[0003] The spinning reel for fishing described in Japanese Utility Model Publication No. 52-878 has a spool shaft which is rotatable back and forth in a back-and-forth direction and which is stopped from rotating, so that the spool is rotatably held forward so that it can be withdrawn. A stopper is provided at the rear of the spool on the spool shaft, and a locking member comprising a retaining ring is detachably attached to the tip of the spool shaft, and the spool is sandwiched between the locking member and the stopper. If the lock is removed from the spool shaft, the spool can be removed from the spool shaft.

The leading end of a cap-shaped knob placed on the tip of the spool shaft comes into contact with the locking member. If the knob is pushed in against the spring force of the locking member, the tip of the knob can be used. The latch is pushed apart and separated from the groove on the spool shaft. Thereby, the spool can be pulled out from the spool shaft.

In the spinning reel described in Japanese Utility Model Publication No. Sho 62-30947, a spool shaft is rotatably reciprocally slidable in a forward and backward direction, and a spool receiver is rotatably held so as to be able to be pulled out forward of the spool shaft. A spool is rotatably held in the receiver. A stopper for the spool receiver is provided on the spool shaft and at the rear of the spool receiver, and a locking member formed of a snap ring is detachably attached to the tip of the spool shaft, and the spool is sandwiched between the stopper and the locking member. Further, a pressing body is screwed into a male screw formed in a front portion of the spool receiver, a braking element is interposed between the pressing body and the spool, and the pressing body is turned by a drag knob. Thus, when the drag knob is rotated in any direction by a desired angle, the braking force on the spool of the braking element can be adjusted.

[0006] The tip of a tubular knob inserted into the cavity of the spool receiver comes into contact with the locking member.
If the knob is pushed into the spool receiver against the spring force of the locking tool, the locking tool is deformed by the tip of the knob and the spool receiver is released. Thereby, the spool can be pulled out from the spool shaft.

In the spinning reel for fishing disclosed in Japanese Patent Application Laid-Open No. 7-213201, a brake cylinder is rotatably mounted on a spool shaft which is reciprocally slidable in the front-rear direction and is stopped from rotating.

Further, a locking member made of a ring-shaped spring is detachably attached to the tip of the spool shaft, and the drag knob and the spool are sandwiched between the locking member and the brake cylinder from the front and rear. Thus, by rotating the drag knob, the pressing body can be turned to increase or decrease the braking force of the braking element on the brake cylinder.

Further, the tip of a cap-shaped knob placed on the tip of the spool shaft comes into contact with the locking tool. If the knob is pushed in against the spring force of the locking tool, the locking tool is pushed apart by the tip of the knob and separated from the spool shaft. Thereby, the spool can be pulled out from the spool shaft.

And a bail arm 7 attached to the rotor 6.

The handle 3, the spool shaft 4 and the rotor 6 are connected via a transmission mechanism provided in the reel body 2. In this transmission mechanism, a pin (not shown) is fixed to a side surface of the gear 8 which rotates with the rotation of the handle 3, and this pin is inserted into a vertical groove (not shown) of the slider 9. The armature 9 is fixed to the spool shaft 4, and the rotational motion of the handle 3 is converted into a reciprocating linear motion by a pin and a vertical groove and transmitted to the spool shaft 4. The spool shaft 4 performs a reciprocating linear motion whose rotation is stopped in the front-rear direction of the reel, and the spool 5 attached to the tip of the spool shaft 4 also performs a similar reciprocating linear motion.

The transmission mechanism has a pinion 10 that meshes with the gear 8, and the pinion 10 is coupled to the rotor 6 in a state that the pinion 10 rotatably covers the spool shaft 4. Therefore, when the handle 3 rotates, the rotor 6 swings around the spool 5 that moves back and forth together with the bail arm 7, and winds a fishing line (not shown) around the spool 5.

The spool 5 is held against the spool shaft 4 so as to be able to be pulled out forward of the spool shaft 4 so as to be prevented from rotating. That is, as shown in FIG. 2, a spool receiver 11 is fixed to a front portion of the spool shaft 4 by a pin 12, and the spool 5 is detachably mounted on the spool receiver 11. A non-circular flange 13 is formed at the rear end of the spool receiver 11. The flange 13 is provided in the groove 1 on the spool 5 side.

The number of the guide grooves 16 may be one, or three or more. Further, an elastic body 17 made of rubber, a spring, or the like is accommodated in the interior of the cavity of the locking member 15.

On the other hand, a projection 18 that fits into the guide groove 16 and moves relatively in the guide groove 16 with the rotation of the locking member 15 is fixed to the outer periphery of the spool shaft 4. The projection 18 is formed by both ends of a pin mounted so as to cross the spool shaft 4. The number of the projections 18 corresponds to the number of the guide grooves 16 and is provided according to the number of the guide grooves 16. After the spool 5 is put on the spool receiver 11, the locking tool 15 is put on the tip of the spool shaft 4, and the projection is inserted into the opening of the guide groove 16 and the spool 5 is twisted around the spool shaft 4. The locking tool 15 covers the spool shaft 4 as shown in FIG. 2 due to the relative movement between the projection 18 and the guide groove 16. When the projection 18 enters the inside of the guide groove 16, the elastic body 17 is pushed by the tip of the spool shaft 4 and elastically deforms.
The projection 18 is pushed into the notch 16 a of the guide groove 16. As a result, the locking member 15 is fixedly held at the leading end of the spool shaft 4, and sandwiches the spool 5 with the flange 13 at the trailing end.

As shown in FIG. 2, the locking member 15 is housed in a cavity of the spool 5 on the front side of the bobbin cylinder. The front end of this cavity is closed by an end plate 19
A projection 15a at the tip of the locking tool 15 protrudes outward from the central hole 19a. The projection 15a is connected to the rear through a step 15b. The step 15b faces the inner peripheral edge of the center hole 19a of the end plate 19, and the rear end of the locking member 15 faces the front end surface of the bobbin cylinder. As a result, the locking member 15 is retained in the cavity of the spool 5. , Is prevented from falling outside.

At the tip of the spool shaft 4, a locking member 15 for holding the spool 5 from the front and back together with the pin 20 is detachably attached. As shown in FIGS. 4 and 6, the locking member 15 is formed in a cap shape, and is rotatably covered on the tip of the spool shaft 4. Two guide grooves 16 extending in a direction intersecting the length direction of the spool shaft 4 and opening at the rear end of the locking member 15 are formed in the engagement cylinder 15c of the locking member 15 into which the tip of the spool shaft 4 enters. It is formed in a slit shape. The guide groove 16 extends back and forth so as to pivot around the engagement cylinder 15c, and a notch 16a is formed at each end. The number of the guide grooves 16 may be one, or three or more. An elastic body 17 made of rubber, spring, or the like is accommodated in the interior of the cavity of the locking member 15 so as to face the tip of the spool shaft 4.

On the other hand, a projection 18 which fits into the guide groove 16 and which relatively moves in the guide groove 16 with the rotation of the locking member 15 is fixed to the outer periphery of the spool shaft 4. The protrusion 18 is formed by both ends of a pin mounted on the spool shaft 4 so as to cross the axis thereof. The number of the projections 18 corresponds to the number of the guide grooves 16 and is provided according to the number of the guide grooves 16. After covering the spool 5 on the spool receiver 11, the stopper 15 is placed on the tip of the spool shaft 4,
When the projection 18 is inserted into the opening of the guide groove 16 and twisted around the spool shaft 4, the relative movement between the projection 18 and the guide groove 16 causes the locking member 15 to move the spool shaft 4 as shown in FIG. To cover. When the projection 18 enters the inside of the guide groove 16, the elastic body 17 is pushed by the tip of the spool shaft 4 and elastically deforms, and the projection 18 is pushed into the notch 16 a of the guide groove 16. As a result, the locking member 15 is fixedly held at the tip of the spool shaft 4, and pushes the drag knob 26 or the like onto the spool shaft 4 at the rear end.

The locking member 15 has the same configuration as in the first embodiment. That is, the locking member 15 is formed in a cap shape, and rotatably covers the tip of the spool shaft 4. Two guide grooves 1 extending in a direction intersecting the longitudinal direction of the spool shaft 4 and opening at the rear end of the locking member 15 are provided on the inner periphery of the cavity of the locking member 15 into which the tip of the spool shaft 4 enters.
6 (see FIG. 3). The guide groove 16 extends so as to pivot on the inner periphery of the locking member 25, and a notch 16a (see FIG. 3) is formed at each end. Guide groove 16
May be one or three or more. Further, an elastic body 17 made of rubber, a spring, or the like is accommodated in the interior of the cavity of the locking member 15.

On the other hand, a projection 18 which fits in the guide groove 16 and which relatively moves in the guide groove 16 with the rotation of the locking member 15 is fixed to the outer periphery of the spool shaft 4. The projection 18 is formed by both ends of a pin mounted so as to cross the spool shaft 4. The number of the projections 18 corresponds to the number of the guide grooves 16 and is provided according to the number of the guide grooves 16. After the spool 5 is put on the brake cylinder 33, the stopper 15 is put on the tip of the spool shaft 4, and a projection is inserted into the opening of the guide groove 16, and the spool 5 is twisted around the spool shaft 4. The locking tool 15 covers the spool shaft 4 as shown in FIG. 7 by the relative movement between the projection 18 and the guide groove 16. When the projection 18 enters the inside of the guide groove 16, the elastic body 17 is pressed by the tip of the spool shaft 4 and is elastically deformed.
Into the notch 16a of the guide groove 16. As a result, the locking member 15 is fixed and held at the tip of the spool shaft 4, and
The drag knob 26 is prevented from falling off the spool shaft 4.

The locking member 15 is housed in a cavity formed at the front of the drag knob 26. Before and after this cavity, an end plate for restraining the locking member 15 in the cavity is provided, the spool shaft 4 passes through the center hole of the rear end plate, and the center hole 31 of the front end plate is locked. Protrusion 15a at the tip of the tool 15
Penetrates. The protrusion 15a is connected to the rear through a step 15b, and the step 15b faces the inner peripheral edge of the hole 31 of the end plate, and prevents the locking member 15 from dropping out of the cavity.

The guide groove 16 and the projection 18 may be interchanged on the sliding contact surface between the locking member 15 and the end of the spool shaft 4. That is, the guide groove 16 may be provided on the spool shaft 4 and the projection 18 may be provided on the locking member 15.

Next, the operation of attaching and detaching the spool on the fishing spinning reel will be described.

In the state shown in FIG. 7, the spool 5 is
In order to remove the spool 3, the spool 5 is pushed slightly backward above the brake cylinder 33, and the projection 34 is released from a notch (not shown) of the groove 35. Therefore, the spool 5 is operated to twist around the central axis of the brake cylinder 33, and the protrusion 34 is relatively moved along the groove 35. Accordingly, the spool 5 can be removed from the tip of the brake cylinder 33.

In order to newly mount the spool 5 on the brake cylinder 33, the spool 5 is put on the brake cylinder 33, and then the opening of the groove 35 faces the projection 34 of the brake cylinder 33.
When the spool 5 is twisted around the axis of the spool shaft 4 so as to guide the spool 4 into the groove 35, the protrusion 34 relatively moves within the groove 35 and reaches the notch. The elastic body 38 is a rear end face 5a of the spool 5.
As a result, it is elastically deformed as a result of being pressed against the annular rib 37,
The protrusion 34 is pushed into the notch. As a result, the spool 5 is fixedly held by the brake cylinder 33.

As described above, the spool 5 is connected to the drag knob 26.
The drag knob 26 is connected to the spool shaft 4
Since it can be attached to and detached from the brake cylinder 33 independently of the above, the adjustment value of the braking force of the drag mechanism does not change when the spool 5 is attached or detached.

It should be noted that a projection, a step, or the like may be provided on the outer periphery of the drag knob 26, and the spool 5 may be restrained on the brake cylinder 33 by the projection, the step, or the like. This prevents separation between the projection 34 and the groove 35,
The spool can be prevented from falling off the brake cylinder 33. In this case, in order to remove the spool 5 from the brake cylinder 33, an operation of removing the drag knob 26 from the spool shaft 4 is required.

In order to remove the drag knob 26 from the spool shaft 4 in the state shown in FIG. 7, the locking member 15 is pushed slightly backward on the spool shaft 4 and the projection 18 is inserted into the guide groove 16.
Escape from the notch 16a. Therefore, the locking member 15 is operated to be twisted around the axis of the spool shaft 4, and the projection 18 is relatively moved along the guide groove 16. As a result, the lock 15 comes off the tip of the spool shaft 4 and the drag knob 2
6 can be extracted from the pressing body 25.

In this manner, the drag knob 26 is
When the pressing member 25 is removed from the spool shaft 4, the braking element 23 and the like can also be removed from the spool shaft 4.

To mount the drag knob 26 on the spool shaft 4, the drag knob 26 is inserted into the center of the spool 5 and put on the pressing body 25. Next, the opening of the guide groove 16 of the locking tool 15 faces the projection 18 at the tip of the spool shaft 4, and the locking tool 15 is rotated around the axis of the spool shaft 4 so as to guide the projection 18 into the guide groove 16. When twisted, the protrusion 18
6 to move to the notch 16a. Elastic body 17
Is elastically deformed as a result of being pushed by the tip of the spool shaft 4, and the projection 18 is pushed into the notch 16a. Thereby, the locking member 15 is fixed and held at the tip of the spool shaft 4. And
The drag knob 26 is sandwiched between the locking member 15 and the front end of the brake cylinder 33 from the front and rear, and is held on the spool shaft 4.

The braking force by the drag mechanism is adjusted by holding the knob 26a of the drag knob 26 and turning it in any desired direction. The cylinder 26b rotates at a fixed position on the spool shaft 4 together with the knob 26a, and the pressing body 25 moves forward or backward on the male screw 24 with this.

When the pressing body 25 moves backward, the spring force of the drag spring 30 increases, and the first, second, and third washers 27, 28, 29 are strongly pressed against the brake cylinder 33. As a result, the drag mechanism generates a large braking force. When the pressing body 25 moves forward, the spring force of the drag spring 30 decreases, and the braking force by the braking element 23 decreases.

In the embodiment shown in FIG. 7, the sleeve 5b at the rear of the spool 5 may be removed, and the removed sleeve 5b may be connected to the rear of the brake cylinder 33. Thus, the sleeve can be held by hand so that the brake cylinder 33 does not rotate on the spool shaft 4, and the attachment and detachment of the spool 5 can be easily performed.
