion 60 is separated from the peripheral wall portion 16c. It is also possible to form.

A rotor 136 provided with a bail 132 and a fishing line guide 134 is integrally attached to the tip of the shaft tube 130 provided with the pinion 126, and the shaft tube 130 extends in a direction perpendicular to the handle shaft 122. An existing spool shaft 138 passes therethrough. The spool shaft 138 is disposed concentrically with the pinion 126, and can be moved back and forth along the direction orthogonal to the handle shaft 122, that is, the axial direction of the pinion 126 by the spool reciprocating device 140. A spool 116 around which a fishing line is wound is attached to the tip of the spool shaft 138.

  The fishing reel 110 according to the present embodiment has a ratchet 142 as a rotating member that is fixedly attached to the cylindrical shaft 130 as a reverse rotation prevention mechanism, and a locking member that engages with the ratchet 142 to prevent reverse rotation. As a stopper 144. Similar to the ratchet 54 of the above-described embodiment, the ratchet 142 has a number of claw portions that form a gently inclined surface on the fishing line winding side and a steeply inclined surface on the reverse rotation side. The engagement end 144a that engages with the claw portion is formed in a plate shape. When the cylindrical shaft 130 and the ratchet 142 are reversed in the fishing line feeding direction, the reverse rotation is prevented and the fishing line is rotated in the fishing line winding direction. In this case, the cylindrical shaft 130 and the ratchet 142 are configured to be rotatable.

  The stopper 144 is attached to a boss portion 148 formed integrally with the reel body 112a via the intermediate portion 144b, and the arm portion 144c is directed rearward, that is, in a direction opposite to the spool 116, from the intermediate portion 144b. It extends in a direction substantially orthogonal to each other, and has a shape bent in an L shape as a whole. Specifically, a through-hole 146 formed in the intermediate portion 144 b is attached to a column or small diameter portion 150 of a boss portion 148 parallel to the handle shaft 122, and the engagement end 144 a is engaged with the ratchet 142 by the spring member 152. It is energized in the direction of matching. A screw hole 154 for screwing the attachment screw member 114 of the lid body 112b is formed in the small diameter portion 150 provided in the boss portion 148.

  Further, the stopper 144 is rotated via the arm portion 144c of the stopper 148 so that the engaging end 144a moves between the position where the engaging end 144a is engaged with the ratchet 142 and the position where it is not engaged. A switching lever 156 is provided at the rear end, and an operating portion 158a provided at the tip of a rod member 158 connected to the switching lever 156 performs a switching operation through an intermediate lever 160 pivotally attached to the reel body 112a.
