The detachable member 30 is a restriction position shown in FIG. 11 on the second side face 4d of the first bearing 4 facing the restriction portion 40, and the restriction portion 40 is away from the second side face 4d from the outer side in the axial direction of the restriction position. The remote position shown in Fig. 12 can be moved. The restricting portion 40 is bent and bent linearly from the position of the connecting portion 44 toward the opposing surface of the pressing operation portion 42. Therefore, the regulating portion 40 of one of the detachable members 30 is disposed to face the pressing operation portion 42 of the other detachable member 30 that is disposed at a 180-degree phase. The restricting portion 40 is formed to have a thickness of half of the pressing operation portion 42 and the connecting portion 44. Specifically, the restricting portion 40 is formed to have a thickness of half of the recessed connecting portion 44 of the first surface 30 a of the detachable member 30 . The first surface 30a is a surface that faces the tip end side of the spool shaft when the detachable member 30 is attached to the spool 3. The restricting portion 40 has a regulating surface 40a that faces the second side surface 4d of the first bearing 4, and an inclined surface 40b that is opposite to the regulating surface 40a. The restricting surface 40a is constituted by a plane perpendicular to the spool shaft 2. The inclined surface 40b is constituted by a plane that becomes larger in distance from the outer side in the radial direction and the regulating surface 40a. The regulating surface 40a is a second side surface 4d that is locked to the outer ring 4b of the first bearing 4, and prevents the spool 3 from falling off from the spool shaft 2. When the reel 3 is removed from the spool shaft 2, the inclined surface 40b is in contact with the corner portion of the outer peripheral surface of the outer ring 4b of the first bearing 4, and is attached and detached by tilting. The member 30 is placed in a direction away from the distance. In the outer surface of the restricting portion 40 in the radial direction, the holding projection 40c for holding the pressing member 32 is formed to protrude outward in the radial direction. The restricting portion 40 has a first circular arc portion 40d on the inner peripheral portion. 1st The circular arc portion 40d has an inner diameter slightly larger than the outer diameter of the hub portion 37.

The pressing operation portion 42 is provided to press the detachable member 30 from the restriction position to the outward position in the radial direction. The pressing operation portion 42 is formed to protrude outward from the coupling portion 44 in the radial direction. The inner circumferential surface 42a of the pressing operation portion 42 has an inner diameter slightly larger than the outer circumferential surface of the hub portion 37.

The housing recess 42b is formed in a substantially rectangular recessed shape on the second surface 30b on the opposite side of the first surface 30a of the detachable member 30. The housing recess 42b is formed to be recessed more than half the thickness of the coupling portion.

The connecting portion 44 connects the restricting portion 40 and the pressing operation portion 42. The inner circumferential surface 44a of the coupling portion 44 has a second circular arc portion 44b and a straight portion 44c which are formed to be continuous with the inner circumferential surface 42a of the pressing operation portion 42 and have the same inner diameter. The length of the straight portion 44c is substantially the same as the amount of movement of the detachable member 30. A step surface 44d connected to the linear portion 44c is formed at a boundary portion between the connecting portion 44 and the thin regulating portion 40.

The guide portion 46 is formed to be curved from the pressing operation portion 42 toward the opposite side of the coupling portion 44. The guide portion 46 is provided to guide the pair of detachable members 30 in the radial direction so as to be engaged with the regulating portion 40. The guide portion 46 is formed by the thickness of one half of the joint portion 44. Specifically, the second surface 30b side is recessed by the length of one half of the connecting portion. Thereby, the regulating portion 40 of the other detachable member 30 is in contact with the guiding portion. The guide portion 46 has a guide surface 46a that is in contact with the step surface 44d of the other detachable member 30 at the tip end portion.

The urging member 32 is a coil spring provided in a separate body from the detachable member in this embodiment. One end of the pressing member 32 is a holding protrusion 40c held in the restricting portion 40. The other end of the pressing member 32 is in contact with the housing recess 42b of the other loading and unloading member 30. The pressing member 32 is disposed in a compressed state between one of the attaching and detaching members 30 and the other of the attaching and detaching members 30. Thereby, the pressing member 32 pushes the pair of restricting portions 40 in the approaching direction, that is, the pair of attaching and detaching members 30 toward the restricting position. Therefore, the pair of loading and unloading members 30 are usually disposed at the restricted position.

<Reel handling operation>

In the case of the reel attachment/detachment mechanism 6 having such a configuration, when the reel 3 is unwound from the spool shaft 2, the pair of pressing operation portions 42 of the pair of detachable members 30 are made of, for example, the thumb and the index finger. Grasp. Further, the pair of detachable members 30 are pressed against the urging force of the urging member 32 in a direction in which they approach each other. When the pair of detachable members 30 are pressed, the pair of restricting portions 40 disposed to face the pair of pressing operation portions 42 are directed from the opposite side to the second side face 4d of the first bearing 4 Far away from the first bearing 4 mobile. Thereby, the engagement of the spool shaft 2 of the spool 3 is released. Further, the reel 3 is unwound from the tip end of the spool shaft 2 while the pair of pressing operation portions 42 are pinched. At this time, the first bearing 4 and the second bearing 5 remain on the spool shaft 2.

On the other hand, when the reel 3 which has fallen off from the spool shaft 2 is attached to the spool shaft 2, the spool 3 is attached to the spool shaft 2 from the tip end portion of the spool shaft 2. In this case, the inclined surface 40b of the restricting portion 40 comes into contact with the outer peripheral surface of the outer ring 4b of the first bearing 4 and the corner portion of the first side surface 4c. When the reel 3 is pressed toward the proximal end side of the spool shaft 2 in this state, the inclined surface 40b is pressed by the corner portion, and the pair of detachable members 30 are moved in the radial direction in a direction away from each other. When the regulating surface 40a of the restricting portion 40 exceeds the first bearing 4, the detachable member 30 is returned to the restricted position by the urging member 32. Thereby, the regulating surface 40a is disposed to face the second side surface 4d of the outer ring 4b of the first bearing 4, and is stopped by the spool shaft 2, and the spool 3 is attached to the spool shaft 2.

Here, since the spool 3 can be attached to and detached from the spool shaft 2 by the detachable member 30 that moves in the radial direction, the length of the single-bearing reel 100 in the spool axial direction can be shortened as much as possible.

<Features>

The above embodiment can be expressed as follows.

(A) The reel loading and unloading mechanism 6 is a mechanism for attaching and detaching the reel 3 of the single-bearing reel 100 to the reel shaft 2 by one touch. The reel loading and unloading mechanism 6 is provided with a first bearing 4 as a projection and a pair of mountings The unloading member 30, a pair of pressing members 32, and a cover member 34 as a positioning member. The first bearing 4 is a second side face 4d having the first side face 4c and the opposite side of the first side face 4c. The first bearing 4 is provided separately from the spool shaft 2 on the outer circumferential surface of the spool shaft 2, and is not movable in the axial direction with respect to the spool shaft 2, and is provided at least partially outward in the radial direction, and is the first one with the reel 3 The side surface 4c can abut.

At least one of the attaching and detaching members 30 has a regulating portion 40 and a pressing operation portion 42. The restricting portion 40 faces the second side face 4d of the first bearing 4. The pressing operation portion 42 is provided for the pressing operation.

Set on the reel 3. At least one of the pressing members 32 is provided separately from the attaching and detaching member 30, and urges the attaching and detaching member 30 toward the restricted position. The cover member 34 is positioned at a restricted position by the detachable member 30 that is urged toward the restriction position by the urging member 32.

In the reel loading and unloading mechanism 6, when the reel 3 is unwound from the spool shaft 2, the pressing operation portion 42 is pressed against the urging force of the urging member 32. When the pressing operation portion 42 is pressed, the detachable member 30 moves from the restriction position to the distant position, and the restriction portion 40 is the second side surface 4d that is away from the first bearing 4. Thereby, the reel 3 can be unwound from the spool shaft 2. When the reel 3 is mounted on the spool shaft 2, the reel 3 is attached to the spool shaft in a state where the pressing operation portion 42 is pressed to bring the detachable member 30 to a position away from the position. In this state, when the restriction portion 40 reaches the second side surface 4d of the first bearing 4 beyond the first bearing 4, the hand is moved away from the pressing operation portion 42. open. In this case, the detachable member 30 urged by the urging member 32 is positioned by the cover member 34 and disposed at the restricted position. Thereby, the spool 3 is stopped, and the spool 3 is attached to the spool shaft 2. Here, since the spool 3 can be attached to and detached from the spool shaft 2 by the detaching member 30 that moves in the radial direction, the length of the single-bearing reel in the spool axial direction can be shortened as much as possible. Further, since the first bearing 4 is provided separately from the spool shaft 2, the bearing for rotatably supporting the spool 3 with respect to the spool shaft 2 can be used as a projection. Further, when the projections are integrally provided with the spool shaft 2, the axial length of the projections can be shortened, and the length of the fishing reel in the axial direction can be further shortened.

(B) In the reel attachment/detachment mechanism 6, the detachable member 30 may be a cylindrical boss portion 37 that is attached to the winding rim portion 35 of the reel 3. The boss portion 37 is a pair of slits 37b that penetrate the outer peripheral surface and the inner peripheral surface, and the movement of the spool shaft 2 in the axial direction of the detachable member 30 is restricted by the pair of slits 37b. In this case, the movement of the detachable member 30 in the spool axial direction can be restricted by the pair of slits 37b provided in the hub portion 37.

(C) In the reel attachment mechanism 6, the cover member 34 may be fixed to the tip end portion of the boss portion 37 to position the detachable member 30 at the restriction position. In this case, since the detachable member 30 is positioned at the restricted position by the cover member 34 attached to and detached from the hub portion 37, the positioning of the detachable member 30 is facilitated.

(D) With respect to the reel loading and unloading mechanism 6, the first bearing 4 is provided to protrude in an annular shape. In this case, the first bearing 4 is annularly Since the reel 3 is attached to the spool shaft 2 by any rotation phase, the regulating portion 40 of the detachable member 30 can face the second side surface 4d of the first bearing 4.

(E) In the reel attachment mechanism 6, the first bearing 4 is a rolling bearing in which the tip end of the spool shaft 2 is not movable in the axial direction, and the restriction position is the outer ring of the first bearing 4 opposite to the restriction portion 40. The position of the second side face 4d of 4b is also possible. In this case, since the first bearing 4 for rotatably supporting the reel 3 can be used as a projection, the reel of the reel 3 and the rotation of the reel 3 can be supported by the projection. 2 functions.

(F) With respect to the reel attaching and detaching mechanism 6, the restricting portion 40 and the pressing operation portion 42 are disposed at intervals of 180 degrees. The detachable member 30 may further include a connecting portion 44 that bends and connects the restricting portion 40 and the pressing operation portion 42 outward in the radial direction of the spool shaft 2. In this case, since the restricting portion 40 and the pressing operation portion 42 are disposed at intervals of 180 degrees, and the restricting portion 40 and the pressing operation portion 42 are coupled by the connecting portion 44, the pressing operation portion 42 is brought closer to each other. When the direction of the spool shaft 2 is pressed, the restricting portion 40 moves away from the first bearing 4 toward the distant position.

(G) For the reel loading and unloading mechanism 6, the detachable member 30 may be provided in a pair of 180 degree intervals around the axis of the reel shaft. The pressing operation portion 42 of one of the detachable members 30 is disposed to face the regulating portion 40 of the other detachable member in the radial direction. In this case, since the pressing operation portion 42 of one of the detachable members 30 and the regulating portion 40 of the other detachable member 30 are disposed to face each other in the radial direction, they are easily disposed. The member 32 is urged.

(H) In the reel attachment mechanism 6, the pressing member 32 is provided in a pair, and is disposed in each of the pressing operation portion 42 of the pair of detachable members 30 and the regulating portion 40 of the other detachable member 30. between. In this case, the restriction member 40 can be placed toward the restriction position side only when the pressing members 32 are disposed between the pressing operation portion 42 of the one of the attachment members 30 and the restriction portion 40 of the other attachment member 30. Push.

(I) In the reel attachment mechanism 6, the pressing member 32 may be an elastic system that is disposed between the pressing operation portion 42 and the regulating portion 40 in a compressed state. In this case, the pressing member of the elastic system such as a coil spring can be urged in a direction away from the one pressing operation portion and the other restricting portion.

(J) The reel attachment mechanism (6) has a regulating surface 40a that faces the second side surface 4d and is disposed on the opposite side of the regulating surface 40a and is oriented outward in the radial direction. The inclined surface 40b in which the distance of the regulating surface 40a becomes large may be sufficient. In this case, when the removed reel 3 is mounted on the spool shaft 2, the inclined surface 40b is guided toward the corner on the first side surface 4c side of the first bearing 4, and the detachable member 30 is moved away from the position side. When moving, the restricting portion can easily pass over the protrusion. Therefore, the pressing operation portion 42 does not need to be pressed, and the reel 3 can be attached to the spool shaft 2 only by moving the reel 3 in the axial direction.
