Description

The present invention relates to a spinning reel for fishing.

Generally, a spinning reel for fishing is provided with a drag mechanism that applies a braking force to a spool around which the fishing thread is wound in a fishing thread feeding direction.
Conventionally, in order to maintain the performance of the drag mechanism, a spinning reel for fishing that prevents water from entering the drag mechanism is known as one disclosed in Patent Document 1.

In the spinning reel for fishing of Patent Document 1, a seal member is arranged on a spool shaft that rotates relative to the spool in the skirt portion at the rear of the spool.

Japanese Patent No. 35252526

By the way, the area inside the skirt portion at the rear of the spool is an area where the spool that moves back and forth and the rotating rotor face each other, and structurally, a large gap with the outside is formed in the axial direction and the radial direction. Therefore, seawater, water, foreign matter, etc. easily enter the area inside the skirt during actual fishing.

In the spinning reel for fishing of Patent Document 1, a rubber waterproof sliding contact member is sandwiched between the regulating member mounted on the spool shaft and the spool, and the outer peripheral edge portion of the waterproof sliding contact member is sandwiched. It is in sliding contact with the rear inner peripheral surface of the spool on the rotor side. Therefore, in the spinning reel for fishing of Patent Document 1, the drag setting force set by the drag acts directly on the waterproof sliding contact member, and the holding force with respect to the spool changes depending on the strength of the drag setting force. That is, the waterproof performance of the spinning reel for fishing of Patent Document 1 is easily affected by the drag setting force.

In addition, since the waterproof sliding contact member is elastically deformed depending on the strength of the drag setting force, the axially restricted position of the spool may be slightly displaced in the axial direction, which may affect the thread winding state of the fishing thread wound around the spool. There is.

The present invention has been made to solve the above problems, and a spinning reel for fishing that is not affected by the drag setting force and has excellent waterproof performance while stabilizing the regulation in the axial direction of the spool. The purpose is to provide.

In order to achieve the above object, the spinning reel for fishing of the present invention is frictionally coupled with a spool shaft that reciprocates in the axial direction in conjunction with a rotation operation of a handle provided on the reel body and around the spool shaft. It is equipped with a drag mechanism that rotatably supports the spool. Further, a plate that is fixed to the spool shaft and comes into contact with the rear side of the spool that is pressed against the reel body side by the drag setting force of the drag mechanism to regulate the spool from moving to the reel body side. It is equipped with a reel-like regulation member. Further, it includes a first seal member attached to the outer peripheral side of the restricting member and a second seal member attached to the inner peripheral side of the rear surface of the restricting member. The first seal member is in elastically deformable sliding contact with the rear inner peripheral surface of the spool, and the second seal member is elastically deformable in sliding contact with the outer peripheral surface of the spool shaft. It is a feature.

In this spinning reel for fishing, the movement of the spool to the reel body side can be regulated by a regulating member fixed to the spool shaft. Therefore, the spool can be positioned at a predetermined position on the spool shaft. Further, since the first seal member is attached to the outer peripheral side of the restricting member and the second seal member is attached to the inner peripheral side of the rear surface of the restricting member, the spool and the restricting member are axially oriented. It is possible to eliminate a configuration in which a sealing member intervenes. Therefore, the seal member does not affect the fixing of the spool, and the spool can be positioned at a predetermined position on the spool shaft.
Further, the first sealing member is elastically deformably slidably contacted with the rear inner peripheral surface of the spool to seal the outer peripheral side of the regulating member, and the second sealing member is elastically deformably slidably contacted with the outer peripheral surface of the spool shaft. The inner peripheral side of the regulating member is sealed. Therefore, the space between the spool and the spool shaft is preferably sealed, and invasion of seawater, water, foreign matter, etc. into the spool is suppressed.

Further, the restricting member includes a locking portion that is locked to the spool shaft, a first attachment portion to which the first seal member is attached, and a second attachment portion to which the second seal member is attached. It is preferable to include a mounting portion.
With this configuration, the regulating member can be easily locked to the spool shaft, and the first seal member and the second seal member can be easily attached. Therefore, the configuration is simple and the assembling property is excellent.

Further, it is preferable that the first seal member is removable from the first mounting portion, and the second sealing member is removable from the second mounting portion.
With such a configuration, the assembling property is excellent. In addition, parts can be easily replaced, which is excellent in maintainability.

Further, it is preferable that the regulating member exhibits an annular body, and the rear inner peripheral surface is formed in an annular recess provided in the rear portion of the spool.
With such a configuration, the spool and the spool shaft can be suitably sealed with a simple configuration.

According to the present invention, it is possible to obtain a spinning reel for fishing that is not affected by the drag setting force and has excellent waterproof performance while stabilizing the regulation in the axial direction of the spool.

The retaining member 23 prevents the front bearing 22, the pressing member 21, the drag mechanism 20, and the rear bearing 24 from coming out from the inside of the winding body portion 3a.

Further, inside the winding body portion 3a, a seat plate 30 is arranged on the rear side of the support portion 3a1 via a washer 33. The seat plate 30 is a member that positions the rear side of the spool 3 with the spool shaft 8. Further, the seat plate 30 has a role of preventing seawater, water, foreign matter, etc. from entering the inside of the winding body portion 3a (drag mechanism 20) when seawater, water, foreign matter, etc., enter the inside of the rear flange portion 3c of the spool 3. Make up. Details of the seat plate 30 will be described later.

The front flange portion 3b includes a front flange main body 3b1 that extends radially along the front end of the winding body portion 3a, and a front cover 3f attached to the front outer peripheral portion of the front flange main body 3b1. The front flange body 3b1 functions as a wall portion to which the case member 51 described later of the sounding device 50 is attached. The front surface 3e of the front flange body 3b1 is formed so as to face forward. The front surface 3e functions as the bottom surface of the recess 55 and serves as a mounting surface for the sounding device 50.

The drag knob 40 includes a plate-shaped base portion 41, a knob portion 42, and a pressing portion 43. On the rear surface of the central portion of the base portion 41, a nut member 46 into which the small diameter portion 8c of the spool shaft 8 is screwed is arranged so as to be rotatable in the axial direction. A compression coil spring 45 is arranged between the nut member 46 and the pressing portion 43.

As shown in FIG. 3, the rear end portion of the pressing portion 43 extends inside the winding body portion 3a, and the rear end surface is in contact with the front end surface of the pressing member 21. A sealing member 43a for the pressing portion is provided on the outer peripheral portion of the rear end of the pressing portion 43 so as to be in liquid-tight contact with the inner peripheral surface 3h of the winding body portion 3a.

In such a drag knob 40, by screwing the knob portion 42, the pressing portion 43 on the rear side presses the pressing member 21 via the pressing force of the compression coil spring 45. As a result, the drag mechanism 20 is pressed by the pressing member 21, a braking force is generated in the drag mechanism 20, and the spool 3 is frictionally coupled to the spool shaft 8.

The sounding device 50 is a device that generates a click sound, and is a device that sounds when the spool 3 rotates with respect to the spool shaft 8 in the fishing thread feeding direction against the braking force of the drag mechanism 20. The sounding device 50 is arranged between the front side of the front flange body 3b1 of the spool 3 and the drag knob 40, and specifically, is provided in the recess 55 of the spool 3 (FIGS. 2 and 3). reference). That is, the sounding device 50 is installed by utilizing the wide space in front of the spool 3 on the side where the drag knob 40 is attached.

As shown in FIG. 3, the sounding device 50 includes a case member 51, a sounding gear 53, and a sounding pin 54 as a sounding member. The case member 51, the sounding gear 53, and the sound output pin 54 are integrally assembled to form a unit. The case member 51 is fixed to the spool 3 side.
