Description

  The present invention relates to a fishing spinning reel, and more particularly to a fishing spinning reel characterized by a waterproof mechanism for a handle shaft.

  Generally, a fishing spinning reel includes a reel body and a spool that is attached to the reel body and on which a fishing line is wound. A handle that is operated to wind the fishing line on the spool is rotatably supported on the reel body. And this handle | steering-wheel usually has a knob part gripped by a fisherman, a handle shaft connected to a drive gear (drive shaft having a drive gear) that is a part of a take-up drive mechanism of the reel body, and this handle shaft. And a handle body connecting the knob.

  Conventionally, this type of fishing spinning reel has a screw hole extending in the axial direction at the end of the handle shaft, and the drive is performed on one side (for example, the right side) of the drive shaft provided in the reel body. A handle is attached to the drive shaft by inserting and fitting the shaft into the screw hole. In such a configuration, the drive shaft can be inserted and fitted into the screw hole on the other side (for example, the left side) of the drive shaft. It can be rearranged (replaced) with. In this case, on the side of the drive shaft to which the handle is not attached, a cap for closing the inside of the reel body from the outside is attached to the reel body.

  By the way, in such a structure in which the handle can be rearranged, it is necessary to waterproof the handle shaft. As a waterproofing technique for the handle shaft of the spinning reel, for example, techniques disclosed in Patent Document 1 and Patent Document 2 are known. That is, in Patent Document 1, a seal member (packing ring) is disposed outside a bearing (ball bearing) that rotatably supports a drive shaft on both the left and right sides of a reel body (housing). The outer side in the radial direction is waterproofed by being crushed by the outer ring of the bearing, and the inner side in the radial direction of the seal member is waterproofed by sliding contact with the drive shaft (handle shaft). On the other hand, in Patent Document 2, a seal member is disposed on the handle shaft, and the inner side in the radial direction of the seal member is waterproofed by being press-fitted into the handle shaft, and the outer side in the radial direction of the seal member is on the reel body side. Waterproofing is achieved by sliding contact.

  However, in Patent Document 1, the seal member always slides on both the left and right sides of the reel body (housing), that is, on both sides of the drive shaft, regardless of whether the handle is assembled to the left or right. There is a problem that the friction generated between the handle and the handle shaft) increases, and therefore the handle rotation operation becomes heavy.

  On the other hand, in Patent Document 2, since the seal member is disposed on the handle shaft, regardless of the position where the handle is assembled, the sliding position of the seal member is either one side of the reel body (the left or right side on the side where the handle is assembled). However, since the sliding portion of the seal member is on the radially outer side of the seal member, the sliding radius becomes larger than that in the case of sliding radially inward as in Patent Document 1. For this reason, the friction generated between the seal member and the reel body side is increased, and therefore the rotation operation of the handle becomes heavy.

  Further, in a structure in which the handle can be recombined, when combining the techniques of the two patent documents, that is, when the seal member is slid only on one side of the reel body and radially inward, the side on which the handle is attached In some cases, it is necessary to separately provide a seal member having a different form on each of the sides where the handle is not attached, and to change the seal member on the left and right when the handle is rearranged. In such a case, not only the replacement work takes time, but also problems such as loss or forgetting of components such as the seal member occur during the replacement work, and it becomes difficult to replace the handle at the fishing spot.

  Further, in the above two patent documents, even when the handle is rearranged on the left and right, the seal member is always in sliding contact with the mating member, so that the seal member is heavily consumed.

  The present invention has been made paying attention to the above circumstances, and the purpose of the present invention is to reduce the rotation of the handle, minimize wear of the seal member, and minimize the wear of the seal member. An object of the present invention is to provide a fishing spinning reel having a sealing structure that does not require replacement.

  In order to solve the above-mentioned problem, the invention according to claim 1 is configured to support a spool around which a fishing line is wound and to be provided on the reel body, and to wind the fishing line around the spool. A drive shaft connected to the take-up drive mechanism and a handle having a handle shaft that is detachably fitted to the drive shaft, and the handle can be attached to the left and right sides of the reel body by attaching / detaching the handle shaft to / from the drive shaft. A fishing spinning reel, which is attached to the reel body in a sealed state on both the left and right sides of the reel body, and includes left and right seal members for sliding contact with the handle shaft on the radially inner side thereof, The sliding contact portions on the radially inner side of the left and right seal members are in sliding contact with the handle shaft only when the handle shaft is attached to the drive shaft. Characterized in that it is formed.

  According to the first aspect of the present invention, the sliding contact portion on the radially inner side of the seal member is in sliding contact with the handle shaft, and therefore the sliding radius is smaller than that in the sliding contact on the radially outer side. Further, the seal member is formed so as to be in sliding contact with the handle shaft only when the handle shaft is attached to the drive shaft. Therefore, only the seal member on the side where the handle is attached slides with the handle shaft at the sliding contact portion. In order to make contact (because the seal member is in sliding contact with only one side of the reel body), the rotation operation of the handle can be made lighter than in the past (particularly, Patent Documents 1 and 2). In the above configuration, since only the seal member on the side where the handle is attached is in sliding contact with the handle shaft at the sliding contact portion, that is, when the handle is rearranged on the left and right, the sealing member involved in the sliding contact is also switched. Only the member is not always in sliding contact, and the consumption of the seal member can be minimized. Further, in the above configuration, since the seal members are provided on the left and right respectively corresponding to the left and right rearrangement of the handle, it is not necessary to replace the seal member when the handle is rearranged. Therefore, it is easy to rearrange the left and right handles, and problems such as loss or forgetting to attach components such as a seal member during the rearrangement work do not occur.

  According to a second aspect of the present invention, in the first aspect of the present invention, each of the seal members is detachably attached to the reel body.

  According to the second aspect of the invention, the same effect as that of the first aspect of the invention can be obtained, and the seal member is detachable from the reel body, so that the worn seal member can be replaced. It becomes easy.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the seal member faces the direction substantially perpendicular to the radial direction and is in a sealed state with the blocking member. It has the side part which can contact, It is characterized by the above-mentioned.

  According to the third aspect of the invention, the same effect as that of the first or second aspect of the invention can be obtained, and the seal member faces in a direction substantially orthogonal to the radial direction. Since it has a side part that can be brought into contact with the closing member in a sealed state, a sealing member such as a sliding contact part that has been deformed in a direction different from the radial direction due to long-term use as the handle is rearranged. This part can be corrected (in the normal radial direction) by sealing contact between the side surface portion and the closing member.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the sealing member is configured such that the outer surface portion that can come into contact with the closing member in a sealed state is in the sliding contact. It has in the radial direction outer side which opposes a part in radial direction, It is characterized by the above-mentioned.

  According to the fourth aspect of the present invention, the same effect as that of any one of the first to third aspects of the present invention can be obtained, and the sealing member is in a sealed state with the closing member. Since the outer surface portion that can be contacted is provided on the radially outer side facing the sliding contact portion in the radial direction, the load acting on the seal member is dispersed in the radial direction (the seal pressure is divided between the radially outer side and the inner side). And the durability of the seal member is improved.

  According to a fifth aspect of the present invention, there is provided a reel body for supporting a spool around which a fishing line is wound and a winding drive mechanism provided on the reel body and configured to wind the fishing line on the spool. A drive shaft, and a handle having a handle shaft that is detachably fitted to the drive shaft, and the handle can be replaced on the left and right of the reel body by attaching / detaching the handle shaft to / from the drive shaft. A spinning reel for fishing, in which a closing member for closing the opening is detachably attached to a handle attachment opening on the side of the reel body that is not provided, and is sealed against the reel body on both the left and right sides of the reel body A right side seal member and a left side seal member that are attached in a state and are in sliding contact with the handle shaft on the radially inner side, the handle being the reel When attached to the right side of the body, the sliding contact portion on the radially inner side of the right seal member is in sliding contact with the handle shaft, and the left seal member is in a sealed state with the closing member without sliding contact with the handle shaft. When the handle is attached to the left side of the reel body, the sliding contact portion on the radially inner side of the left seal member is in sliding contact with the handle shaft, and the right seal member is in sliding contact with the handle shaft. The sealing member is in contact with the closing member in a sealed state.

  According to the fifth aspect of the present invention, the sliding contact portion on the radially inner side of the seal member is in sliding contact with the handle shaft, and therefore the sliding radius is smaller than that in the sliding contact on the radially outer side. Further, since only the seal member on the side on which the handle is attached is in sliding contact with the handle shaft at the sliding contact portion (because the sealing member is in sliding contact with only one side of the reel body), the rotation operation of the handle is conventionally performed (in particular, Patent Document 1, It can be made lighter than 2). In the above configuration, since only the seal member on the side where the handle is attached is in sliding contact with the handle shaft at the sliding contact portion, that is, when the handle is rearranged on the left and right, the sealing member involved in the sliding contact is also switched. Only the member is not always in sliding contact, and the consumption of the seal member can be minimized. Further, in the above configuration, since the seal members are provided on the left and right respectively corresponding to the left and right rearrangement of the handle, it is not necessary to replace the seal member when the handle is rearranged. Therefore, it is easy to rearrange the left and right handles, and problems such as loss or forgetting to attach components such as a seal member during the rearrangement work do not occur.

According to the present invention, it is possible to provide a fishing spinning reel having a seal structure in which the rotation operation of the handle can be lightened, consumption of the seal member can be minimized, and the replacement of the seal member is not required when the handle is replaced. .

The end of the shaft 6 is closed by attaching a cap (blocking member) 8 to a mounting opening 60 a (or 60 b) formed corresponding to the reel body 1. That is, the handle 10 can be mounted on either the left or right side of the reel body 1 by the handle mounting structure (the handle 10 can be replaced on the left or right side of the reel body 1 by attaching / detaching the handle shaft 12 to / from the drive shaft 6). ).

  As shown in FIG. 2 and FIG. 3, the handle 10 in this embodiment includes a handle shaft 12 coupled to the drive shaft 6 to rotationally drive the drive gear 7 that is a part of the winding drive mechanism 5, and the handle shaft 12. A handle body 13 having a handle shaft 12 and a knob 15 attached to the handle body 13 and gripped by a fisherman are provided. The handle main body 13 is configured to rotate integrally with the handle shaft 12, and protrudes outward from the reel main body 1 along the handle axial direction. The handle stand 13 a is radially outward at the protruding end of the handle stand 13 a. The knob 13 is provided at the tip of the arm 13b so as to be rotatable. The arm 13b may be configured to be foldable with respect to the handle stand 13a by a known folding mechanism.

  The handle shaft 12 is formed in a cylindrical shape, and a large-diameter female screw portion 12a and a small-diameter female screw portion 12b are sequentially formed from the opening end portion on the inner peripheral surface of the inner hole. On the other hand, the drive shaft 6 to which the handle shaft 12 is detachably attached has a small-diameter male screw portion 39 that can be screwed into the small-diameter female screw portion 12b on the outer peripheral surface of the right-side small-diameter end portion 6b. A large-diameter male screw portion 19 that can be screwed with the screw portion 12a is formed on the outer peripheral surface of the left-side large-diameter end portion 6a.

  Further, mounting flanges 1a and 1b for detachably mounting the cap 8 are provided on both the left and right sides of the reel body 1, and male screws 32a and 32b are formed on the outer peripheral surfaces of the mounting flanges 1a and 1b. Has been. The mounting flanges 1a and 1b are provided with the above-described mounting openings 60a and 60b for mounting the handle 10. Further, at the tips of the mounting flanges 1a and 1b, there are provided mounting portions 30a and 30b for detachably mounting seal members 20 and 22 described later in a sealed state.

  Further, the cap 8 for closing the mounting openings 60a and 60b is formed with an internal thread 8b that can be screwed into the external threads 32a and 32b of the mounting flanges 1a and 1b on the inner peripheral surface near the opening end. Further, the cap 8 has a cylindrical portion 8 a extending from the inner bottom surface, and the outer diameter of the cylindrical portion 8 a is set to be substantially the same as the outer diameter of the handle shaft 12.

  A seal member that is detachably attached to the attachment portions 30a and 30b of the reel body 1 includes a right seal member 22 and a left seal member 20, and seals between the reel body 1 and the handle shaft 12. . Specifically, each of the seal members 20 and 22 includes, for example, radially outer mounting portions 20b and 22b that are locked in a sealed state in, for example, recessed grooves on the outer peripheral surfaces of the mounting portions 30a and 30b of the reel body 1, and a handle shaft. 12 having a radially inner slidable contact portion 20a, 22a slidably contacting the outer peripheral surface of the rim 12, and a substantially ring-shaped cross section extending from the mounting portions 20b, 22b toward the slidable contact portions 20a, 22a. It has a shape. Further, the sliding contact portions 20a and 22b on the radially inner sides of the left and right seal members 20 and 22 are provided when the handle shaft 12 is attached to the drive shaft 6 (particularly in the present embodiment, with respect to the drive shaft 6). Only when the handle shaft 12 is attached) and is formed so as to be in sliding contact with the outer peripheral surface of the handle shaft 12. Specifically, the inner diameter of each seal member 20, 22 (the inner diameter of the sliding contact portions 20 a, 22 a) is set to be substantially the same as the outer diameter of the handle shaft 12, while the left large-diameter end of the drive shaft 6. The outer diameter of 6a is set smaller than the inner diameters of the seal members 20 and 22 (inner diameters of the sliding contact portions 20a and 22a).

  Therefore, in the above configuration, as shown in the drawing, the small-diameter female screw portion 12b of the handle shaft 12 is screwed into the small-diameter male screw portion 39 of the right small-diameter end portion 6b of the drive shaft 6 so that the handle 10 is moved to the right side of the reel body 1. When the female screw 8b of the cap 8 is screwed into the male screw 32a of the left mounting flange 1a of the reel main body 1 to close the left mounting opening 60a, the sliding contact portion 22a on the radially inner side of the right seal member 22 is closed. Is in sliding contact with the handle shaft 12, and the left seal member 22 is in contact with the cylindrical portion 8a of the cap 8 in a sealed state without sliding contact with the handle shaft 12 and the drive shaft 6, and between the reel body 1 and the cap 8. Seal, thereby sealing the mounting opening 60a. On the other hand, although not shown, the handle 10 is attached to the left side of the reel body 1 by screwing the small diameter female screw portion 12b of the handle shaft 12 into the large diameter male screw portion 19 of the left large diameter end portion 6a of the drive shaft 6, and the reel When the female screw 8b of the cap 8 is screwed into the male screw 32a of the right mounting flange 1a of the main body 1 to close the right mounting opening 60b, the radially inner sliding contact portion 20a of the left seal member 20 becomes the handle shaft 12. The right seal member 22 seals between the reel body 1 and the cap 8 by contacting the cylindrical portion 8a of the cap 8 in a sealed state without sliding contact with the handle shaft 12 and the drive shaft 6. Thus, the mounting opening 60b is sealed.

  As described above, according to the present embodiment, the sliding contact portions 20a and 22a on the radially inner side of the seal members 20 and 22 are in sliding contact with the handle shaft, and therefore the sliding contact is performed on the radially outer side. The seal member 20 and 22 are formed so as to be in sliding contact with the handle shaft 12 only when the handle shaft 12 is attached to the drive shaft 6. Since only the seal member 20 (or 22) on the side to which is attached is slidably contacted with the handle shaft 12 at the slidable contact portion 20a (or 22a) (since the seal members 20 and 22 are slidably contacted only on one side of the reel body 1), the handle 10 rotation operations can be made lighter than in the past (particularly, Patent Documents 1 and 2). In the configuration of the present embodiment, only the seal member 20 (or 22) on the side to which the handle 10 is attached is in sliding contact with the handle shaft 12 at the sliding contact portion 20a (or 22a), that is, the handle 10 is rearranged left and right. Since the sealing member involved in the sliding contact is also switched, only one sealing member is not always in sliding contact, and wear of the sealing members 20 and 22 can be minimized. Furthermore, in the configuration of the present embodiment, since the seal members 20 and 22 are provided on the left and right respectively corresponding to the left and right rearrangement of the handle 10, it is not necessary to replace the seal members 20 and 22 when the handle 10 is rearranged. . Therefore, the left and right of the handle 10 can be easily rearranged, and problems such as the loss or forgetting to attach components such as the seal members 20 and 22 during the rearrangement work do not occur. Further, in the present embodiment, since the seal members 20 and 22 are detachable from the reel body, the worn seal member can be easily replaced.

  4 and 5 show a second embodiment of the present invention. In the present embodiment, the seal contact positions of the seal members 20 and 22 with respect to the cap 8 are different from those in the first embodiment. That is, the seal members 20 and 22 are not described in the first embodiment, but the side portions 20c and 22c that face the direction substantially orthogonal to the radial direction and can contact the cap 8 in a sealed state are provided. In the present embodiment, the seal members 20 and 22 can come into contact with the end surface of the stepped portion 8c of the cap 8 in a sealed state by the side surface portions 20c and 22c.

  In such a configuration, since the seal members 20 and 22 have side portions 20c and 22c that face the direction substantially orthogonal to the radial direction and can contact the cap 8 in a sealed state, the handle 10 As the left and right are rearranged, the seal members 20, 22 such as the sliding contact portions 20a, 22a deformed in a direction different from the radial direction by long-term use are sealed with the side portions 20c, 22c and the cap 8. It is possible to correct (in the normal radial direction) by contact (because the side surfaces 20c, 22c of the seal members 20, 22 are pressed by the end surface of the step 8c of the cap 8).

  6 and 7 show a third embodiment of the present invention. In this embodiment, the seal contact positions of the seal members 20 and 22 with respect to the cap 8 are different from those in the first and second embodiments. That is, the seal members 20 and 22 are not described in the first and second embodiments, but the outer surface portions 20d and 22d that can contact the cap 8 in a sealed state are opposed to the sliding contact portions 20a and 22a in the radial direction. In this embodiment, the seal members 20 and 22 can come into contact with the peripheral side surface 8d of the cap 8 in a sealed state.

  In such a configuration, the seal members 20 and 22 have outer surface portions 20d and 22d that can be brought into contact with the cap 8 in a sealed state on the radially outer side facing the sliding contact portions 20a and 22a in the radial direction. As the left and right of the handle 10 are rearranged, the load acting on the seal members 20 and 22 can be distributed in the radial direction (the seal pressure is distributed between the radially outer side and the inner side). Improves durability.
