From the state of FIG. 9, the pressing operation portions 42 of the pair of attaching and detaching members 30 face each other. When the pressing operation is performed in the approaching direction, the restricting portion 40 moves outward from the spool shaft 2 in the radial direction. In this manner, the restricting portion 40 can be disengaged from the outer bearing 4b of the first bearing 4. In the state of FIG. 10, since the restriction surface 40 a of the restriction portion 40 is not engaged with the second side surface 4 d, the reel 3 can be detached from the reel shaft 2.

At this time, since the attaching / detaching member 30 is held by the cover member 34, the attaching / detaching member 30 is not detached from the hub portion 37. In addition, one of the holding protrusions 40c enters the other receiving recessed portion 42b, and the pair of attaching and detaching members 30 do not interfere with each other.

In the first embodiment, in a free state in which the ring spring 32 has been opened, the distance between the two engagement portions 32a is closer to each other than the retaining protrusions 40c when the restriction positions 40 of the pair of attachment members 30 are closer to each other. The distance is small. In addition, even if the inner dimensions of the connecting portions 32 are made smaller than the outer diameter of the hub portion 37, the two engaging portions 32a can be separated from each other at positions where the restricting portion 40 is separated from the second side surface 4d.

When the force of the pressing operation by the pressing operation portion 42 is relaxed from the state of FIG. 10, the state of FIG. 9 can be returned by the restoring force of the ring spring 32. In this way, the reel 3 can be mounted on the reel shaft 2. Alternatively, if the reel shaft 2 is inserted into the through hole 37 a of the hub 37 without pressing the pressing operation portion 42 on the reel 3 that has been detached, the attachment member 30 will return to the position shown in FIG. 9. The inclined surface 40 b of the restricting portion 40 abuts a corner portion of the first side surface 4 c of the outer ring 4 b of the first bearing 4. When the hub portion 37 is pushed in in this state, the attaching and detaching member 30 is moved outward in the radial direction by the inclined surface 40b, and the restricting surface 40a can be engaged with the second side surface 4d by sliding on the outer peripheral surface of the outer wheel 4b.

In the roll loading / unloading mechanism 6 according to the first embodiment, the pair of loading / unloading members 30 is elastically pushed toward the rotation axis of the roll 3 by a ring spring 32. The reel attaching and detaching mechanism 6 according to the first embodiment is a state in which a pair of attaching and detaching members 30 are arranged in the slits 37 b of the hub portion 37, and only the ring spring 32 is fitted into the holding protrusion 40 c of the attaching and detaching member 30. Assemble.

The ring spring 32 is not limited to the shape shown in FIG. 7. For example, it is not limited to a wire, and it can also be formed by processing from a plate-shaped material. As described above, the gap 32c may or may not be provided. For example, the wire 32 may be processed to form a shape as shown in FIG. 7, and then the gap 32 c may be fused and connected. The engaging portion 32a is not limited to the engaging portion 32a formed by bending, but may be formed by insert molding, for example. The "ring" of the ring spring does not mean to surround the entire periphery. For example, a structure may be adopted in which the two engaging portions 32a are not connected by the two connecting portions 32b, but the engaging portions 32b are connected by one of the connecting portions 32b. In this case, no gap 32c is formed in any of the two engaging portions 32a, and a portion where the connecting portion 32b is omitted corresponds to the gap 32c.

In addition, instead of being fixed to the hub portion 37 by the screw portion 34a, the cover member 34 may be formed in the cover member 34 with an annular recessed portion that engages with an annular convex portion formed in the hub portion 37 and elastically deforms it. Construct the embedding.

The positioning protrusions 48 of the attaching and detaching member 30 are not limited to the shapes shown in FIGS. 5 and 6. The positioning protrusion 48 may not be provided. In this case, the ring spring 32 is in contact with the cover member 34, and the attaching and detaching member 30 is held indirectly via the ring spring 32.

[Embodiment 2] Fig. 11 is a perspective view of a ring spring according to Embodiment 2 of the present invention. In the second embodiment, the roll loading / unloading mechanism 6 includes only one loading / unloading member 30.

The ring spring 32 according to the second embodiment is one in which one engagement portion 32 a of a pair of engagement portions 32 a of the ring spring 32 according to the first embodiment is replaced to form a fitting portion 32 d. The fitting portion 32 d is fitted into the slit 37 b of the hub portion 37. The ring spring 32 of FIG. 11 is also formed with a gap 32c. The gap 32c may be formed not in the engaging portion 32a but in the fitting portion 32d. The ring spring 32 may have an endless ring shape without a gap 32c.

Fig. 12 is a sectional view of a roll loading and unloading mechanism according to a second embodiment. FIG. 12 is a cross-sectional view taken along the line IX-IX of FIG. 3, similarly to FIG. 9. In the second embodiment, one attachment member 30 is attached to the hub portion 37. The engaging portion 32a of the ring spring 32 is engaged with the holding protrusion 40c. The fitting portion 32 d is fitted to the other slit 37 b opposite to the slit 37 b into which the restricting portion 40 is inserted.

In the second embodiment, as shown in FIG. 12, the ring spring 32 is formed so that the restricting portion 40 is elastically pushed toward the spool shaft 2. The restricting portion 40 enters the through hole 37a from the through portion of the slit 37b, and is engaged with the second side surface 4d of the outer ring 4b.

In the second embodiment, the ring-shaped spring 32 can be attached from the front end side of the hub portion 37 while the attachment member 30 is attached to the hub portion 37 and held in the restricted position. After the ring spring 32 is attached, the cover member 34 is attached. The cover member 34 covers the attaching and detaching member 30 and the ring spring 32 in addition to the pressing operation portion 42, and only the pressing operation portion 42 can be seen from the front end side of the roll 3 (see FIG. 1).

From the state of the restricted position, by placing a finger opposite to the pressing operation portion 42 across the rotation axis of the cover member 34 and pressing the pressing operation portion 42 toward the reel shaft 2, the restricting portion 40 can be moved from the first 2 side 4d detached. At this time, the fitting portion 32d of the ring-shaped spring 32 is pressed by the connection portion 44 and the guide portion 46, and does not come off the slit 37b.

In the second embodiment, the number of parts is small, and assembly can be performed more easily. It is to be noted that the “ring” of the ring spring does not mean to surround the entire periphery. For example, a structure may be adopted in which the engaging portion 32a and the fitting portion 32d are not connected by the two connecting portions 32b, but the engaging portion 32a and the fitting portion 32d are connected by one of the connecting portions 32b. In this case, no gap 32c is formed in either the engaging portion 32a or the fitting portion 32d, and a portion where the connecting portion 32b is omitted corresponds to the gap 32c.

[Embodiment 3] FIG. 13 is a cross-sectional view of a roll loading and unloading mechanism according to Embodiment 3 of the present invention. In Embodiment 3, instead of directly pushing the restricting portion 40 with the ring spring 32, the ring spring 32 pushes the pressing operation portion 42 outward in the radial direction, and indirectly pushes the restricting portion 40 inward in the radial direction. .

In the third embodiment, the attaching and detaching member 30 has a holding protrusion 42c inside the pressing operation portion 42 instead of the holding protrusion 40c. The ring spring 32 of the third embodiment has the same shape as the ring spring 32 of FIG. 7, but the distances between the engagement portions 32 a are different. In the third embodiment, the distance between the two engagement portions 32a is larger than the distance between the holding protrusions 42c when the restriction portions 40 of the pair of attachment members 30 are located close to each other in the free state that has been opened. . In addition, even if the inner dimensions of the connecting portions 32 are smaller than the outer diameter of the hub portion 37, the two engaging portions 32a can be separated from each other at a position where the restricting portion 40 engages with the second side surface 4d. Therefore, the pair of attaching and detaching members 30 can be maintained in the state shown in FIG. 13, and the ring spring 32 can be attached from the front end side of the hub portion 37.

As shown in FIG. 13, the ring spring 32 is held by being engaged with a holding protrusion 42 c formed inside the pressing operation portion 42. In the free state in which the ring spring 32 has been opened, the distance between the two engaging portions 32a is larger than the distance between the holding protrusions 42c when the pair of attachment and detachment members 30 are in the restricted position. Therefore, in the state shown in FIG. Next, the pressing operation portions 42 are pushed and pushed in a direction away from each other.

In the pair of attaching and detaching members 30, the respective restricting portions 40 are disposed opposite to the pressing operation portion 42 across the rotation axis of the reel 3. Therefore, if the pressing operation portion 42 is pushed and pushed away from the rotation axis, , The restricting portion 40 is elastically pushed in a direction approaching the rotation axis. Therefore, the operation of the pair of attachment / detachment members 30 is the same as that of the first embodiment.

In a state where the pair of attaching and detaching members 30 are attached to the slit 37 b of the hub portion 37 and held at the position shown in FIG. 13, the ring spring 32 is fitted into the engaging portion 32 a from the front end side of the hub portion 37 It engages with the holding protrusion 42c. In a free state in which the ring spring 32 has been opened, the distance between the two engagement portions 32 a is larger than the distance between the holding protrusions 42 c when the pair of attachment members 30 is in the restricted position. When the connecting portions 32b are expanded and separated from each other, the engaging portions 32b can be compressed to be close to each other. Alternatively, the engaging portions 32a may be compressed to approach each other immediately. When the engaging portions 32a are compressed so as to be close to each other, inserting the engaging portions 32a into the storage recesses 42b and relaxing the force for expanding the connecting portions 32b to each other can cause the two engaging portions 32a to be engaged with each other. The projection 42c is held.

Fig. 14 is a sectional view of the roll loading and unloading mechanism during a pressing operation according to the third embodiment. FIG. 14 is a cross-sectional view taken along the line IX-IX of FIG. 3, similarly to FIG. 9. FIG. 14 shows a state where the attachment / detachment member 30 is in the disengaged position.

In the pair of attaching and detaching members 30, the respective restricting portions 40 are positioned opposite to the pressing operation portion 42 with the reel shaft 2 interposed therebetween. From the state of FIG. When the pressing operation is performed in the directions approaching each other, the restricting portion 40 moves outward from the spool shaft 2 in the radial direction. In this manner, the restricting portion 40 can be disengaged from the outer bearing 4b of the first bearing 4. In the state of FIG. 14, the restricting surface 40 a of the restricting portion 40 is not engaged with the second side surface 4 d, and therefore, the roll 3 can be detached from the roll shaft 2. At this time, since the attaching / detaching member 30 is held by the cover member 34, the attaching / detaching member 30 is not detached from the hub portion 37.

In Embodiment 3, the ring spring 32 may not surround the entire circumference. For example, a structure may be adopted in which the two engaging portions 32a are not connected by the two connecting portions 32b, but the engaging portions 32b are connected by one of the connecting portions 32b. In this case, no gap 32c is formed in the engaging portion 32a, and a portion where the connecting portion 32b is omitted corresponds to the gap 32c.

[Embodiment 4] FIG. 15 is a cross-sectional view of a roll loading and unloading mechanism according to Embodiment 4 of the present invention. FIG. 15 is a cross-sectional view taken along the line IX-IX in FIG. 3. The fourth embodiment is a structure in which the attaching and detaching member and the ring spring are integrated.

The ring spring 33 according to the fourth embodiment has a function of attaching and detaching the member 30 and the ring spring 32. The ring spring 33 is constituted by a ring-shaped spring member. The ring spring 33 includes two restricting portions 50 and two pressing operation portions 33b. The two restriction portions 50 are arranged at positions where the ring springs 33 face each other. The two pressing operation portions 33b are disposed at positions of the ring springs 33 facing each other. The line connecting the restriction portions 50 to each other is orthogonal to the line connecting the pressing operation portions 33b to each other. Compared with the ring spring 32 of the first embodiment, the restricting portion 50 corresponds to the engaging portion 32a, and the pressing operation portion 33b corresponds to the connecting portion 32b.

In a state where the ring spring 33 has been opened, the internal dimensions of the two restriction portions 50 relative to each other are smaller than the inner diameter of the outer ring 4 b of the first bearing 4. In the state of FIG. 15, from the state in which the ring spring 33 has been opened, the restricting portions 50 are isolated from each other. Therefore, the restricting portions 50 are elastically pushed toward each other. The inner periphery of the ring-shaped spring 33 is in contact with the corner of the notch surface 37c of the slit 37b and is stable.

The ring springs 33 are arranged in a direction in which the pressing operation portions 33b are brought closer to each other, that is, when the rotating shaft of the reel 3 is pressed, the restricting portions 50 are isolated from each other. That is, the restriction portion 50 is moved in a direction to be detached from the second side surface 4d of the outer wheel 4b.

Fig. 16 is a sectional view of a roll loading and unloading mechanism when a ring spring is mounted in the fourth embodiment. FIG. 16 is a cross-sectional view taken along the line IX-IX of FIG. 3, similarly to FIG. 15. The length of the imaginary inner periphery VC of the annular spring 33 passing through the radially inner end of the restriction portion 50 in the radial direction and the radial inner periphery of the pressing operation portion 33b is greater than the length of the outer periphery of the cross section of the hub 37. Therefore, as shown in FIG. 16, when the pressing operation portions 33 b are pressed toward each other, they can be deformed and inserted into the hub portion 37. When the deformation of the ring spring 33 is returned to the original position at the position of the slit 37b, as shown in FIG. 15, the ring spring 33 can be installed at the restricted position.

After the ring-shaped spring 33 is attached to the slit 37 b, the cover member 34 is attached to the front end of the hub portion 37. If the outer diameter of the cover member 34 is made larger than the outer dimensions of the pressing operation portions 33b when the ring spring 33 is installed, the distance between the restricting portions 50 from the outside of the cover member 34 is increased until it becomes larger than the hub. Until the ring spring 33 cannot be deformed until the outer diameter of the portion 37 is large, the ring spring 33 cannot be removed. When the pressing operation portions 33 b have been pressed to each other, the curved portion abutting the outer periphery of the cover member 34 may be formed in the ring spring 33.

Fig. 17 is a perspective view showing an example of a ring spring according to the fourth embodiment. The ring spring 33 of FIG. 17 is formed, for example, by inserting the ring-shaped spring into the molding restriction portion 50. The ring-shaped spring system is, for example, the ring-shaped spring 32 of FIG. 7, and can be formed by processing a single wire. When the ring-shaped spring has a gap 32c, the gap 32c can be disposed in the restriction portion 50 that is subjected to insert molding. In addition, when the ring-shaped spring is bent in the restricting portion 50 in advance, the restricting portion 50 does not roll around the spring material.

In the ring spring 33 of FIG. 17, the pressing operation portion 33 is formed as a curved portion standing up from the surface of the ring spring. In a state where the ring spring 33 is mounted on the hub portion 37 and then the cover member 34 is mounted, the distance between the pressing operation portions 33 cannot be made smaller than the outer diameter of the cover member 34. As a result, the ring spring 33 is held by the cover member 34.

The restricting portion 50 includes a restricting surface 50 a arranged opposite to the second side surface 4 d of the first bearing 4, and an inclined surface 50 b on the opposite side of the restricting surface 50 a. The regulating surface 50 a is configured by a plane orthogonal to the rotation axis of the roll 3. The inclined surface 50b is formed by a plane that faces outward in the radial direction and has a larger distance from the restricting surface 50a. The restricting surface 50 a is locked to the second side surface 4 d of the outer ring 4 b of the first bearing 4 to prevent the reel 3 from falling off the reel shaft 2. The inclined surface 50b is designed to contact the corner portion of the outer peripheral surface of the outer ring 4b of the first bearing 4 when the reel 3 separated from the reel shaft 2 is mounted on the reel shaft 2, and the restriction portion 50 is inclined toward the It is set by pressing in the separated direction.

In the reel loading / unloading mechanism 6 according to the fourth embodiment, since the loading / unloading member is integrated with the ring spring, the number of parts can be further reduced, and assembly can be performed more easily.

In the foregoing embodiment, the first bearing 4 of the rolling bearing was described as an example of the protrusion, but the present invention is not limited to this. The protrusion may be a plain bearing. Also, the protrusion may be formed integrally with the spool shaft. In particular, when the protrusion is made of synthetic resin, even if the protrusion also serves as a bearing, the protrusion can be easily provided integrally with the spool shaft. Also, the protrusion may be integrally provided with the spool shaft by a molding method such as insert molding.

In the embodiment, the single bearing reel 100 provided with a handle 54 on the reel 3 has been described.
