A rolling-type one-way rotation restricting mechanism A is provided on the outer periphery of the collar 16 on the rear side of the bearing 17, and the one-way rotation restriction is controlled by the operation rod 20 and the operation knob 21 which are projected to the rear side of the reel body 1. Is done.
The drive gear 3 ′ is engaged with the pinion 7 a of the rotary shaft cylinder 7, and the rotor 18 is supported so as to be rotated in conjunction with the rotation of the handle body 6.
A spool shaft 23 with a spool 22 attached to the tip is slidably inserted into the center hole 7b of the rotary shaft cylinder 7 so as to be slidable back and forth. A sliding body 24 is attached to 23 a with screws 25.

A traverse cam shaft 8 of a sliding mechanism is supported in the reel body 1 in parallel with the spool shaft 23, and a small gear 26 is fitted to the tip of the traverse cam shaft 8 to prevent rotation. 26 is meshed with the pinion 7a.
A sliding body 24 is fitted to the traverse cam shaft 8 and an engaging claw (not shown) provided on the sliding body 24 is engaged with the traverse cam groove 8a.

The holding member 4 that is inserted into the hollow portion 3a made of a non-circular through hole having a hexagonal cross section from one end portion 3b of the drive shaft 3 has a hexagonal cross section. In addition, a non-circular fitting portion 4a, an engaging portion 4b composed of a protrusion (a collar portion), a conical portion 4c, a (left) male screw portion 4d, and a (left) female screw portion 4e in a central hole made of a through hole. Is formed.
The holding member 4 ′ inserted and fitted into the hollow portion 3 a formed of a non-circular through hole from the other end portion 3 c of the drive shaft 3 has a non-circular fitting portion 4 a whose outer shape is formed in a hexagonal shape. An engaging portion 4b, a conical portion 4c, an intermediate portion 4f, a (right) male screw portion 4g, and a conical portion 4c side (right) female screw portion 4h are formed in the center hole. .
The non-circular fitting portions 4a and 4a of the holding members 4 and 4 'are fitted to the non-circular hollow portion 3a while being prevented from rotating in the circumferential direction.
One side of the connecting member 5 has a (left) male screw portion 5a formed on the outer periphery, and the other side has a (right) male screw portion 5b formed on the outer periphery.
Therefore, one side is formed with a left male screw, the other side is formed with a right male screw, and both are reverse screws.

A hexagonal hole 5c into which the hexagon wrench 27 is inserted and fitted is formed at the center of one end of the connecting member 5.
The non-circular fitting part 4a of the holding member 4, 4 'is formed in a taper shape with a somewhat larger diameter on the side of the engaging part 4b and attached to the drive shaft 3 so that the fitting part 4a is connected to the drive shaft 3 You may make it press-contact inside the hollow part 3a.
The handle body 6 is screwed into the (right) male screw portion 4g of the holding member 4 '(right) and the female screw portion 6b is screwed into the (left) male screw portion 4d of the holding member 4 (left). A screw portion 6a is formed.

When the holding members 4, 4 ′ are inserted and fitted into the hollow portion 3 a made up of the non-circular through hole of the drive shaft 3, as shown in FIG. The (left) male threaded portion 5a on one side of the connecting member 5 is somewhat screwed into the (left) female threaded portion 4e in the center hole, and the non-circular through hole is formed from one end 3b of the drive shaft 3. Is inserted into the hollow portion 3a.
The other holding member 4 ′ is inserted from the other end 3 c of the drive shaft 3 into the hollow portion 3 a formed of a non-circular through hole from the conical portion 4 c side.
Next, the hexagon wrench 27 is fitted into the hexagon hole 5c of the connecting member 5 through the center hole of the holding member 4, and the (right) male screw portion 5b on the other side of the connecting member 5 is connected to the (right) female screw of the holding member 4 '. When the hexagon wrench 27 is rotated so as to be screwed into the portion 4h, the (right) male screw portion 5b on the other side of the connecting member 5 is screwed into the (right) female screw portion 4h of the holding member 4 '. The holding member 4 ′ advances to the holding member 4 side, and the (left) male screw portion 5 a on one side of the connecting member 5 is screwed to the (left) female screw portion 4 e of the holding member 4. Go to the 4 'side.

As shown in FIG. 5, the rotation of the hexagon wrench 27 tightens the (right) male screw portion 5b and the (right) female screw portion 4h, and (left) the male screw portion 5a and (left) the female screw. When the screwing of the portion 4e is tightened, the engaging portions 4b, 4b of the metal holding members 4, 4 'are pressed against one end 3b and the other end 3c of the metal drive shaft 3, respectively. It is done.
The (left) male screw part 4d of the handle body 6 can be screwed into the (left) male screw part 4d at the end of the holding member 4, and the (right) male screw part 4g at the end of the holding member 4 ' The (right) female thread portion 6b of the handle body 6 can be screwed and attached, and the attachment of the handle body 6 is configured to be interchangeable left and right.

As described above, when the hexagon wrench 27 is rotated, the holding members 4 and 4 ′ which are screwed into the reverse screws of the connecting member 5 approach each other, and the engaging portions 4 b and 4 b are respectively one end portion 3 b of the drive shaft 3. And the other end portion 3c are in direct contact with each other and are pressed against each other, and play in the circumferential direction and the axial direction is less likely to occur between the drive shaft 3 and the holding members 4, 4 '.
When the non-circular fitting portion 4a of the holding members 4 and 4 'is formed in a slightly tapered shape with a somewhat large diameter toward the engaging portion 4b, the fitting portion 4a becomes the hollow portion 3a. It is also pressed inside.
When the holding members 4, 4 ′ inserted and fitted into the hollow portion 3 a made of a non-circular through hole of the drive shaft 3 and the connecting member 5 are prepared as a set, the handle body can be used to change the left and right of the conventional handle body. It becomes easy to change the handle of the reel, which is likely to cause backlash with the shafts inserted and removed, to the handle of the present invention which is less likely to generate backlash. By removing the holding members 4, 4 ′ and the connecting member 5, A conventional handle body for inserting and removing the shaft can be reattached, and both handle bodies can be used.
Therefore, if the holding members 4 and 4 'corresponding to the handle body are attached, various handle bodies can be attached. If a problem occurs in the attachment portion, the drive shaft 3 and the drive gear 3' need not be replaced. It can also be easily repaired by replacing the holding members 4, 4 '.
Further, an interposition member may be provided between the end portions 3b and 3c of the drive shaft 3 and the engaging portions 4b and 4b, and the members may be pressed through this, and the mounting position of the holding members 4 and 4 'can be adjusted.

When the fishing spinning reel is configured as described above, the holding members 4 and 4 ′ that detachably hold the handle body 6 are connected to each other through the hollow portion 3 a that is a non-circular through hole of the drive shaft 3. Since it is connected via the member 5 and is press-contacted to the drive shaft 3, the play is unlikely to occur.
The engaging portions 4b and 4b are in contact with the end portions 3b and 3c of the drive shaft 3, respectively, and are joined so that the holding members 4 and 4 'do not move to the opposite end portions. What is necessary is just to form the step part which hits the edge parts 3b and 3c even if it is not a protrusion and a collar part.
