BACKGROUND
1. Field of the Invention
The present invention relates to a spinning reel, in particular, to a rotor of a spinning reel that delivers fishing line in the forward direction.
2. Background Information
A rotor pivotally coupled to a fishing line guide portion for winding fishing line on a spool is provided to a spinning reel. The rotor includes a coupling portion rotatably supported by the reel body via a pinion gear and first and second rotor arms provided to the coupling portion. The outside surface of the first rotor arm is covered with a cover member. A cylindrically shaped open portion is formed at the rear end portion of the coupling portion. There is a concern that the outside surface of the cover member provided to the open portion, the first rotor arm, and the second rotor arm may be scratched when the spinning reel is placed on the ground with the fishing pole attached. There is a well-known spinning reel that has a guard member for guarding the first and second rotor arms and the rear end portion of the coupling portion (refer to Japanese Laid Open Patent Publication No. 2005-095131 and Japanese Laid Open Patent Publication No. 2004-141039). The cover member in Japanese Laid Open Patent Publication No. 2005-095131 is made from metal and is disposed so as to protrude to the surface from between the open portion and the cover member provided to the rotor arms or the rear cover member that covers the open portion. The guard member in Japanese Laid Open Patent Publication No. 2004-141039 is an integrally formed member made from metal which guards and reinforces the first and second rotor arms. The guard member is disposed between the rear end portion of the coupling portion and the cover member as well as between the first and second rotor arms.
SUMMARY
In the conventional spinning reel, when the guard member is scratched and the guard member needs to be replaced, removing the rear cover member that covers the opening and detaching the rotor from the reel body is necessary. Therefore, replacing the guard member is difficult.
The object of the present invention is to protect the boundary between the rear end surface and the outside surface of the coupling portion while allowing for easy replacement of the guard member.
The spinning reel according to the first aspect of the present invention is a reel for delivering fishing line in a forward direction. The spinning reel includes a spinning reel body, a handle, a rotor, and a spool. The handle is rotatably supported by the reel body. The rotor is supported by the reel body to rotate around a longitudinal axis that is offset from an axis of rotation of the handle. The spool is supported by the reel body to move in a longitudinal direction of the longitudinal axis, and the spool is arranged to have the fishing line wound thereon by the rotor.
The rotor includes a rotor body, a first cover member, a first guard member, a second guard member, and a fishing line guide portion. The rotor body has a cylindrical coupling portion, a first rotor arm, and a second rotor arm. The cylindrical coupling portion is rotatably supported by the reel body. The first rotor arm extends forward from a rear end portion of the coupling portion. The first rotor arm is spaced apart from the coupling portion. The first rotor arm has a pair of first side portions. The second rotor arm extends forward from the rear end portion of the coupling portion. The second rotor arm is spaced apart from the coupling portion. The second rotor arm has a pair of second side portions. The first and second rotor arms are located on diametrically opposite sides of the coupling portion.
The first cover member is removably attached to the rotor body and covers a radially outer side of the first rotor arm. The first guard member is removably attached to the rotor body. The first guard member has a first guard portion that covers at least a portion of a boundary between an outside surface of the coupling portion and the rear end surface of the coupling portion. The second guard member is removably attached to the rotor body. The second guard member has a second guard portion that covers at least a portion of the boundary between the outside surface and the rear end surface of the coupling portion at a position that opposes the first guard portion. The fishing line guide portion is pivotally coupled to the extreme ends of the first rotor arm and the second rotor arm.

Also, the second guard portion of the second guard member covers at least a portion of the boundary between the outside surface and the rear end surface of the coupling portion at a position that opposes the first guard portion. Here, at least a portion of the boundary between the outside surface and the rear end surface of the coupling portion is protected by the two guard members, namely, the first guard member and the second guard member at the respectively different positions. Therefore, the first guard member and the second guard member can be detached separately without detaching the rotor from the reel body. As a result, the rear end surface and the outside surface of the coupling portion can be protected while allowing for easy replacement.
The spinning reel according to the second aspect of the present invention relates to the spinning reel according to the first aspect of the present invention, wherein the first guard portion and the second guard portion are disposed in the coupling portion between the first rotor arm and the second rotor arm. In this case, due to the first guard portion and the second guard portion being disposed in the coupling portion between the first rotor arm and the second rotor arm, the rear end portion of the coupling portion that may come into contact with the ground can reliably be protected. Also, integrally forming the section for protecting the first rotor arm and the second rotor arm is easy when protecting in combination both the first rotor arm and the second rotor arm.
The spinning reel according to the third aspect of the present invention relates to the spinning reel according to the second aspect of the present invention, wherein a third guard portion that covers at least a portion of a boundary between the first cover member and one of the first side portions of the first rotor arm.

Replacement Method of the First Guard Member and the Second Guard Member
When, for example, the first guard member 34 in a spinning reel 100 configured as described above is scratched, the two screw members 55a that are fastening the first cover member 32 are removed, and the first cover member 32 is detached from the first rotor arm 30b. Then, upon removing the two screw members 56a and 56b, which fasten the first guard member 34 to the rotor body 30, the first guard member 34 can be detached from the rotor body 30.
Also, the first guard member 34 and the second guard member 35 are made from a synthetic resin that does not have a coat, thereby allowing the color of the synthetic resin material to appear on the surface. Therefore, even if the members are scratched, the scratch will not be too conspicuous.
Features
The embodiment described above can be expressed as follows.
(A) The spinning reel 100 is a reel capable of delivering fishing line in the forward direction. The spinning reel 100 includes a reel body 2, a rotor 3, and a spool 4. A handle 1 is rotatably supported by the reel body 2. The rotor 3 is supported by the reel body 2 to rotate around the longitudinal axis X, the longitudinal axis X being offset from a location of the handle 1. The spool 4 is supported by the reel body 2 to move in the direction of the longitudinal axis and is wound with fishing line via the rotor 3.
The rotor 3 includes rotor body 30, a first cover member 32, a first guard member 34, a second guard member 35, and a bail arm 36. The rotor body 30 has a cylindrical coupling portion 30a, a first rotor arm 30b, and a second rotor arm 30c. The cylindrical coupling portion 30a is rotatably supported by the reel body 2. The first rotor arm 30b extends forward from the rear end portion of the coupling portion 30a and is spaced apart from the coupling portion 30a. The first rotor arm 30b has a pair of first side portions 30d and 30e. The second rotor arm 30c extends forward from a position that opposes the first rotor arm 30b at the rear end portion of the coupling portion 30a and is spaced apart from the coupling portion 30a. The second rotor arm 30c has a pair of second side portions 30f and 30g. 
The first cover member 32 is detachably provided to the rotor body 30 and covers the radially outer side of the first rotor arm 30b. The first guard member 34 is detachably provided to the rotor body 30 and has a first guard portion 34a. The first guard portion 34a covers at least one portion of the boundary between the outside surface of the coupling portion 30a and the rear end surface of the coupling portion 30a. The second guard member 35 is detachably provided to the rotor body 30 and has a second guard portion 35a. The second guard portion 35a covers at least one portion of the boundary between the outside surface of the coupling portion 30a and the rear end surface of the coupling portion 30a at a position that opposes the first guard portion 34a. The bail arm 36 is pivotally provided to the extreme ends of the first rotor arm 30b and the second rotor arm 30c. 
In this spinning reel 100, the first guard portion 34a of the first guard member 34 covers at least one portion of the boundary between the outside surface of the coupling portion 30a and the rear end surface of the coupling portion 30a. Also, the second guard portion 35a of the second guard member 35 covers at least one portion of the boundary between the outside surface of the coupling portion 30a and the rear end surface of the coupling portion 30a at a position that opposes the first guard portion 34a. Here, at least one portion of the boundary between the outside surface and the rear end surface of the coupling portion 30a is protected by the two guard members, namely, the first guard member 34 and the second guard member 35, at the respectively different positions. Therefore, the first guard member 34 and the second guard member 35 can be detached separately without detaching the rotor 3 from the reel body 2. As a result, the rear end surface and the outside surface of the coupling portion 30a can be protected while allowing for easy replacement.
(B) In the spinning reel 100, the first guard portion 34a and the second guard portion 35a are disposed at the coupling portion 30a between the first rotor arm 30b and the second rotor arm 30c. In this case, due to the first guard portion 34a and the second guard portion 35a being disposed at the coupling portion 30a between the first rotor arm 30b and the second rotor arm 30c, the rear end portion of the coupling portion 30a that may come into contact with the ground can be reliably protected. Also, integrally forming the section for protecting the first rotor arm 30b and the second rotor arm 30c is easy when protecting in combination both the first rotor arm 30b and the second rotor arm 30c. 
(C) In the spinning reel 100, the first guard member 34 is integrally formed with the first guard portion 34a and has, in addition, a third guard portion 34b that covers at least one portion of the boundary between the first cover member 32 and the first side portion 30d of the first rotor arm 30b. The second guard member 35 is integrally formed with the second guard portion 35a and has, in addition, a fourth guard portion 35b that covers at least one portion of the boundary between the first cover member 32 and the other first side portion 30e of the first rotor arm 30b. In this case, in addition to protecting the rear end surface and the outside surface of the coupling portion 30a, the boundary between the pair of side portions 30d and 30e of the first rotor arm 30b and the first cover member 32 can be protected.
(D) In the spinning reel 100, the first cover member 32 is fixed at least to the first rotor arm 30b with the screw member 55a. The first guard member 34 is fixed to the rotor body 30 by the screw member 56a at a connecting section that is located between the first guard portion 34a and the third guard portion 34b. The second guard member 35 is also fixed to the rotor body by the screw member 56a at a connecting section that is located between the second guard portion 35a and the fourth guard portion 35b. 
In this case, the first cover member 32 is fixed to the first rotor arm 30b with the screw member 55a. Also the first guard member 34 and the second guard member 35 are fixed to the rotor body 30 by the respective screw members 56a and 56b. Therefore, the first guard member 34 and the second guard member 35 can be detached from the rotor body 30 via the respective screw members 56a and 56b. 
(E) In the spinning reel 100, the third guard portion 34b is disposed between the first cover member 32 and the first rotor arm 30b and has a first holding portion 34f fixed to the first rotor arm 30b by the first cover member 32. The fourth guard portion 35b is disposed between the first cover member 32 and the first rotor arm 30b and has a second holding portion 35f fixed to the first rotor arm 30b by the first cover member 32.
In this case, when the first cover member 32 is fixed to the first rotor arm 30b, the first holding portion 34f and the second holding portion 35f are fixed to the first rotor arm 30b. Therefore, even if the first guard member 34 and the second guard member 35 are respectively fixed with a single screw member 56a, wobbling is not likely to occur in the third guard portion 34b and the fourth guard portion 35b. 
(F) In the spinning reel 100, the first holding portion 34f has a first engaging portion 34g that prevents displacement of the third guard portion 34b by engaging the inner surface of the first cover member 32. The first holding portion 34f also has a first positioning protrusion 34h that is provided separate from the first engaging portion 34g, with the first positioning protrusion 34h positioning the third guard portion 34b. The second holding portion 35f has a second engaging portion 35g that prevents displacement of the fourth guard portion 35b by engaging the inner surface of the first cover member 32. The second holding portion 35f also has a second positioning protrusion 35h that is provided separate from the second engaging portion 35g, the second positioning protrusion 35h positioning the fourth guard portion 35b. 
In this case, even if the first guard member 34 and the second guard member 35 are respectively fixed to the rotor body 30 with a single screw member 56a, displacement of the third guard portion 34b of the first guard member 34 can be prevented with the first engaging portion 34g, and displacement of the fourth guard portion 35b of the second guard member 35 can be prevented with the second engaging portion 35g. Also, the third guard portion 34b is positioned by the first positioning protrusion 34h, and the fourth guard portion 35b is positioned by the second positioning protrusion 35h. Therefore, the third guard portion 34b and the fourth guard portion 35b are not likely to be displaced.
(G) In the spinning reel 100, the first guard portion 34a and the third guard portion 34b of the first guard member 34 and the second guard portion 35a and the fourth guard portion 35b of the second guard member 35 are connected smoothly.
In this case, the third guard portion 34b disposed along the longitudinal direction and the first guard portion 34a disposed along the circumferential direction, as well as the fourth guard portion 35b disposed along the longitudinal direction and the second guard portion 35a disposed along the circumferential direction, are connected smoothly. Therefore, the fishing line is not likely to get caught at the connecting section(s).
(H) In the spinning reel 100, the rotor 3 has, in addition, a second cover member 33 that covers the radial outer side of the second rotor arm 30c. The first side portion 30d of the first rotor arm 30b is disposed upstream of the other first side portion 30e with respect to the fishing line winding direction A of the rotor 3. The first guard member 34 covers at least one portion of the boundary between the second side portion 30f of the second rotor arm 30c and the second cover member 33 and has a fifth guard portion 34c integrally formed with the first guard portion 34a. The second guard member 35 covers at least one portion of the boundary between the other second side portion 30g of the second rotor arm 30c and the second cover member 33 and has a sixth guard portion 35c integrally formed with the second guard portion 35a. The second side portion 30f of the second rotor arm 30c is disposed downstream of the other second side portion 30g with respect to the fishing line winding direction A.
In this case, the boundary between the second side portion 30f of the second rotor arm 30c and the second cover member 33 is covered with the first guard member 34, and the boundary between the other second side portion 30g of the second rotor arm 30c and the second cover member 33 is covered with the second guard member 35. Therefore, it is possible to protect the boundary between the pair of second side portions 30f and 30g of the second rotor arm 30c and the second cover member 33 in addition to protecting the boundary between the rear end surface and the outside surface of the coupling portion 30a and the boundary between the pair of first side portions 30d and 30e of the first rotor arm 30b and the first cover member 32.
(I) In the spinning reel 100, the second cover member 33 is fixed at least to the second rotor arm 30c with the screw member 55b. The first guard member 34 is fixed to the rotor body 30 at the connecting section of the first guard portion 34a and the fifth guard portion 34c, and the second guard member 35 is fixed to the rotor body at the connecting section of the second guard portion 35a and the sixth guard portion 35c, respectively, by the screw member 56b. 
In this case, the second cover member 33 is fixed to the rotor with the screw member 55b, and the first guard member 34 and the second guard member 35 are fixed to the rotor body 30 with the respective screw member 56a and screw member 56b. Therefore, the first guard member 34 and the second guard member 35 can be detached from the rotor body 30 via the screw members 56a and 56b, respectively.
(J) In the spinning reel 100, the fifth guard portion 34c is disposed between the second cover member 33 and the second rotor arm 30c and has a third holding portion 34i fixed to the second rotor arm 30c by the second cover member 33. The sixth guard portion 35c is disposed between the second cover member 33 and the second rotor arm 30c and has a fourth holding portion 35i fixed to the second rotor arm 30c by the second cover member 33.
In this case, when the second cover member 33 is fixed to the second rotor arm 30c, the third holding portion 34i and the fourth holding portion 35i are fixed to the second rotor arm 30c. Therefore, even if the respective connecting section of the first guard member and the second guard member are fixed with the respective screw member 56a and screw member 56b, wobbling is not likely to occur in the fifth guard portion 34c and the sixth guard portion 35c. 
(K) In the spinning reel 100, the third holding portion 34i has a third engaging portion 34j that prevents displacement of the fifth guard portion 34c by engaging the inner surface of the second cover member 33. The third holding portion 34i also has a second positioning protrusion 34k that is provided separate from the third engaging portion 34j, with the second positioning protrusion 34k positioning the fifth guard portion 34c. The fourth holding portion 35i has a fourth engaging portion 35j that prevents displacement of the sixth guard portion 35c by engaging the inner surface of the second cover member 33. The fourth holding portion 35i also has a fourth positioning protrusion 35k that is provided separate from the fourth engaging portion 35j, the fourth positioning protrusion 35k positioning the sixth guard portion 35c. 
In this case, even if the first guard member 34 and the second guard member 35 are respectively fixed to the rotor body 30 by the screw member 56a and the screw member 56b at the respective connecting sections, displacement of the fifth guard portion 34c of the first guard member 34 and the sixth guard portion 35c of the second guard member 35 can be prevented by the third engaging portion 34j and the fourth engaging portion 35j, respectively; moreover, the positioning thereof is carried out by the third positioning protrusion 34k and the fourth positioning protrusion 35k. Therefore, even if a fifth guard portion 34c is provided to the first guard member 34 and a sixth guard portion 35c to the second guard member 35, displacement of the fifth guard portion 34c and the sixth guard portion 35c is not likely to occur.
(L) In the spinning reel 100, the first guard portion 34a and the fifth guard portion 34c of the first guard member 34 and the second guard portion 35a and the sixth guard portion 35c of the second guard member 35 are connected smoothly.
In this case, the fifth guard portion 34c disposed along the longitudinal direction and the first guard portion 34a disposed along the circumferential direction, as well as the sixth guard portion 35c disposed along the longitudinal direction and the second guard portion 35a disposed along the circumferential direction, are connected smoothly. Therefore, the fishing line is not likely to get caught at the connecting section(s).
(M) In the spinning reel 100, the first guard member 34 and the second guard member 35 are made from a synthetic resin, and the synthetic resin material is exposed to the outside surface. In this case, due to the first guard member 34 and the second guard member 35 being made from a synthetic resin, reduction in the weight can be achieved even if a guard member that is softer and more easily scratched than that made from metal is installed. Also, the synthetic resin material is exposed to the outside surface, namely, a coat is not formed according to plating, coating, or the like. Therefore, the coat does not peel off, and only the material itself is scratched. As a result, even if the first guard member 34 and the second guard member 35 are scratched, the scratch will not be too conspicuous.
Other Embodiments
One embodiment of the present invention was described above. However, the present invention is not limited to the embodiment described above, and various changes are possible without deviating from the essence of the invention. In particular, the many embodiments and modifications described in the specification can be optionally combined as needed.
(a) In the embodiment described above, a rear cover member is not disposed at the rear surfaces of the first guard member 34 and the second guard member 35. However, the present invention is not limited to this mode. For example, it is possible to provide a first rear cover member 134 and a second rear cover member 135 that respectively connect the two end portions of the first guard portion 34a of the first guard member 34 and the two end portions of the second guard portion 35a of the second guard member 35, as illustrated in FIG. 7. In this case, detachment of the cover members is made easy by providing the first rear cover member 134 and the second rear cover member 135 separate from the first guard member 34 and the second guard member 35, as illustrated in FIG. 7. In FIG. 7, the first rear cover member 134 is fixed to the rotor body 30 together with the first guard member 34 and the second guard member 35 by the screw member 56a. The second rear cover member 135 is fixed to the rotor body 30 together with the first guard member 34 and the second guard member 35 by the screw member 56b.

(b) In the embodiment described above, the first and second cover members 32 and 33 were provided to both the first and second rotor arms 30b and 30c. However, the cover member can be provided to only one of the rotor arms. In this case, it is possible in a rotor arm that does not have a cover member, for example, to provide a mounting concave portion to the pair of side parts of the rotor arm. It is also possible to not provide the fifth guard portion and the sixth guard portion.
(c) In the embodiment described above, a third guard portion 34b and a fifth guard portion 34c were provided to the first guard member 34, and a fourth guard portion 35b and a sixth guard portion 35c were provided to the second guard member 35. However, these portions need not be provided. Also, the third, fourth, fifth, and sixth guard members can respectively be provided to be independent from the first guard member and the second guard member. It is also possible to integrally form the third guard portion and the fourth guard portion, as well as the fifth guard portion and the sixth guard portion.
(d) In the other embodiment (a), the first rear cover member and the second rear cover member were provided as separate members. However, these members can be integrally formed with an annular shape. In this case, the screw that is fastening the rear cover member and the guard member with the rotor left attached to the reel body is removed, the rear cover member is slid towards the rear, and the guard member is removed.
