  In the conventional spinning reel, the outer peripheral surfaces of the attachment portions of the one-way clutch assembly and the reel body are covered with a thin cylindrical seal ring made of synthetic resin. For this reason, there is a possibility that the seal ring is deteriorated due to secular change and the waterproof performance is lowered.

  An object of the present invention is to provide a spinning reel in which a one-way clutch assembly of a reverse rotation prevention mechanism is fixed to a front portion of a reel body, so that liquid can be more reliably prevented from entering between the one-way clutch assembly and the reel body. There is to do.

  The spinning reel according to the present invention is a reel that feeds a fishing line forward. The spinning reel includes a handle, a reel body, a rotor, a spool, a rotor drive mechanism, and a reverse rotation prevention mechanism. The reel body has a rod mounting portion on which a fishing rod can be mounted and a circular mounting portion provided at the front portion, and rotatably supports the handle. The rotor has a cylindrical mounting portion and is rotatably mounted on the reel body. The spool is attached to the reel body so as to be movable back and forth, and a fishing line is wound around the rotor. The rotor drive mechanism has a face gear tooth, a drive gear that rotates in conjunction with the rotation of the handle, and a cylindrical pinion gear that is coupled to the front portion so that the rotor mounting portion is integrally rotatable and meshes with the drive gear. Have. The reverse rotation prevention mechanism prohibits rotation of the rotor in the yarn unwinding direction. The reverse rotation prevention mechanism includes a one-way clutch assembly, a cover member, a first seal member, and a second seal member. The one-way clutch assembly is an inner ring idle type that is detachably attached to the attachment portion of the reel body. The cover member covers the front surface of the one-way clutch assembly and is integrally formed on the ring-shaped bottom portion through which the pinion gear can pass and the outer peripheral portion of the bottom portion, and covers the outer peripheral portion of the one-way clutch assembly and the outer peripheral portion of the mounting portion. It is made of a rigid body having a cylindrical portion. The first seal member seals the gap between the attachment portion and the cylindrical portion. The second seal member seals a gap between the mounting portion of the rotor and the bottom portion of the cover member.

  In this spinning reel, the outer peripheral part of the one-way clutch assembly and the outer peripheral part of the mounting part are covered by the cylindrical part of the cover member made of a rigid body, and the front surface of the one-way clutch assembly is covered by the bottom part of the cover member. Further, the gap between the cylindrical portion and the attachment portion is sealed by the first seal member, and the gap between the mounting portion of the rotor attached to the pinion gear and the bottom portion of the cover member is sealed by the second seal member. Here, the mounting portion and the outer periphery of the one-way clutch assembly are covered by a rigid cover member, the front surface of the one-way clutch assembly is covered, and a gap between the mounting portion and the cylindrical portion of the cover member is formed by the first seal member. Seal. Further, the gap between the bottom portion of the cover member and the mounting portion of the rotor is sealed by the second seal member. For this reason, the cover member is unlikely to deteriorate over time, and liquid can be more reliably prevented from entering between the one-way clutch assembly and the reel body.

  The first seal member may be mounted in an annular groove formed on the outer peripheral portion of the attachment portion, and may be disposed in contact with the inner peripheral surface of the cylindrical portion. In this case, since the first seal member is attached to the annular groove, it is easy to attach the cover member to the attachment portion.

  The annular groove may be arranged behind the front surface of the attachment portion. The first seal member is an O-ring attached to the annular groove. In this case, since a general-purpose O-ring can be used for sealing, the sealing cost can be reduced.

  The one-way clutch assembly includes a circular case member that can be attached to the attachment portion and has an outer peripheral portion, an inner ring that is connected to the pinion gear so as to be integrally rotatable, an outer ring that is non-rotatably provided on the case member, and an inner ring and an outer ring And a plurality of rolling elements arranged between the two. The cover member is provided on the front surface of the bottom portion of the first cover portion, the first cover portion having a bottom portion and a cylindrical portion that are disposed on the front surface of the outer ring and prevents the rolling elements from coming off, A ring-shaped second cover portion that sandwiches the outer peripheral portion of the second seal member therebetween. In this case, since the cover member is divided into two members, it is not necessary to expand and contract the second seal member, and the second seal member can be easily attached.

  The one-way clutch assembly includes a circular case member that can be attached to the attachment portion and has an outer peripheral portion, an inner ring that is connected to the pinion gear so as to be integrally rotatable, an outer ring that is non-rotatably provided on the case member, and an inner ring and an outer ring And a plurality of rolling elements arranged between the two. The cover member is disposed in a gap between the bottom portion and the outer ring, the first cover portion having a bottom portion and a tubular portion disposed with a gap in front of the outer ring, and prevents the rolling elements from being detached, and the first inner portion A second cover portion that sandwiches the outer peripheral portion of the second seal member with the one cover portion. In this case, since the cover member is divided into two members, it is not necessary to expand and contract the second seal member, and the second seal member can be easily attached.

  The annular groove may be arranged so as to be connected to the front surface of the attachment portion. The first seal member is an O-ring that contacts the rear surface of the tubular one-way clutch assembly. In this case, in addition to the clearance between the outer peripheral portion of the mounting portion and the cylindrical portion, the clearance between the mounting portion and the one-way clutch assembly can also be sealed with the O-ring.

  The second seal member may include a ring portion that is attached to the inner peripheral portion of the bottom portion, and a tapered lip portion that is integrally formed with the ring portion and contacts the outer peripheral surface of the attachment portion. In this case, since the contact area of the lip portion that contacts the mounting portion of the rotating rotor is reduced, it is possible to suppress a decrease in the rotational performance of the rotor.

  The reverse rotation prevention mechanism may further include a first fixing member for fixing the case member and the cover member to the front surface of the attachment portion. In this case, the one-way clutch assembly and the first cover member can be collectively fixed to the attachment portion by the first fixing member.

  The first fixing member may include a plurality of first screw members that pass through the cover member and the case member and are screwed into the mounting portion and arranged at intervals in the circumferential direction. In this case, the one-way clutch assembly and the cover member can be fixed to the mounting portion by screwing the first screw member into the mounting portion.

  The reverse rotation prevention mechanism may further include a second fixing member that fixes the cover member to the case member. In this case, since the cover member can be fixed to the case member by the second fixing member, the cover member and the one-way clutch assembly can be unitized. For this reason, even if the first fixing member is removed, the one-way clutch assembly does not fall apart. Further, after the one-way clutch assembly is unitized, it can be attached to the attachment portion by the first fixing member.

  The second fixing member may include a plurality of second screw members that pass through the cover member and are screwed into the case member, and are spaced apart in the circumferential direction between the first screw members. In this case, the one-way clutch assembly including the cover member can be unitized by screwing the second screw member disposed between the first screw members into the case member.

  According to the present invention, the rigid cover member covers the mounting portion and the outer periphery of the one-way clutch assembly, covers the front surface of the one-way clutch assembly, and the first seal member covers the mounting portion and the cylindrical portion of the cover member. Seal the gap. Further, the gap between the bottom portion of the cover member and the mounting portion of the rotor is sealed by the second seal member. For this reason, the cover member is unlikely to deteriorate over time, and liquid can be more reliably prevented from entering between the one-way clutch assembly and the reel body.
