Therefore, it is an object of the present invention to provide an engaging structure of a reel sheet capable of obtaining a good appearance.

The present invention has been made to solve the above problems, and the engagement structure of the reel sheet according to the present invention is an engagement structure in a tubular reel sheet for a fishing rod, and is attached to the rod body of the fishing rod. A tubular reel seat body having a male screw portion, and a moving cylinder mounted on the outside of the reel seat body, which can move along the center line direction with respect to the reel seat body and cannot rotate relative to each other. It is equipped with a nut that is screwed into the male screw part of the reel seat body to move the moving cylinder along the center line direction. A portion is formed, and at the end of the other member, a plurality of projecting pieces protruding toward the one member in the center line direction are formed at intervals in the circumferential direction, and a plurality of projecting pieces are formed on the outer surface of the plurality of projecting pieces. Is formed with an engaging groove that engages with the engaging convex portion and extends in the circumferential direction, respectively. It has a second side surface located on the end side and a bottom surface connecting both side surfaces, and the engaging protrusion is the first side surface located on the other member side and the side opposite to the first side surface. It has a second side surface located at, and a protruding end surface connecting both side surfaces, a boundary portion between the second side surface and the bottom surface in the engaging groove, and a first side surface and the protruding end surface in the engaging convex portion. It is characterized in that an inclined surface is formed at each of the boundary portions of the above.

In the engaging structure having the above configuration, an inclined surface is formed in each of the engaging groove and the engaging convex portion, so that when the nut is tightened, the inclined surface of the engaging groove and the engaging convex surface are formed. The inclined surfaces of the portions can come into contact with each other. When the inclined surface of the engaging groove and the inclined surface of the engaging convex portion come into contact with each other, a centering action acts between the inclined surface of the engaging groove and the inclined surface of the engaging convex portion, and the nut moves with the center line of the nut. Positional deviation from the center line of the cylinder is suppressed. In addition, when the nut is tightened, the nut does not easily shift in the radial direction with respect to the moving cylinder, so the rotation operation of the nut near the completion of tightening the nut is stable and the operation feeling is excellent, and a stable tightening force is provided. It is also possible to obtain. Further, since the engaging grooves are formed on the outer surfaces of the plurality of projecting pieces and the projecting pieces are separated from each other in the circumferential direction, the engaging grooves and the engaging convex portions are difficult to stick to each other, and the nut can be used. The rotation can be started smoothly. Further, since the plurality of projecting pieces can be slightly bent inward in the radial direction near the completion of tightening of the nut, a firm tightening feeling can be obtained.

In particular, the inclined surface of the engaging groove is larger than the first side surface of the engaging groove, and the inclined surface of the engaging convex portion is preferably larger than the second side surface of the engaging convex portion, and stable centering is performed. You can get the effect.

Further, it is preferable that the engaging groove is formed at the base end portion of the protruding piece portion, and the second side surface of the engaging groove portion constitutes a part of the end surface of the other member, and the engaging groove is formed. It is easy to secure the strength of the protruding piece.

Further, a plurality of guide grooves extending in the center line direction are formed on the outer peripheral surface of the reel seat body at intervals in the circumferential direction, and a moving convex portion engaging with the guide groove is formed on the inner peripheral surface of the moving cylinder. A plurality of protrusions for movement are formed at intervals in the circumferential direction, and each of the plurality of protrusions for movement is extended from the end of the moving cylinder in the direction of the center line to form a protrusion, and the protrusion is convex for movement. It is preferable that it constitutes a part of the portion. In the case of the configuration in which the projecting piece portion and the moving convex portion are integrally formed in this way, it becomes easy to secure a large thickness of the projecting piece portion, that is, a large radial dimension, and the strength of the projecting piece portion is ensured. It will be easier to do. Further, when the nut is tightened, the projecting piece portion of the moving cylinder slightly bends inward in the radial direction, and the inner surface of the projecting piece portion can be pressed against the bottom surface of the guide groove. When the inner surface of the projecting piece is pressed against the bottom surface of the guide groove, the position of the moving cylinder with respect to the reel seat body is stabilized, and the moving cylinder can be firmly fixed at a predetermined position of the reel seat body.

In particular, a lightening recess is formed in the central portion in the width direction of the end portion of the moving convex portion on the opposite side of the projecting piece portion, and the end portion of the moving convex portion on the opposite side of the projecting piece portion is bifurcated. It is preferable that the convex portion is formed in a shape, and the width of the convex portion for movement can be secured, and the shape of the convex portion for movement is stable when formed from synthetic resin by injection molding.

As described above, since the centering function is exerted by the inclined surface of the engaging groove and the inclined surface of the engaging convex portion, the coaxiality between the outer peripheral surface of the end portion of the nut and the outer peripheral surface of the end portion of the moving cylinder is increased. It can be improved and a good appearance can be obtained. Further, since the engaging groove is formed in the plurality of projecting pieces, the engaging groove is fixed between the engaging groove and the engaging convex portion as compared with the annular configuration in which the engaging groove is continuous over the entire circumference. Is less likely to occur, and smooth rotation of the nut can be obtained. Further, since the protruding piece portion can be slightly bent inward, a stable tightening force can be easily obtained and the nut is excellent in operability.

By removing the replacement member 8 from the fixing member 7, the lateral overhanging portion 16, the support wall portion 17, and the grip portion 18 are collectively removed from the fixing member 7. The replacement member 8 may be configured to include a trigger.

<Installation and removal of replacement member 8>
As shown in FIG. 8, the replacement member 8 can be attached to and detached from the fixing member 7 in a state where the holding nut 5 is loosened and retracted to the rear side. The work of attaching and detaching the replacement member 8 can be performed with the reel sheet attached to the fishing rod. With the fixing member 7 attached to the rod body 100, the replacement member 8 can be attached or detached. Therefore, if another type of replacement member 8 is prepared, only the replacement member 8 can be replaced while the reel sheet is attached to the fishing rod. For example, the replacement member 8 having the support wall portion 17 formed on the left side can be replaced with the replacement member 8 having the support wall portion 17 formed on the right side. Therefore, by replacing only the replacement member 8, it is possible to replace the double-screw reel having the handle 105 on the right side with the double-screw reel having the handle on the left side. Further, the support wall portion 17 can be easily replaced with a replacement member 8 having various specifications such as the shape and size of the support wall portion 17, the overhanging amount of the side overhanging portion 16, the position and size of the grip portion 18, and the presence or absence thereof. Further, the replacement member 8 can be easily replaced with another replacement member 8 having a different material, color, design, or the like. Therefore, the angler can freely customize and enjoy the reel seat according to the taste of the angler, the type of the double-screw reel, the target fish, the situation, and the like.

Since such replacement of the replacement member 8 can be performed with the reel seat attached to the fishing rod, the angler can easily replace the replacement member 8. For example, the replacement member 8 can be easily replaced even at a fishing site, and the replacement member 8 can be replaced even when the double-screw reel is attached to the fishing rod. In particular, since the holding nut 5 can be replaced by tightening and loosening operations, the replacement work is extremely simple and can be replaced quickly. Even if the replacement member 8 is removed, the reel leg mounting portion 11, the fixed hood portion 12, the movable hood 3, and the hood nut 2 remain on the reel seat as they are. It is also possible to attach a double-screw reel for fishing.

In the reel seat configured as described above, when the holding nut 5 is tightened to the front side, the inclined surface 50d of the engaging convex portion 50 comes into contact with the inclined surface 41d of the engagement groove 41. A centering action acts between the inclined surface 41d of the engaging groove 41 and the inclined surface 50d of the engaging convex portion 50. That is, the misalignment between the center line of the holding nut 5 and the center line of the extension sleeve 4 is suppressed. Therefore, only a predetermined portion of the entire circumference of the outer peripheral surface of the front end portion of the holding nut 5 protrudes radially outward from the outer peripheral surface of the rear end portion of the extension sleeve 4, or conversely, extends. It is prevented from being dented by being locally displaced inward in the radial direction with respect to the outer peripheral surface of the rear end of the sleeve 4, and the outer peripheral surface of the front end of the holding nut 5 and the outer peripheral surface of the rear end of the extension sleeve 4. Is kept evenly aligned in the radial direction over the entire circumference. Therefore, a good appearance can be obtained. Since the holding nut 5 is a member operated by an angler, it is easily noticeable. Therefore, the effect of improving the coaxiality between the outer peripheral surface of the front end portion of the holding nut 5 and the outer peripheral surface of the rear end portion of the extension sleeve 4 is great. In particular, in the present embodiment, the outer peripheral surface of the front end portion of the holding nut 5 and the outer peripheral surface of the rear end portion of the extension sleeve 4 have substantially the same diameter and are substantially flush with each other. If the outer peripheral surface of the portion is displaced in the radial direction with respect to the outer peripheral surface of the rear end portion of the extension sleeve 4, it is easily noticeable, and the effect of the centering action is large.

Further, since the holding nut 5 is less likely to be displaced in the radial direction with respect to the extension sleeve 4 near the completion of tightening the holding nut 5, the rotation operation of the holding nut 5 is stable near the completion of tightening of the holding nut 5. , Excellent operation feeling. Moreover, a stable tightening force can be obtained. Further, since the engaging groove 41 is not annular but is formed on the outer surface of the plurality of projecting pieces 40, the engaging groove 41 and the engaging convex portion 50 are difficult to be fixed to each other. Especially in sea fishing, the occurrence of salt stains can be suppressed. Therefore, when the rotation operation of the holding nut 5 is started, the holding nut 5 starts to rotate smoothly. Further, since the plurality of projecting pieces 40 are slightly bent inward in the radial direction near the completion of tightening of the holding nut 5, a firm tightening feeling can be obtained. Then, since the inner surface of each protruding piece portion 40 is pressed against the bottom surface 41c of the guide groove 30 of the reel seat body 1, the position of the extension sleeve 4 with respect to the reel seat body 1 is also stable, and the extension sleeve 4 is firmly placed at a predetermined position. It can be fixed and the mounting state of the replacement member 8 is stable. Further, since the inclined surface 41d of the engaging groove 41 is larger than the first side surface 41a of the engaging groove 41, and the inclined surface 50d of the engaging convex portion 50 is larger than the second side surface 50b of the engaging convex portion 50. , Stable centering action can be obtained, and stable tightening force can also be obtained.

Since the engaging groove 41 is formed at the base end portion of the projecting piece portion 40, and the second side surface 41b of the engaging groove 41 forms a part of the rear end surface 4a of the extension sleeve 4, the projecting piece It is easy to secure the strength of the portion 40, and it is possible to prevent the projecting piece portion 40 from being damaged. Further, since the projecting piece portion 40 and the moving convex portion 31 are integrally formed, the thickness of the projecting piece portion 40 can be easily secured, and the strength of the projecting piece portion 40 can be easily secured. Further, since the projecting piece portion 40 constitutes the rear portion of the moving convex portion 31, the length of the moving convex portion 31 in the front-rear direction is extended, and a long overall length can be secured. Therefore, the moving convex portion 31 can slide smoothly back and forth along the guide groove 30, and the extension sleeve 4 can move smoothly back and forth. On the other hand, since the lightening concave portion 32 is formed in the front portion of the moving convex portion 31 and the front portion of the moving convex portion 31 is bifurcated, the width of the moving convex portion 31 is secured. It is possible to suppress excessive uneven thickness at the rear end portion of the extension sleeve 4, and the shape of the moving convex portion 31 is stabilized.

A similar centering mechanism may be adopted for the engagement structure between the hood nut 2 and the movable hood 3. FIG. 9 shows an enlarged view of the engagement structure between the rear end portion of the hood nut 2 and the front end portion of the movable hood 3. A plurality of projecting piece portions 60 are provided at the front end portion of the movable hood 3. The engaging groove 61 is formed on the outer surface of the projecting piece portion 60. The engaging groove 61 includes a first side surface 61a located on the front end side of the projecting piece 60 and a second side surface 61b located on the base end side of the projecting piece 60 and located on the rear side. It has a bottom surface 61c that connects both side surfaces 61a and 61b, and an inclined surface 61d is formed at a boundary between the second side surface 61b and the bottom surface 61c. The engaging protrusion 70 of the hood nut 2 is annular, and has an annular first side surface 70a located on the rear side, an annular second side surface 70b located on the front side, and a first side surface 70a and a first surface. It has an annular tip surface 50c connecting the two side surfaces 70b, and an inclined surface 70d is formed at the boundary between the first side surface 70a and the tip surface 70c. Then, when the hood nut 2 is moved to the rear side and the movable hood 3 is pushed to the rear side, the inclined surface 70d of the engaging convex portion 70 of the hood nut 2 becomes the inclined surface 61d of the engaging groove 61 of the movable hood 3. Contact with. The center line of the hood nut 2 substantially coincides with the center line of the movable hood 3, and the hood nut 2 is centered.

The holding nut 5 may be provided with a protruding piece portion and an engaging groove, and the extension sleeve 4 may be provided with an engaging convex portion. Similarly, the hood nut 2 may be provided with a protruding piece portion and an engaging groove, and the movable hood 3 may be provided with an engaging convex portion.
