  However, according to the prior art, when the reverse rotation preventing device and the switching lever are viewed in cross section, only the engaging portion (the portion where the protruding portion and the cam engage) has a shape protruding outward in the radial direction. For this reason, a substantially C-shaped dead space is formed on the outer peripheral side of the reverse rotation prevention device, and the fishing reel is enlarged.

  The present invention was created to solve such problems, and provides a fishing reel that is reduced in size by suppressing the formation of a dead space on the outer peripheral side of the reverse rotation prevention device. Is an issue.

  In order to solve the above problems, a fishing reel according to the present invention includes a reel body, a drive shaft that is rotated by a handle operation, an anti-reverse device interposed between the reel body and the drive shaft, A cylindrical reel member rotatably supported on the reel body and disposed on an outer peripheral side of the reverse rotation prevention device, wherein the switching control member of the reverse rotation prevention device and the reel A cylindrical member is engaged, and the drive shaft is switched to a reverse rotation prevention state or a reverse rotation permission state by a rotation operation of the cylindrical member.

According to the invention, since the tubular member and the switching control member are engaged, the reverse rotation prevention state and the reverse rotation permission state can be switched by the rotation of the tubular member. In other words, the switching lever that has been used in the past becomes unnecessary, and no dead space is generated on the outer peripheral side of the reverse rotation prevention device. Therefore, the fishing reel can be downsized.
Moreover, according to the said invention, when a cylindrical member is formed long in an axial direction and covers the outer peripheral side of a reverse rotation prevention apparatus, seawater, sand, etc. do not easily penetrate into the reverse rotation prevention apparatus. For this reason, saltiness etc. by the reverse rotation prevention device are suppressed, and the performance of the reverse rotation prevention device can be maintained over a long period of time.
According to the conventional anti-reverse device, only the engaging portion of the anti-reverse device and the switching lever protrudes outward in the radial direction, and the load is easily applied only to the engaging portion due to a collision or the like.
However, according to the invention, the cylindrical member surrounds the outer periphery of the reverse rotation prevention device, and it is not a shape in which only the engaging portion protrudes as in the conventional case. For this reason, it is possible to reduce the possibility that the load acts only on the engaging portion and breaks.

  Moreover, in the said invention, it is preferable that at least one part of the said cylindrical member is exposed outside so that it can operate.

  According to the said structure, since it is not necessary to form the knob for operation etc., the shape of a cylindrical member becomes simple and it can aim at reduction of a manufacturing man-hour.

  Or in the said invention, it is preferable that the said cylindrical member is provided with the operation part extended from an edge part and exposed outside.

  According to the said structure, even if it does not change the shape of the skirt part of the rotor which covers the outer peripheral side of a cylindrical member, a cylindrical member can be exposed outside. That is, it is excellent in versatility because it does not require a design change of other parts.

Moreover, in the said invention, it is preferable that the seal | sticker is provided in the inner peripheral side of the said cylindrical member.
In the present invention, the anti-reverse device is disposed in a cylindrical body front portion of the reel body, and a magnetic seal mechanism is provided at a front opening of the body front portion. It is preferable that the gap with the drive shaft is sealed.

  According to the said structure, possibility that seawater, dust, etc. penetrate | invade in a reverse rotation prevention apparatus can further be reduced.

In addition, on the outer peripheral side of the small-diameter portion 11, two bolt fixing portions 16 each having a female thread portion formed on the front end surface are formed.

(Reverse prevention device)
The reverse rotation prevention device 20 is a known device that prevents rotation in the other direction (hereinafter referred to as “reverse rotation”) while allowing rotation in one direction of the drive shaft cylinder 6.
As shown in FIG. 3, the reverse rotation preventing device 20 includes an inner ring 21 that is fitted to the outer peripheral side of the drive shaft cylinder 6 and fixed to prevent rotation, and an outer ring 22 that is inserted into the small diameter portion 11 and fixed to prevent rotation. A plurality of rollers 23 disposed between the inner ring 21 and the outer ring 22 and a retainer (switching control member) 24 are provided.

  As shown in FIG. 4, the retainer 24 has an annular shape and an annular portion 25 disposed behind the plurality of rollers 23, a plurality of extending portions 26 extending between the rollers 23 from the annular portion 25, and an annular shape And a projecting portion 27 projecting radially outward from the outer peripheral surface of the portion 25.

When the protrusion 27 is displaced (moved) in the circumferential direction, each roller 23 pressed by each extending portion 26 is displaced in the circumferential direction.
As a result, the roller 23 exerts a wedge action between the inner ring 21 and the outer ring 22 and the reverse rotation of the inner ring 21 (drive shaft cylinder 6) is prevented, or the roller 23 wedges between the inner ring 21 and the outer ring 22. The reverse rotation of the inner ring 21 (drive shaft cylinder 6) is permitted without exhibiting the action.

The protruding portion 27 passes through the third notch 15 c of the small diameter portion 11 and extends outward in the radial direction from the small diameter portion 11. In addition, the width | variety (length of the circumferential direction) of the 3rd notch 15c is formed wide, and the protrusion part 27 can be displaced to the circumferential direction.
Furthermore, an elliptical circular hole 28 penetrating in the front-rear direction is formed in the protrusion 27 (see FIG. 2).

(Operation ring)
As shown in FIG. 3, the operation ring 30 is a cylindrical member that surrounds the outer peripheral side of the body front portion 4 (the large diameter portion 10 and the small diameter portion 11). For this reason, the body front part 4 is covered with the operation ring 30, and seawater or the like hardly adheres to the reverse rotation preventing device 20 in the small diameter part 11. A skirt portion 104 of the rotor 101 is disposed on the outer peripheral side of the operation ring 30.

The operation ring 30 is assembled such that its inner peripheral surface partially abuts on the outer peripheral surface of the body front portion 4 and is slidable in the circumferential direction with respect to the body front portion 4.
As shown in FIG. 4, a portion of the inner peripheral surface of the operation ring 30 facing the third notch 15 c of the small diameter portion 11 has a recess 31 for accommodating the protruding portion 27 of the retainer 24 and a columnar shape. An engaging portion 32 that is inserted into the circular hole 28 of the protruding portion 27 and engages with the protruding portion 27 in the circumferential direction is formed.
For this reason, the operation ring 30 and the retainer 24 rotate in the same direction. That is, by rotating the operation ring 30, it is possible to switch between the reverse rotation prevention state and the reverse rotation permission state of the reverse rotation prevention device 20.

  As shown in FIG. 3, an operation knob 33 extending rearward and exposed from the skirt portion 104 of the rotor 101 is formed below the rear end portion of the operation ring 30. For this reason, the angler can rotate the operation ring 30 by holding the operation knob 33 and moving it in the circumferential direction (see arrow A in FIG. 1).

(Return contact section)
As shown in FIG. 3, the return contact portion 40 of the bale reversing mechanism is provided below the rear end portion of the operation ring 30.
The return contact portion 40 of the bale reversing mechanism is provided on the inner peripheral side of the arm 103 (see FIG. 1) when the rotor 101 rotates in the winding direction with the bail 102 (see FIG. 1) in the fishing line discharge position. This is a member for making contact with a return contact member (not shown) and for reversing the bail 102 (returning to the fishing line winding position). 1 is in a fishing line winding position.

  As shown in FIG. 5, the return contact portion 40 has a main body portion 41 that has an arc shape and contacts a return contact member (not shown), and extends radially inward from the inner peripheral surface of the main body portion 41. And a first leg portion 42 and a second leg portion 43 which are inserted into the mounting holes 17 and 18 of the body front portion 4 (large diameter portion 10).

The operation ring 30 is formed with a first leg through hole 34 for allowing the first leg portion 42 to pass therethrough and a notch 35 for allowing the second leg portion 43 to pass therethrough.
Further, each of the first leg through hole 34 and the notch 35 is formed wide in the circumferential direction, and the first leg 42 and the second leg 43 do not interfere with each other when the operation ring 30 is rotated. It is like that.
Further, as shown in FIG. 3, since the first leg portion 42 of the return contact portion 40 passes through the first leg through hole 34, the operation ring 30 is in the front-rear direction with respect to the first leg portion 42. The operating ring 30 does not fall off from the body front portion 4.

In addition, an upper through hole 36 penetrating in the radial direction is formed above the rear end portion of the operation ring 30. In the upper through hole 36, a retaining member 45 that is screwed into the female thread portion 19 of the body front portion 4 is disposed.
Here, the retaining member 45 is in contact (sliding) with the inner surface of the upper through hole 36. For this reason, it is difficult for the operation ring 30 to rattle in the front-rear direction.

(Rotating position holder)
As shown in FIG. 3, the rotational position holder 50 enters two concave portions 38 (only one concave portion 38 is shown in FIG. 3) formed in the inner peripheral surface of the operation ring 30 and arranged in the circumferential direction, and the operation ring 30. The position in the circumferential direction is held in the reverse rotation prevention state or the reverse rotation permission state.
The rotation position holder 50 of the present embodiment includes a cylindrical casing 51 that fits into a hole 11 a formed on the outer peripheral side of the small diameter portion 11, and a compression coil spring 52 that is accommodated in the casing 51. The pin 53 is always urged forward by the compression coil spring 53.
When the operation ring 30 is rotated to be in the reverse rotation prevention state or the reverse rotation permission state, the pin 53 enters one of the two recesses 38 of the operation ring 30 and the operation ring 30 is restricted from rotating.

As shown in FIG. 3, the magnetic seal mechanism 60 is integrally formed with a cylindrical permanent magnet 63 and a pair of magnetic plates 64 and 64 disposed on both end surfaces of the permanent magnet 63 with respect to the ring shape. It is a ring-shaped part.
The magnetic seal mechanism 60 is disposed in contact with the front end surface of the small diameter portion 11 and closes the front opening 11b of the small diameter portion 11.
As shown in FIG. 2, the magnetic seal mechanism 60 (magnetic plate 64) is formed with a pair of flange portions 61 projecting radially outward. And the magnetic seal mechanism 60 is being fixed to the small diameter part 11 by the flange part 61 being fastened by the volt | bolt (not shown) screwed together with the bolt fixing | fixed part 16 of the small diameter part 11. FIG.

As shown in FIG. 4, a gap S is formed between the magnetic seal mechanism 60 and the drive shaft cylinder 6, and the gap S is filled with a magnetic fluid (not shown).
The magnetic seal mechanism 60 forms a magnetic circuit in the gap S by the permanent magnet 63 in order to hold the magnetic fluid. For this reason, the outflow of the magnetic fluid is suppressed, and the sealing performance between the magnetic seal mechanism 60 and the drive shaft cylinder 6 (gap S) is extremely high.

The front seal 70 and the rear seal 71 are annular seal members.
The front seal 70 is fitted in a circumferential groove 62 formed in the magnetic seal mechanism 60 and seals between the magnetic seal mechanism 60 and the operation ring 30.
The rear seal 71 is fitted into the circumferential groove 12 of the large diameter portion 10 and seals between the large diameter portion 10 and the operation ring 30.
The front seal 70 and the rear seal 71 make it difficult for seawater or the like to enter between the operation ring 30 and the small diameter portion 11. Therefore, seawater or the like is prevented from adhering to the reverse rotation preventing device 20 in the small diameter portion 11 through the first notch 15a to the third notch 15c.

As described above, according to the embodiment, the operation ring 30 surrounding the outer periphery of the reverse rotation prevention device 20 constitutes an operation member that switches between the reverse rotation prevention state and the reverse rotation permission state, and the conventionally used switching lever becomes unnecessary. .
For this reason, the substantially C-shaped dead space conventionally formed in the outer peripheral side of the reverse rotation prevention apparatus 20 is not formed in the fishing spinning reel 100 of this embodiment.
Therefore, the cover member (operation ring 30) covering the front body portion 4 and the skirt portion 104 of the rotor 101 can be reduced in diameter, and the fishing spinning reel 100 can be reduced in size.

  In addition, according to the embodiment, since the operation ring 30 surrounds the engagement portion (the protruding portion 27 and the engagement portion 32) between the reverse rotation preventing device 20 and the operation ring 30, only the engagement portion has the small diameter portion 11. It does not have a shape that protrudes from. That is, it can be avoided that the load acts only on the engaging portion and is damaged.

As mentioned above, although embodiment was described, this invention is not limited to this.
For example, since the operation ring 30 of the embodiment is covered with the skirt portion 104 of the rotor 101, the operation ring 30 can be operated by forming the operation knob 33. You may comprise so that it may be exposed from.
According to such a modification, it is not necessary to form the operation knob 33 on the operation ring 30. Therefore, the shape of the operation ring 30 is simplified, and the number of manufacturing steps can be reduced.

Further, in the embodiment, as a configuration for engaging the retainer (switching control member) 24 and the operation ring (cylindrical member) 30 in the circumferential direction, the protruding portion 27 in which the circular hole 28 is formed toward the retainer 24. And the engaging portion 32 is formed toward the operation ring 30, but the present invention is not limited to this.
For example, the protruding portion 27 may be formed on the operation ring 30 and the engaging portion 32 may be formed on the retainer 24.
Alternatively, a concave portion that is recessed radially inward may be formed on the outer peripheral surface of the retainer 24 (annular portion 25), and a convex portion that enters the concave portion may be formed on the inner peripheral surface of the operation ring 30. Even in such a modification, when the operation ring 30 rotates, the convex portion presses the inner surface of the concave portion in the circumferential direction, and the retainer 24 can be rotated.

Moreover, although the operation ring 30 of embodiment is long in the front-back (axis line O) direction and becomes a shape which covers the outer peripheral side of the small diameter part 11, this invention is not limited to this. That is, the cylindrical member (operation ring 30) of the present invention only needs to be able to engage with the protrusion 27, and may be formed short in the front-rear (axis O) direction.
In addition, the present invention may be applied to fishing reels other than fishing spinning reels.
