  In the conventional drag mechanism, a spring member (coil spring) in which a wire having a circular cross section is formed in a spiral shape is used. In such a spring member, there is a possibility that the circumferential surfaces of adjacent wires contact each other during compression. When the circumferential surfaces of the wires are in contact with each other, the wires may be displaced in the radial direction of the spring member, and the spring member may be bent (buckled) in the radial direction. In the conventional drag mechanism, when the adjustment knob is tightened and the spring member is compressed, if the spring member is curved in the radial direction, there is a problem that the spring force applied from the spring member to the pressing member is biased.

  Therefore, an object of the present invention is to provide a fishing reel that solves the above-described problems and can stably apply the spring force of the spring member to another member.

  In order to solve the above problems, the present invention is a fishing reel comprising a spool around which a fishing line is wound and a drag mechanism for controlling the feeding of the fishing line when the fishing line is fed out from the spool. The drag mechanism is interposed between the adjustment knob, a pressing member that applies a braking force to the spool, and the adjustment knob and the pressing member. By adjusting the adjustment knob, the braking force is applied to the spool. A spring member that presses the pressing member, and the spring member is formed of a spirally formed wire, and the axial cross section of the wire is a rectangular cross section, and the axial cross section of the wire A cross-sectional secondary moment about an axis substantially perpendicular to the axial direction of the spring member passing through the centroid, and the drag mechanism includes a side wall surface facing the outer peripheral surface of the end of the spring member, Axial direction of the spring member A bottom surface in contact with the end surface of, is characterized in that is formed. The axial width of the spring member on the side wall surface may be larger than the axial width of the spring member at the end of the wire.

  In this configuration, the moment of inertia of the section about the axis parallel to the axis of the spring member passing through the centroid of the axis section of the wire is large. That is, since the spring member has a large bending rigidity in the radial direction, the spring member is difficult to bend in the radial direction.

In the fishing reel described above, the wire is a plate-shaped member, and the axial cross-sections of the adjacent wires are such that the sides adjacent to the axial direction of the spring member are parallel and perpendicular to the axial direction of the spring member. You may comprise so that it may become.
In this configuration, when the spring member is compressed, adjacent wires are brought into close contact with each other, so that the wires are not easily displaced in the radial direction of the spring member.

In the fishing reel described above, the wire may be formed in a wave shape that is uneven in the axial direction of the spring member, and the concave portions or the convex portions of the adjacent wire rods may be opposed to each other.
In this configuration, when the spring member is compressed, the convex portions of adjacent wire rods come into contact with each other and bend, so that the spring constant of the spring member is increased. Moreover, since it has elasticity in the state where the convex portions of the adjacent wire rods are in contact with each other, the interval between the adjacent wire rods can be reduced.

  In the fishing reel of the present invention, the spring member has a large bending rigidity in the radial direction, and the spring member is difficult to bend in the radial direction. Therefore, the spring force of the spring member can be stably applied to other members. Can do. And when the spring member of this invention is used for a drag mechanism, the braking force provided to a spool can be stabilized. Therefore, a desired braking force can be suitably applied to the spool.

  Moreover, in the axial cross section of an adjacent wire, when the side adjacent to the axial direction of a spring member is comprised so that it may become parallel and perpendicular | vertical to an axial direction, it will become difficult to shift | deviate wires to the radial direction of a spring member. The stability of the spring member can be further enhanced.

  In addition, when the wire is formed in a corrugated shape in the axial direction of the spring member, the spring constant of the spring member is increased and the interval between adjacent wires can be reduced. In addition, the workability when the spring member is incorporated into the fishing reel can be improved.

  Hereinafter, an embodiment of a fishing reel of the present invention will be described with reference to the drawings.

<First embodiment>
As shown in FIG. 1, the fishing reel 1 according to the first embodiment of the present invention can be rotated forward of the reel body 100 and a reel body 100 on which legs 101 are attached to a fishing rod (not shown). The spinning reel mainly includes a provided rotor 110, a spool 120 that moves back and forth in synchronization with the rotation of the rotor 110, and a drag mechanism 130 that controls the feeding of the fishing line from the spool 120.
In the following description, when referring to “front and back”, the direction shown in FIG. 1 is used as a reference.

A handle shaft 140 is rotatably supported on the reel body 100, and a handle 141 is attached to a protruding end portion of the handle shaft 140.
A drive gear 150 is attached to the handle shaft 140. The drive gear 150 meshes with a pinion gear 161 of a drive shaft cylinder 160 that extends in a direction orthogonal to the handle shaft 140.

  The drive shaft 160 is rotatably supported by the reel body 100, and a spool shaft 170 is inserted in the hollow portion so as to be movable in the axial direction. A rotor 110 is attached to the front end portion of the drive shaft cylinder 160.

  In the fishing reel 1, the handle 110 is rotated by operating the handle 141, and the drive shaft 160 is rotated via the drive gear 150 and the pinion gear 161, whereby the rotor 110 can be driven to wind. .

  An oscillating mechanism for moving the spool shaft 170 back and forth is provided at the rear end portion of the spool shaft 170. The oscillating mechanism includes an eccentric protrusion (not shown) provided in the interlocking gear 180 that meshes with the gear 151 of the drive gear 150, and a slider 181 attached to the rear end portion of the spool shaft 170. An eccentric protrusion is engaged with a guide groove (not shown) provided in the slider 181.

  The spool 120 includes a fishing line winding body portion 123 around which a fishing line (not shown) is wound between the skirt portion 121 and the front flange 122. An opening recess 124 that is a square hole such as a hexagon is formed on the front end surface of the spool 120. A drag mechanism 130 which will be described later is accommodated in the opening recess 124. The spool 120 is attached to the front end side of the spool shaft 170 via the drag mechanism 130.

  As shown in FIG. 2, the drag mechanism 130 has a desired braking force, that is, when the fishing line wound around the spool 120 is fed out to the spool 120 rotatably supported by the spool shaft 170. A desired braking force (drag force) is applied to 120. The drag mechanism 130 includes an adjustment knob 131, a pressing member 132, a spring member 133, and a braking member 134.

  The adjustment knob 131 and the pressing member 132 adjust the strength of the braking force that brakes the rotation of the spool 120 and also serves to prevent the spool 120 from coming off.

The pressing member 132 has a substantially hat-shaped cross section that opens to the front side. An insertion hole 132 b passes through the bottom 132 a of the pressing member 132. The spool shaft 170 is inserted into the insertion hole 132b, and the pressing member 132 is movable in the axial direction with respect to the spool shaft 170.
The pressing member 132 is disposed on the bottom surface (front surface) side in the opening recess 124 and is configured to press a braking member 134 described later with the bottom portion 132a.

The adjustment knob 131 has an operation portion (drag knob) 131 a protruding from the front surface and is locked to the front portion of the pressing member 132. A female screw part 131 b into which a male screw part 171 formed at the front end of the spool shaft 170 is screwed is provided at the center of the rear surface of the adjustment knob 131.
In addition, the rear surface of the adjustment knob 131 is formed in an opening recess shape that is a square hole such as a hexagon, and the outer periphery of the female screw portion 131b is axially movable and non-rotatably fitted to the adjustment knob 131. The part is formed in a hexagonal shape or the like corresponding to the rear surface of the adjustment knob 131.

  As shown in FIG. 3A, the spring member 133 is an elastic member in which a wire 133a that is a plate-like metal member is formed in a spiral shape. As illustrated in FIG. 3B, the axial cross section 133 b of the wire 133 a is a rectangular cross section that is wide in the radial direction of the spring member 133.

In the spring member 133 according to the first embodiment, as shown in FIG. 3C, the cross-sectional secondary moment with respect to the centroid G of the axial cross section 133 b of the wire 133 a is the axial direction X of the spring member 133 (FIG. 3). The cross-sectional secondary moment about the y-axis, which is the direction perpendicular to the axial direction X passing through the centroid G, is minimized so that the bending rigidity in the direction parallel to (b) is minimized (y The axis is the so-called weak axis. Then, in order to maximize the bending rigidity in the direction perpendicular to the axial direction X of the spring member 133, the cross-sectional secondary moment with respect to the x-axis, which is a direction parallel to the axial direction X passing through the centroid G, is maximized. (The x axis is the so-called strong axis).
That is, in the spring member 133 of the first embodiment, the bending rigidity in the radial direction is large, and the spring member 133 is difficult to bend (buckled) in the radial direction.
Note that the ratio of the cross-sectional secondary moment (Ixx) to the x-axis and the cross-sectional secondary moment (Iyy) to the y-axis is preferably set to Ixx: Iyy = 2 or more: 1, and particularly Ixx: Iyy = 8 or more: By setting it to 1, reliable drag performance can be obtained even when an impact in a direction perpendicular to the spool shaft (such as during the exchange with a fish pull) is applied.

As shown in FIG. 3A, both ends of the wire 133a are swung in a plane perpendicular to the axial direction of the spring member 133, and both ends of the spring member 133 are formed flat. Between both end portions of the wire 133a, the wire 133a adjacent in the axial direction is formed in a spiral at the same angle, and the surfaces of the spring member 133 facing in the axial direction are arranged in parallel.
In addition, the wire 133a adjacent to an axial direction is a site | part (section) arrange | positioned adjacent to the axial direction of the spring member 133 when the spring member 133 which consists of one wire 133a is side view.

  In the spring member 133, as shown in FIG. 3B, the axial cross section 133b of the wire 133a adjacent in the axial direction of the spring member 133 has an adjacent side 133c parallel and perpendicular to the axial direction of the spring member 133. It has become.

  As shown in FIG. 2, the braking member 134 is composed of a plurality of plate-like members arranged on the bottom surface (front surface) of the opening recess 124. When the braking member 134 is pressed by the pressing member 132, it is pressed against the bottom surface of the opening recess 124.

In the drag mechanism 130, when the operation portion 131a of the adjustment knob 131 is picked and rotated, the female screw portion 131b moves along the axial direction of the spool shaft 170, and the amount of rotation operation of the adjustment knob 131 (in the axial direction). The spring member 133 is compressed or expanded according to the amount of movement).
Then, the spring force of the spring member 133 acts on the pressing member 132, and the pressing member 132 presses the braking member 134, so that the braking member 134 is pressed against the bottom surface of the opening recess 124, and the spool 120 rotates in the fishing line feeding direction. Is applied with braking force.

  In the fishing reel 1 of the first embodiment as described above, as shown in FIG. 3C, the axial direction X (FIG. 3B) passing through the centroid G of the axial cross section 133b of the wire 133a of the spring member 133. ) See)), and the moment of inertia of the cross section with respect to the x axis, which is parallel to the reference), is large, and the spring member 133 has a large bending rigidity in the radial direction.

  3B, the wire 133a is a plate-like member, and the axial cross section 133b of the adjacent wire 133a is parallel to the side 133c adjacent to the axial direction of the spring member 133. It is comprised so that it may become perpendicular | vertical to an axial direction, and when the spring member 133 is compressed, since the adjacent wire 133a will closely_contact | adhere, it is hard to shift | deviate to the radial direction of the spring member 133.

  Accordingly, in the fishing reel 1 of the first embodiment, the spring member 133 is difficult to bend in the radial direction, and at the same time, the spring member 133 is easily positively bent in the axial direction. 2 can be stably applied to the pressing member 132 shown in FIG. 2, and the braking force applied to the spool 120 can be stabilized. Therefore, a desired braking force can be suitably applied to the spool 120.

As mentioned above, although 1st embodiment of this invention was described, this invention is not limited to said 1st embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, as shown in FIG. 4, a spring member 135 may be used in which a wire 135 a is uneven in the axial direction and is formed in a wave shape in which the unevenness is continuous in the turning direction. In the spring member 135, the concave portions or the convex portions 135b of the adjacent wire members 135a are opposed to each other, and the apexes of the convex portions 135b facing each other are in contact with each other.

  In this configuration, when the spring member 135 is compressed, the convex portions 135b of the adjacent wire members 135a are bent, so that the spring constant of the spring member 135 is increased. Moreover, since it has elasticity in the state which the convex part 135b of the adjacent wire rod contacted, the space | interval of the adjacent wire rod 135a can be made small. Therefore, the spring member 135 can be reduced in size and weight. In order to increase the spring constant, there is a method using a plurality of spring washers, but in that case, in the configuration of the first embodiment, in addition to the effects described above, the spring member 135 is connected to a fishing reel. It is possible to improve workability when it is incorporated into the hood.

In the fishing reel 1 of the first embodiment, as shown in FIG. 3C, the axial cross section 133 b of the wire 133 a of the spring member 133 is formed in a rectangular cross section that is wide in the radial direction Y. However, the axial cross section of the wire 133a only needs to be formed so that the secondary moment of section relative to the centroid is minimized in a direction substantially parallel to the axial direction of the spring member 133, and the shape thereof is limited. Is not to be done.
For example, as shown in FIG. 5A, the shaft section 136b of the wire 136a may be formed in a trapezoid that is wide in the radial direction of the spring member. 5A, two parallel sides of the trapezoid are arranged in the axial direction of the spring member, but two parallel sides of the trapezoid may be formed in the radial direction of the spring member. . Further, as shown in FIG. 5B, the shaft section 137b of the wire 137a may be formed in an oval shape that is wide in the radial direction of the spring member.
Moreover, as shown in FIG.5 (c), you may form the axial cross section 138b of the wire 138a in the parallel square wide in the radial direction of a spring member. Thus, when the axial section 138b is a parallel square, the axial direction in which the secondary moment of inertia passing through the centroid of the axial section 138b is minimized is about 5 degrees with respect to the direction perpendicular to the axial direction of the spring member. However, a sufficient effect can be obtained. In addition, if the difference with respect to the direction perpendicular | vertical to the axial direction of a spring member is the range of about +/- 15 degree, sufficient effect can be acquired and it defines as a substantially perpendicular | vertical range.
Furthermore, you may form the axial cross section of a wire in the ellipse shape wide in the radial direction of a spring member.

<Reference example>
As shown in FIG. 6, a fishing reel 2 according to a reference example of the present invention includes a reel body 200 mounted on a fishing rod (not shown), a spool 220 rotatably provided on the reel body 200, and a fishing line on the spool 220. This is a dual-axis reel mainly comprising a level wind mechanism 210 for uniformly winding the wire and a drag mechanism 230 for controlling the feeding of the fishing line from the spool 220.

A spool shaft 270 is rotatably supported between the left and right frames 200a and 200b of the reel body 200, and a spool 220 around which a fishing line is wound is attached to the spool shaft 270.
The spool 220 is configured to be rotated by rotating the handle 241, and the handle 241 is attached to the distal end portion of the handle shaft 240 protruding from the right side plate 201 b of the reel body 200.

A drive gear 250 is rotatably provided on the handle shaft 240. The drive gear 250 transmits the rotational movement of the handle 241 to the spool shaft 270.
The reel body 200 also houses a drag mechanism 230 that engages with the drive gear 250 and applies a predetermined braking force (drag force) to the spool 220.

  The drag mechanism 230 is interposed between the adjustment knob 231, a cylindrical pressing member 232 attached to the handle shaft 240 on the adjustment knob 231 side with respect to the drive gear 250, and the adjustment knob 231 and the pressing member 232. And a plate-like braking member 234 that is in contact with the pressing member 232 side of the drive gear 250.

In the drag mechanism 230 described above, the pressing member 232 is attached to the handle shaft 240 so as to be movable in the axial direction. When the adjustment knob 231 is turned, the spring member 233 is compressed or extended according to the turning operation amount (movement amount in the axial direction) of the adjustment knob 231.
Then, the spring force of the spring member 233 acts on the pressing member 232, and the pressing member 232 presses the braking member 234, so that the braking member 234 is pressed against the side surface of the drive gear 250 and the spool 220 rotates in the fishing line feeding direction. Is applied with braking force.

The spring member 233 used in the drag mechanism 230 of the reference example has the same configuration as the spring member 133 used in the drag mechanism 130 (see FIG. 2) of the first embodiment.
That is, the moment of inertia of the section about the axis in the direction parallel to the axis of the spring member passing through the centroid of the shaft section of the wire 233a of the spring member 233 is large, and the spring member 233 has a large bending rigidity in the radial direction. It has become.
Also, the wire 233a of the spring member 233 is a plate-like member, and the axial cross section of the adjacent wire 233a is such that the sides adjacent to the axial direction of the spring member 133 are parallel and perpendicular to the axial direction of the spring member 233. Thus, the wire members 233a are hardly displaced in the radial direction of the spring member 233.
As described above, in the fishing reel 2 of the reference example, the spring member 233 is difficult to bend in the radial direction similarly to the fishing reel 1 (see FIG. 1) of the first embodiment. Since the spring force can be stably applied to the pressing member 232, the braking force applied to the spool 220 can be stabilized. Therefore, a desired braking force can be suitably applied to the spool 220.

Note that, in the fishing reel 2 of the reference example, similarly to the first embodiment, the wire member of the spring member may be uneven in the axial direction, and the spring member formed in a wave shape by continuing this unevenness in the turning direction may be used. Good (see FIG. 4).
Further, the axial cross section of the wire rod of the spring member is formed so that the secondary moment of inertia about the axis in the direction substantially perpendicular to the axial direction of the spring member passing through the centroid is minimized, as in the first embodiment. The shape is not limited.
