  A drive shaft cylinder having a pinion that meshes with the drive gear is rotatably supported between the bearings arranged at the front and rear of the reel body in order to maintain the meshing accuracy, and in a component arranged in front of the drive shaft cylinder. In order to smoothly move the spool shaft back and forth while being in sliding contact with the inner ring inner periphery of the bearing, high precision machined parts and ball bearings are used to maintain high precision concentricity between the drive shaft cylinder and the bearing. Thus, since the spool shaft is supported, the manufacturing cost becomes very expensive. Moreover, the number of parts increases, workability at the time of assembling becomes inferior, and fishing operability also decreases with weight.

  The present invention was created to solve such a problem, while maintaining the necessary functions of the rotating member and the sliding member that slides within the rotating member, simplifying assembly, It is an object to provide an inexpensive fishing spinning reel.

  In order to solve the above-described problems, a fishing spinning reel according to the present invention includes a reel body having a drive shaft cylinder and a spool shaft that penetrates the drive shaft cylinder, and the spool body includes the spool. A support portion that slidably supports the rear side of the shaft is formed, and the support portion is slid through the rear portion side of the spool shaft and slidably supports the outer peripheral surface of the rear side of the spool shaft in the axial direction. A projecting portion is provided on the front side of the inner peripheral surface of the drive shaft cylinder and includes a moving portion support hole. The projecting portion protrudes radially inward and supports the front side outer peripheral surface of the spool shaft so as to be slidable in the axial direction. It is characterized by.

According to the above-described invention, the rear side of the spool shaft is supported by the support portion formed integrally with the reel body. Further, the front side of the spool shaft is supported by a protruding portion formed on the radially inner side of the inner peripheral surface of the drive shaft cylinder. This eliminates the need for a ball bearing that supports the spool shaft, which has been required conventionally.
As a result, smooth back-and-forth movement of the spool shaft sliding in the rotating drive shaft cylinder and smooth rotation of the drive shaft cylinder are ensured, and operability is improved.

  Moreover, it is preferable that the support part of the fishing spinning reel is formed with a rotating part support part that supports the rear end part of the drive shaft cylinder so as to be rotatable in the circumferential direction.

  According to the rotating portion support portion of the support portion described above, the rear end portion of the drive shaft cylinder is supported so as to be rotatable in the circumferential direction, so that the assembly of the drive shaft cylinder can be simplified at low cost while maintaining the function of the drive shaft cylinder.

  As described above, according to the above-described invention, it is possible to provide an inexpensive fishing spinning reel that can improve operability and simplify assembly.

It is the schematic of the spinning reel for fishing of this embodiment. It is the enlarged view which extracted and expanded a part of spinning reel for fishing. It is the enlarged view which extracted and expanded a part of spinning reel for fishing of the modification.

  The fishing spinning reel according to the present embodiment will be described with reference to the drawings as appropriate. In the description of the embodiment, when referring to “front and back” and “up and down”, the direction shown in FIG. 1 is used as a reference.

  As shown in FIG. 1, a fishing spinning reel 1 includes a reel body 2 having a spool shaft 8 projecting forward, a rotor 3 rotatable around a central axis O of the spool shaft 8, and a front end of the spool shaft 8. And a spool 4 that moves forward and backward. Hereinafter, the center axis O of the spool shaft 8 is simply referred to as “center axis O”.

The reel body 2 is mainly formed with a leg portion 2a that extends upward and is attached to a fishing rod, and a cylindrical tube portion 2b that opens forward and through which the spool shaft 8 passes.
The reel body 2 rotatably supports a handle shaft 5 extending in the left-right direction, and a handle 6 is attached to an end portion of the handle shaft 5.
The reel body 2 further includes a drive gear 7 that engages with the handle shaft 5 and rotates about the left and right axis, and a cylindrical drive shaft cylinder 10 that meshes with the drive gear 7 and rotates.

As shown in FIG. 2, the drive shaft cylinder 10 is inserted into the cylinder portion 2b of the reel body 2, and the front end and the rear end of the drive shaft cylinder 10 protrude in the front-rear direction from the cylinder portion 2b.
A pinion 11 that meshes with the drive gear 7 is formed on the outer peripheral surface of the rear side of the drive shaft cylinder 10 that protrudes rearward from the cylinder portion 2 b, and the rotational motion of the drive gear 7 is transmitted to the drive shaft cylinder 10. It is like that.

  On the other hand, a male screw 12 is formed on the outer peripheral surface of the front end of the drive shaft cylinder 10 and a nut N is screwed together. And it is an outer peripheral surface of the drive shaft cylinder 10 and between the pinion 11 and the nut N, from the rear to the front, the annular cushioning material 30, the first bearing 31, the reverse rotation prevention mechanism 32, the second bearing 33, the fixed portion 3a of the rotor 3 is fitted around the outer periphery.

The cushioning material 30 is a member that prevents contact between the inner ring of the first bearing 31 and the pinion 11.
The first bearing 31 and the second bearing 33 are fixed to the reel body 2 by the outer ring being fitted in the cylinder portion 2 b of the reel body 2 so as not to rotate.
Further, the inner ring of the first bearing 31 is fitted on the outer periphery of the front side of the pinion 11 of the drive shaft cylinder 10 to support the drive shaft cylinder 10 rotatably. On the other hand, the inner ring of the second bearing 33 is externally fitted to an inner ring 35 described later of the reverse rotation prevention mechanism 32 and supports the drive shaft cylinder 10 via the inner ring 35 so as to be rotatable.

The reverse rotation prevention mechanism 32 is a mechanism for preventing the reverse rotation of the rotor 3.
The reverse rotation prevention mechanism 32 includes an inner ring 35 that is externally fitted to the drive shaft cylinder 10 and rotatably supported by the second bearing 33, an annular holding body 36 that holds a plurality of rolling members 36a, and a holding body. An outer ring 37 that is disposed outside 36 and is fitted in the cylinder portion 2b to prevent rotation, and a rotating member 38 that rotates together with the holding body 36 to perform switching braking.
Further, as shown in FIG. 1, an end portion 40 a of the switching operation shaft 40 that rotates in accordance with the operation of the operation knob 39 is engaged with the slit 38 a provided in the rotation member 38. When the operation knob 39 is set to the reverse rotation allowable position, the reverse rotation of the rotor 3 is allowed, and when the operation knob 39 is set to the reverse rotation prevention position, the reverse rotation of the rotor 3 is prevented. .

As shown in FIG. 2, the fixing portion 3 a of the rotor 3 is fastened to the pinion side by a nut N so that it does not fall off from the drive shaft cylinder 10.
In addition, the inner ring 35 of the reverse rotation prevention mechanism 32, the inner ring of the first bearing 31, and the cushioning material 30 are also fastened to the pinion side by the nut N. For this reason, the drive shaft cylinder 10 is prevented from falling off from the first bearing 31 and the reverse rotation prevention mechanism 32, in other words, from the cylindrical portion 2 b of the reel body 2.

A cylindrical sliding portion 13 extending rearward from the pinion 11 is formed at the rear end portion of the drive shaft cylinder 10. The sliding portion 13 is inserted into a circular hole 21 (rotating portion support portion) formed in the support portion 20 extending upward from the bottom surface in the reel body 2.
The support portion 20 is a portion for supporting the rear end portion of the drive shaft cylinder 10 and the rear portion side of the spool shaft 8, and a circular hole 21 formed in the front surface and a circle penetrating the bottom surface 21 a of the circular hole 21. A hole 22 (sliding portion support hole) is formed.

The circular hole 21 and the circular hole 22 are formed concentrically with the spool shaft 8 and the drive shaft cylinder 10.
Further, the inner peripheral surface 21 b of the circular hole 21 faces the outer peripheral surface 13 a of the sliding portion 13, and there is a sliding portion between the inner peripheral surface 21 b of the circular hole 21 and the outer peripheral surface 13 a of the sliding portion 13. A slight gap (not shown) for supporting 13 in a circumferentially rotatable manner is formed. Therefore, the rear end portion of the drive shaft cylinder 10 is supported by the support portion 20 in a state where the outer peripheral surface 13a of the sliding portion 13 is slidable on the inner peripheral surface 21b of the circular hole 21. In addition, although not shown in figure, the color (made of resin or other than resin) with favorable sliding property may be interposed between the circular hole 21 and the outer peripheral surface 13a.
Further, the bottom surface 21a of the circular hole 21 and the rear end surface 13b of the sliding portion 13 are separated from each other, so that the sliding resistance between the support portion 20 and the drive shaft cylinder 10 is reduced.

  Further, the inner peripheral surface 22 a of the circular hole 22 faces the rear outer peripheral surface of the spool shaft 8, and the spool shaft 8 is axially disposed between the inner peripheral surface 22 a of the circular hole 22 and the outer peripheral surface of the spool shaft 8. A slight gap (not shown) is formed so as to be slidably supported in the (front-rear direction). Therefore, the rear side of the spool shaft 8 is supported by the support portion 20 in a state where the outer peripheral surface of the spool shaft 8 is slidable on the inner peripheral surface 22 a of the circular hole 22.

In the support portion 20 of the present embodiment, the inner peripheral surface 21 b of the circular hole 21 is in contact with the outer peripheral surface 13 a of the sliding portion 13 as described above.
Here, when the sliding surface of the support portion 20 is designed to contact the inner peripheral surface of the drive shaft cylinder 10, the thickness of the support portion 20 is limited because the spool shaft 8 is in the drive shaft tube 10.
On the other hand, according to the configuration of the present embodiment, since the thickness of the support portion 20 is not limited, the portion that supports the rear end of the drive shaft cylinder 10 can be thickened to improve the strength.

In addition, an annular projecting portion 14 that projects radially inward from the inner peripheral surface is formed on the front side of the drive shaft cylinder 10. The protruding portion 14 is a portion for supporting the front side of the spool shaft 8, and the inner peripheral surface 14 a of the protruding portion 14 faces the front outer peripheral surface of the spool shaft 8.
Further, a slight gap (not shown) for supporting the spool shaft 8 so as to be slidable in the axial direction (front-rear direction) is provided between the inner peripheral surface 14a of the protrusion 14 and the front outer peripheral surface of the spool shaft 8. ) Is formed. Therefore, the front side of the spool shaft 8 is supported by the drive shaft cylinder 10 with the outer peripheral surface of the spool shaft 8 being slidable on the inner peripheral surface 14 a of the protruding portion 14.

  As shown in FIG. 1, the front end of the spool shaft 8 projects forward from the drive shaft cylinder 10, and the spool 4 is attached thereto. On the other hand, the rear end of the spool shaft 8 passes through the circular hole 22 of the support portion 20, and the slider 9 b of the oscillating mechanism 9 is attached.

  The oscillating mechanism 9 includes a worm shaft (traverse cam shaft) 9a that meshes with the pinion 11 of the drive shaft cylinder 10 and rotates, and a slider 9b that meshes with a groove of the worm shaft 9a and moves back and forth. When the handle shaft 5 is rotated by rotating the handle 6, the spool shaft 8 moves back and forth along the axial direction.

According to the fishing spinning reel 1, when the handle shaft 5 is rotated by rotating the handle 6, the rotor 3 is rotationally driven via the drive gear 7 and the drive shaft cylinder 10.
Here, the drive shaft cylinder 10 rotatably supported by the first bearing 31 and the second bearing 33 rotates smoothly. Moreover, although the rear part of the drive shaft cylinder 10 in which the pinion 11 is formed receives a load from the meshed drive gear 7, the sliding part 13 is supported by the support part 20. For this reason, the drive shaft cylinder 10 and the rotor 3 rotate smoothly, and the fishing line is smoothly wound.

  The spool shaft 8 that moves back and forth by the oscillating mechanism 9 is supported at the front side by the protruding portion 14 of the drive shaft cylinder 10 and at the rear side by the support portion 20. For this reason, even when a load is applied to the spool 4 when fishing a fish via a fishing line, the spool shaft 8 is not easily rattled and is slidably supported. As a result, the spool shaft 8 moves back and forth smoothly, and the fishing line is evenly wound around the spool 4 via the fishing line guide portion 3b (see FIG. 1).

As described above, according to the embodiment, the outer periphery on the rear side of the spool shaft 8 is directly supported by the support portion 20 formed on the reel body 2, and the front portion side of the spool shaft 8 is on the front side of the inner periphery of the drive shaft cylinder 10. It is directly supported by the formed protrusion 14. This eliminates the need for a ball bearing for supporting the spool shaft 8, which has been necessary in the past, and does not require a high-precision support structure (ball bearings, processed parts, etc.), and allows the front and rear of the spool shaft 8 to be smoothly and smoothly. As a result, the assembly can be simplified, and the fishing spinning reel 1 can be made inexpensive.
Further, since the rear side of the spool shaft 8 and the rear end of the drive shaft cylinder 10 are directly supported by the reel body 2 (supporting portion 20), the concentricity is high. For this reason, there is a very low possibility that the outer peripheral surface of the spool shaft 8 and the inner peripheral surface of the drive shaft cylinder 10 will be in contact with portions other than the protrusions 14. Smooth rotation is ensured and operability is improved.

As mentioned above, although the spinning reel 1 for fishing which concerns on embodiment was demonstrated, this invention is not limited to the example demonstrated by embodiment.
The support portion 20 of the embodiment includes the circular hole 21 and the circular hole 22, but as illustrated in FIG. 3, the support portion 20 </ b> A includes a cylindrical portion 23 (rotating portion support portion) instead of the circular hole 21. It may be.
The cylindrical portion 23 is formed concentrically with the spool shaft 8 and the drive shaft cylinder 10, and slides between an outer peripheral surface (sliding surface) 23 a of the cylindrical portion 23 and an outer peripheral surface 13 c of the sliding portion 13. A gap (not shown) is formed to support the portion 13 so as to be rotatable in the circumferential direction.
According to this, the rear end of the drive shaft cylinder 10 can be supported in a state in which the inner peripheral surface 13 c of the sliding portion 13 can slide on the outer peripheral surface (sliding surface) 23 a of the cylindrical portion 23.
However, according to the above-described modification, the spool shaft 8 is provided in the drive shaft cylinder 10 and the thickness of the cylindrical portion 23 is limited. However, since the outer periphery of the rear end of the sliding portion 13 is not covered, the sliding portion 13 A space around the outer periphery of the rear end can be secured.
In the case of supporting the outer peripheral side of the drive shaft cylinder 10 as in the support portion 20 of the embodiment, there is no such limitation, and the portion that supports the rear end of the drive shaft cylinder 10 is thickened to improve the strength. As described above, this can be achieved.
