Therefore, for the attachment/detachment member 30 engaged with the second side surface 4d, the movement of the spool 3 in the axial direction is restricted by the slit 37b.

<The structure of the reel loading and unloading mechanism> 　　 Figure 5 is a front view of the loading and unloading member of the first embodiment. Fig. 6 is a perspective view of the attachment and detachment member of the first embodiment. The attachment and detachment member 30 is a member formed by bending substantially into a C shape. The attaching and detaching member 30 has a restricting portion 40, a pressing operation portion 42, a connecting portion 44, and a guide portion 46. The attachment/detachment member 30 is attached to the slit 37b of the spool 3 so that the first surface 30a faces the front end side of the spool shaft 2. The restricting portion 40 is formed in a linear shape after being bent from the connecting portion 44 to a position opposed to the pressing operation portion 42.

The restricting portion 40 has a restricting surface 40a arranged opposite to the second side surface 4d of the first bearing 4, and an inclined surface 40b on the opposite side of the restricting surface 40a. The restriction surface 40a is constituted by a plane orthogonal to the rotation axis of the reel 3. The inclined surface 40b is constituted by a plane whose distance from the restriction surface 40a increases toward the outside in the radial direction. The restriction surface 40a is locked to the second side surface 4d of the outer ring 4b of the first bearing 4, and prevents the spool 3 from detaching from the spool shaft 2. The inclined surface 40b is designed to contact the corners of the outer peripheral surface of the outer ring 4b of the first bearing 4 when the spool 3 detached from the spool shaft 2 is mounted to the spool shaft 2, and the pair of attachment and detachment members are slanted. 30 is set by pressing in the direction of separation. On the outer side surface in the radial direction of the restricting portion 40, a holding protrusion 40c for holding the ring spring 32 is formed to protrude outward in the radial direction. The restricting portion 40 has a first cylindrical surface 40d in the inner peripheral portion. The inner diameter of the first cylindrical surface 40 d is slightly larger than the outer diameter of the hub 37.

The pressing operation part 42 is provided in order to perform the pressing operation which moves the attaching and detaching member 30 from the restriction|limiting position to the disengagement position to the radial direction outer side. The pressing operation portion 42 is formed to protrude outward in the radial direction from the connection portion 44. The pressing operation portion 42 is formed with a storage recess 42b, which is a holding protrusion 40c for receiving the other attachment/detachment member 30 when the two attachment/detachment members 30 are arranged to face each other. The storage recessed portion 42b is formed by being recessed in a substantially rectangular shape from the inner peripheral surface 44a of the connecting portion 44 toward the outer side in the radial direction.

The connecting portion 44 connects the restricting portion 40 and the pressing operation portion 42. The inner peripheral surface 44a of the connecting portion 44 has a second cylindrical surface 44b whose inner diameter is slightly larger than the outer peripheral surface of the hub portion 37, and a flat surface portion 44c. The length of the flat portion 44c is substantially the same as the movement amount of the attaching and detaching member 30. The boundary portion between the connecting portion 44 and the thin restricting portion 40 is formed with a step surface 44d in which the flat portion 44c extends linearly.

The guide portion 46 is formed by bending from the pressing operation portion 42 to the side opposite to the connecting portion 44. The guide portion 46 is provided to guide the pair of attaching and detaching members 30 to each other in the radial direction in order to engage with the restricting portion 40. The sum of the thickness of the restricting portion 40 and the thickness of the guiding portion 46 is equivalent to the thickness of the connecting portion 44. If the two attaching and detaching members 30 are arranged such that their respective restricting portions 40 face each other, one restricting portion 40 will overlap below the other guiding portion 46, and one restricting portion 40 will be blocked by the other guiding portion 46. guide. The guide part 46 has a guide surface 46a in parallel contact with the step surface 44d of the other attaching and detaching member 30 at the front-end|tip part. The inner peripheral surface 46b of the guide portion 46 has the same inner diameter as the second cylindrical surface 44b, and overlaps the extension line of the second cylindrical surface 44b.

On the first surface 30a of the attaching and detaching member 30, a positioning protrusion 48 that is in contact with the cover member 34 is formed to protrude from the first surface 30a. The positioning protrusion 48 is formed to avoid the ring spring 32. When the positioning protrusion 48 abuts on the cover member 34, the attaching and detaching member 30 is held by the hub 37.

Fig. 7 is a perspective view of the ring spring of the first embodiment. The ring spring 32 has two engaging portions 32a that engage with the holding protrusion 40c of the attaching and detaching member 30 and oppose each other, and two connecting portions that connect the engaging portions 32a and oppose each other. 32b. The ring spring 32 is formed of a wire. In Embodiment 1, the ring spring 32 is not an endless ring, but is cut by a gap 32c at one place. Here, a spring having a gap 32c instead of an endless ring is also referred to as a ring spring. The ring spring 32 may also have an endless ring shape without a gap 32c.

If the ring spring 32 isolates the engaging parts 32a from each other from the opened free state, there will be a force acting to push the engaging parts 32a toward each other in the approaching direction. In addition, if the connecting portions 32b are compressed to be close to each other, the engaging portions 32b can be expanded to be separated from each other.

Conversely, if the engaging portions 32a are brought close to each other from the opened free state, there will be a force acting to push the engaging portions 32a away from each other. In addition, if the connecting portions 32b are expanded to be apart from each other, the engaging portions 32b can be brought close to each other.

Fig. 8 is a perspective view of a pair of attachment and detachment members of the first embodiment. FIG. 8 shows that a pair of attaching and detaching members 30 are mounted on the hub 37, and only the attaching and detaching members 30 are shown in a restricted position. In FIG. 8, the positioning protrusion 48 is omitted.

In the state of FIG. 8, the restricting portion 40 is fitted into the slit 37 b of the hub 37, and the restricting surface 40 a is located at a position that engages with the second side surface 4 d of the first bearing 4. In this state, the first cylindrical surface 40d of the restricting portion 40 abuts on the outer peripheral surface of the hub 37, and the restricting portions 40 do not come close to each other from the state of FIG. 8.

In the state where the pair of attaching and detaching members 30 are installed in the slit 37b of the hub 37 and held at the position shown in FIG. 8, from the front end side of the hub 37, that is, from the upper side in FIG. The shaped spring 32 is fitted so that the engaging portion 32a is engaged with the holding protrusion 40c. In the free state where the ring spring 32 is opened, the mutual distance between the two engagement portions 32a is smaller than the mutual distance between the holding protrusions 40c when the restriction portions 40 of the pair of attaching and detaching members 30 are located close to each other. If the connecting portions 32b are compressed so as to be close to each other, the engaging portions 32b can be enlarged to be separated from each other. When the engaging portions 32a are enlarged to be separated from each other, the engaging portion 32a is inserted into the accommodating recess 42b, and the force compressing the connecting portions 32b is relaxed, so that the two engaging portions 32a can be engaged with the holding protrusions. 40c.

After the ring spring 32 is installed, the cover member 34 is installed. 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 is visible from the front end side of the spool 3 (refer to FIG. 1).

Figure 9 is a cross-sectional view of the reel loading and unloading mechanism of the first embodiment. Fig. 9 shows the cross section of the IX-IX cutting line in Fig. 3. The pair of attaching and detaching members 30 are arranged so that the spool shaft 2 is interposed, and the respective restricting portions 40 are opposed to each other. Fig. 9 shows a state where the loading and unloading member 30 is in a restricting position.

The restricting portion 40 of the attaching and detaching member 30 is arranged in the slit 37 b of the hub 37. The guide portion 46 of the one attaching and detaching member 30 is located on the back side of the paper surface than the other restricting portion 40 and is in contact with the restricting surface 40 a of the restricting portion 40. The ring spring 32 is held by the holding protrusion 40 and urges the restricting portion 40 toward the spool shaft 2, respectively.

In the state of FIG. 9, the first cylindrical surface 40d of the restricting portion 40 is in contact with the outer peripheral surface of the hub 37, or the linear portion on the side of the connecting portion 44 of the restricting portion 40 is in contact with the notch surface 37c of the hub 37 . The restricting portion 40 enters the through hole 37a of the hub 37 from the penetrating portion of the slit 37b, and the restricting surface 40a is engaged with the second side surface 4d of the outer ring 4b. The attachment/detachment member 30 restricts the movement of the spool 3 in the axial direction by the slit 37b. Therefore, for the attachment/detachment member 30 engaged with the second side surface 4d, the movement of the spool 3 in the axial direction is restricted by the slit 37b.

With the respective attachment and detachment members 30, the pressing operation portion 42 is at a position opposed to the restricting portion 40 with the spool shaft 2 interposed therebetween. The restricting portion 40 is urged toward the spool shaft 2 by the ring spring 32 and is located close to the spool shaft 2. Therefore, the pressing operation portion 42 is at a position away from the spool shaft 2.

Figure 10 is a cross-sectional view of the reel loading and unloading mechanism during the pressing operation of the first embodiment. Fig. 10 shows the cross section of the IX-IX cutting line of Fig. 3 in the same manner as Fig. 9. Fig. 10 shows a state where the attaching and disassembling member 30 is in the disengaged position.

In the respective attaching and detaching members 30, the restricting portion 40 is at a position facing the pressing operation portion 42 across the spool shaft 2. 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 from the spool shaft 2 to the outer side in the radial direction. In this way, the restricting portion 40 can be separated from the outer ring 4b of the first bearing 4. In the state of FIG. 10, the restriction surface 40 a of the restriction portion 40 is not engaged with the second side surface 4 d, and therefore, the spool 3 can be detached from the spool shaft 2.

At this time, the attaching and detaching member 30 is held by the cover member 34, and therefore, will not be separated from the hub 37. In addition, the holding protrusion 40c on one side enters the receiving recess 42b on the other side, and there is no possibility that the pair of attaching and detaching members 30 interfere with each other.

In the first embodiment, in the free state where the ring spring 32 is opened, the mutual distance between the two engagement portions 32a is the mutual distance between the holding protrusions 40c when the restriction portions 40 of the pair of attaching and detaching members 30 are closer to each other. The distance is small. Furthermore, even if the inner dimensions of the connecting portions 32 are made smaller than the outer diameter of the hub 37, the two engaging portions 32a can be separated from each other toward the position where the restricting portion 40 is separated from the second side surface 4d.

From the state of FIG. 10, if the force for pressing the pressing operation portion 42 is relaxed, the restoring force of the ring spring 32 can return to the state of FIG. 9. In this way, the reel 3 can be installed on the reel shaft 2. Alternatively, if the reel shaft 2 is inserted into the through hole 37a of the hub 37 without pressing the pressing operation portion 42 in the spool 3 that has been detached, the attaching and detaching member 30 will return to the position of FIG. 9. , The inclined surface 40b of the restricting portion 40 abuts the corner of the first side surface 4c of the outer ring 4b of the first bearing 4. If the hub 37 is press-fitted in this state, the attachment/detachment member 30 is moved radially outward by the inclined surface 40b, and slides on the outer peripheral surface of the outer ring 4b, so that the restriction surface 40a can be engaged with the second side surface 4d.

In the reel attaching and detaching mechanism 6 of the first embodiment, the pair of attaching and detaching members 30 are urged toward the rotation axis of the reel 3 by one ring spring 32. The reel attaching and detaching mechanism 6 of the first embodiment is a state in which a pair of attaching and detaching members 30 are arranged in the slit 37b of the hub 37, and only the ring spring 32 is fitted to the holding protrusion 40c of the attaching and detaching member 30. Assemble.

In addition, the ring spring 32 is not limited to the shape of FIG. 7. For example, it is not limited to a wire, and it may be formed by processing from a plate-shaped material. As mentioned above, there may be a gap 32c or no gap 32c. For example, after a wire is processed to form a shape as shown in FIG. 7, the gap 32c may be welded and connected. It is not limited to the engaging portion 32a formed by bending, and the engaging portion 32a may be formed by insert molding, for example. In addition, the "ring" of the ring spring does not mean encompassing the entire circumference. For example, instead of connecting the two engaging portions 32a by the two connecting portions 32b, it may be a structure in which the engaging portion 32b is connected by one of the connecting portions 32b. In this case, the gap 32c is not formed in the two engagement portions 32a, and the portion where the connection portion 32b is omitted corresponds to the gap 32c.

In addition, the cover member 34 may not be fixed to the hub 37 by the screw portion 34a, but, for example, a ring-shaped concave portion that is engaged with the ring-shaped convex portion formed on the hub portion 37 is formed in the cover member 34 to be elastically deformed. Carry out the embedded structure.

The positioning protrusion 48 of the attaching and detaching member 30 is not limited to the shape shown in FIGS. 5 and 6. In addition, 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 reel loading and unloading mechanism 6 includes only one loading and unloading member 30.

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

Figure 12 is a cross-sectional view of the reel loading and unloading mechanism of the second embodiment. Fig. 12 shows the cross section of the IX-IX cutting line of Fig. 3 in the same manner as Fig. 9. In the second embodiment, one attaching and detaching member 30 is attached to the hub 37. The engaging portion 32a of the ring spring 32 is engaged with the holding protrusion 40c. In addition, the fitting portion 32d is fitted to the other slit 37b facing the slit 37b into which the restricting portion 40 is inserted.

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

In the second embodiment, in a state where the attaching and detaching member 30 is attached to the hub 37 and held at the restricting position, the ring spring 32 can be attached from the front end side of the hub 37. After the ring spring 32 is installed, the cover member 34 is installed. 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 is visible from the front end side of the spool 3 (refer to FIG. 1).

From the state of the restriction position, place your finger at a position opposite to the pressing operation portion 42 via the rotation axis of the cover member 34, and press the pressing operation portion 42 toward the spool shaft 2, thereby allowing the restriction portion 40 to move from the first position. 2 Side 4d is detached. At this time, the fitting portion 32d of the ring spring 32 is pressed by the connecting portion 44 and the guide portion 46 so as not to be separated from the slit 37b.

In the second embodiment, the number of parts is small, and the assembly can be performed more easily. In addition, the "ring" of the ring spring does not mean to encompass the entire circumference. For example, instead of connecting the engaging portion 32a and the fitting portion 32d by two connecting portions 32b, a structure may be adopted in which the engaging portion 32a and the fitting portion 32d are connected by one of the connecting portions 32b. In this case, the gap 32c is not formed in neither the engaging portion 32a nor the fitting portion 32d, and the portion where the connecting portion 32b is omitted corresponds to the gap 32c.

[Embodiment 3] 　　 Fig. 13 is a cross-sectional view of a reel loading and unloading mechanism in Embodiment 3 of the present invention. In Embodiment 3, the ring spring 32 does not directly push the restricting part 40, but the ring spring 32 pushes the pressing operation part 42 radially outward, and the restricting part 40 indirectly pushes the restricting part 40 radially inward. .

In the third embodiment, the attaching and detaching member 30 has a holding protrusion 42c on the inner side of 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 engaging portions 32a are different. In the third embodiment, in the opened free state, the mutual distance between the two engagement portions 32a is greater than the mutual distance between the holding protrusions 42c when the restriction portions 40 of the pair of attaching and detaching members 30 are located close to each other. . Furthermore, even if the inner dimensions of the connecting portions 32 are made smaller than the outer diameter of the hub 37, the two engaging portions 32a can be separated from each other at the position where the restricting portion 40 is engaged with the second side surface 4d. Therefore, the pair of attachment and detachment members 30 can be held in the state shown in FIG. 13, and the ring spring 32 can be attached from the front end side of the hub 37.

As shown in FIG. 13, the ring spring 32 is engaged with and held by a holding protrusion 42 c formed on the inner side of the pressing operation portion 42. In the free state where the ring spring 32 has been opened, the mutual distance between the two engagement portions 32a is greater than the mutual distance between the holding protrusions 42c when the pair of attaching and detaching members 30 are in the restricted position. Therefore, in the state of FIG. 13 Next, the pressing operation parts 42 are pushed in the direction of separating each other.

In the pair of attaching and detaching members 30, the respective restricting portions 40 are arranged at positions opposite to the pressing operation portion 42 via the rotation axis of the reel 3, so if the pressing operation portion 42 springs in the direction separating from the rotation axis , The restricting portion 40 is pushed in a direction approaching the rotation axis. Therefore, the operation of the pair of attaching and detaching members 30 is the same as that of the first embodiment.

In the state where the pair of attaching and detaching members 30 are installed in the slit 37b of the hub 37 and held in the position shown in FIG. 13, from the front end side of the hub 37, the ring spring 32 is fitted into the engagement portion 32a It engages with the holding protrusion 42c. In the free state where the ring spring 32 is opened, the mutual distance between the two engagement portions 32a is greater than the mutual distance between the holding protrusions 42c when the pair of attaching and detaching members 30 are in the restricted position. If the connecting portions 32b are expanded to be separated from each other, the engaging portions 32b can be compressed so as 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 that the engaging portions 32a are close to each other, the engaging portion 32a is inserted into the accommodating recess 42b, and the force that expands the connecting portions 32b to each other is relaxed, so that the two engaging portions 32a can be engaged with each other. Hold the protrusion 42c.

Fig. 14 is a cross-sectional view of the reel loading and unloading mechanism during the pressing operation of the third embodiment. Fig. 14 shows the cross section of the IX-IX cutting line of Fig. 3 in the same manner as Fig. 9. Fig. 14 shows a state where the attaching and dismounting member 30 is in the disengaged position.

In the pair of attaching and detaching members 30, the respective restricting portions 40 are in positions opposite to the pressing operation portion 42 via the spool shaft 2, and the pressing operation portions 42 of the pair of attaching and detaching members 30 are directed from the state of FIG. When the pressing operation is performed in the directions approaching each other, the restricting portion 40 moves from the spool shaft 2 to the radially outer side. In this way, the restricting portion 40 can be separated from the outer ring 4b of the first bearing 4. In the state of FIG. 14, the restriction surface 40 a of the restriction portion 40 is not engaged with the second side surface 4 d, and therefore, the spool 3 can be separated from the spool shaft 2. At this time, the attaching and detaching member 30 is held by the cover member 34, and therefore, will not be separated from the hub 37.

In the third embodiment, the ring spring 32 does not need to surround the entire circumference. For example, instead of connecting the two engaging portions 32a by the two connecting portions 32b, it may be a structure in which the engaging portion 32b is connected by one of the connecting portions 32b. In this case, the gap 32c is not formed in the engagement portion 32a, and the portion where the connection portion 32b is omitted corresponds to the gap 32c.

[Embodiment 4] 　　 Fig. 15 is a cross-sectional view of a reel loading and unloading mechanism according to Embodiment 4 of the present invention. Fig. 15 shows the cross section of the IX-IX cutting line in Fig. 3. The fourth embodiment is a structure in which the attachment and detachment member and the ring spring are integrated.

The ring spring 33 of the fourth embodiment has the functions of the attaching and detaching member 30 and the ring spring 32. The ring spring 33 is composed of a ring-shaped spring member. The ring spring 33 has two restricting parts 50 and two pressing operation parts 33b. The two restricting portions 50 are arranged at positions facing each other of the ring spring 33. In addition, the two pressing operation portions 33b are arranged at positions where the ring spring 33 opposes each other. The line connecting the restricting 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 is opened, the mutual inner dimension of the two restricting portions 50 is smaller than the inner diameter of the outer ring 4b of the first bearing 4. In the state of FIG. 15, since the ring spring 33 has been opened, the restricting portions 50 are separated from each other, and therefore, the restricting portions 50 are urged in the direction of approaching each other. The inner circumference of the ring spring 33 is in contact with the corner of the notch surface 37c of the slit 37b and stabilized.

The ring-shaped spring 33 is directed in the direction in which the pressing operation portions 33b approach each other, that is, when the rotation shaft of the reel 3 is pressed, the restricting portions 50 are separated from each other. That is, the restricting portion 50 is moved in a direction to escape from the second side surface 4d of the outer ring 4b.

Fig. 16 is a cross-sectional view of the reel mounting and dismounting mechanism when the ring spring is installed in the fourth embodiment. Fig. 16 shows the cross section of the IX-IX cutting line of Fig. 3 in the same way as Fig. 15. The length of the virtual inner circumference VC of the ring spring 33 passing through the radially inner front end of the restricting portion 50 and the radially inner circumference of the pressing operation portion 33b is greater than the length of the outer circumference of the cross section of the boss 37. Therefore, if the pressing operation parts 33b are pressed in the direction of approaching each other, as shown in FIG. 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 in the restricting position.

After the ring spring 33 is installed in the slit 37 b, the cover member 34 is installed on the front end of the hub 37. If the outer diameter of the cover member 34 is made larger than the outer size of the pressing operation parts 33b when the ring spring 33 is installed, the distance between the restricting parts 50 from the outside of the cover member 34 is increased until it becomes more hub. If the ring spring 33 cannot be deformed until the outer diameter of the portion 37 becomes large, the ring spring 33 cannot be removed. When the pressing operation parts 33b have been pressed against each other, the curved part abutting on the outer circumference of the cover member 34 may be formed in the ring spring 33.

Fig. 17 is a perspective view showing an example of the ring spring of the fourth embodiment. The ring-shaped spring 33 of FIG. 17 is formed by inserting and molding a ring-shaped spring into the restricting portion 50, for example. The ring-shaped spring system, for example, like the ring-shaped spring 32 of FIG. 7, can be formed by processing one wire. When the ring-shaped spring has a gap 32c, the gap 32c may be arranged in the restricting portion 50 for insert molding. In addition, if the ring-shaped spring is bent in the restricting portion 50 in advance, the restricting portion 50 will 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 rising from the surface of the ring spring. In the state where the ring spring 33 is mounted on the hub 37 and the cover member 34 is mounted, the distance between the pressing operation parts 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 has a restricting surface 50a arranged opposite to the second side surface 4d of the first bearing 4, and an inclined surface 50b on the opposite side of the restricting surface 50a. The restriction surface 50a is constituted by a plane orthogonal to the rotation axis of the reel 3. The inclined surface 50b is formed by a plane whose distance from the restriction surface 50a increases toward the outside in the radial direction. The restriction surface 50a is locked to the second side surface 4d of the outer ring 4b of the first bearing 4 to prevent the spool 3 from falling off the spool shaft 2. The inclined surface 50b is designed to contact the corner of the outer circumferential surface of the outer ring 4b of the first bearing 4 when the spool 3 separated from the spool shaft 2 is mounted to the spool shaft 2, and the restricting portion 50 is inclined toward Set by pressing in the direction of separation.

In the reel attachment and detachment mechanism 6 of the fourth embodiment, since the attachment and detachment member and the ring spring are formed integrally, the number of parts can be further reduced, and the assembly can be more easily performed.

In the foregoing embodiment, the first bearing 4 of the rolling bearing has been described as an example of the protrusion, but the present invention is not limited to this. The protrusion may also be a sliding bearing. In addition, the protrusion may be formed integrally with the spool shaft. Especially when the protrusion is made of synthetic resin, even if the protrusion is also used as a bearing, the protrusion can be easily provided integrally with the spool shaft. In addition, 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 with the handle 54 provided on the reel 3 is described. However, the reel loading and unloading mechanism of the present invention is also suitable for loading and unloading the reel shaft from the open end of the reel shaft. Reel for fishing reel. For example, a single-bearing reel with a built-in drive mechanism can be applied to the reel mounting and dismounting mechanism of the present invention when the handle is provided on the opposite side of the reel of the reel body. In addition, the reel loading and unloading mechanism of the present invention is also applicable to the spinning reel.
