  The sealing member of the conventional spinning reel has one annular lip portion on the inner peripheral portion. However, in order to further improve the waterproof performance, it is considered that two annular lip portions are provided on the inner peripheral portion. It is done. By providing two lip portions in this way, for example, even if water is submerged from the first lip portion disposed on the inner peripheral portion on the axial opening side, two lip portions disposed on the opposite side to the axial opening side are used. The eye lip can prevent water from entering the roller clutch.

  However, even when two lip portions are provided, there is a possibility that the first lip portion may be submerged and the second lip portion may be submerged. In this case, there is a risk of water entering the roller clutch.

  Further, when two annular lip portions are provided on the inner peripheral portion, the two lip portions come into contact with the outer peripheral surface of the boss portion of the rotor. Therefore, there is a possibility that the rotational friction of the rotor increases due to an increase in contact friction. .

  2 and 3, the spool shaft 15 is a shaft member made of a stainless alloy, the spool 4 is connected to the front end portion via a drag mechanism 60, and an oscillating mechanism to be described later is connected to the rear end portion. Six sliders 22 are fixed. The spool shaft 15 penetrates the inner peripheral portion of the pinion gear 12, and the outer periphery of the spool shaft 15 at the front side from the front portion 12a of the cylindrical portion 12b and the rear portion from the rear portion 12f of the cylindrical portion 12b is respectively the third bearing 14c. And it is rotatably supported by the fourth bearing 14d.

  As shown in FIG. 3, the third bearing 14 c is a rolling bearing attached to the outer periphery of the spool shaft 15. As for the 3rd bearing 14c, an outer ring | wheel is mounted | worn with the front end side inner peripheral part of the nut member 13, and an inner ring | wheel is mounted | worn with the outer periphery of the spool shaft 15 ahead of the front part 12a of the cylindrical part 12b.

  As shown in FIG. 3, the fourth bearing 14d is a synthetic resin cylindrical member, and is a general-purpose sliding bearing such as a bush member. The outer periphery of the fourth bearing 14d is attached to the inner periphery of the rear end of the second bearing 14b, and the inner periphery is attached to the outer periphery of the spool shaft 15 behind the rear portion 12f of the cylindrical portion 12b. Here, since the second bearing 14b supports both the rear portion 12f of the cylindrical portion 12b and the fourth bearing 14d, the support structure of the spool shaft 15 is simplified. Further, the fourth bearing 14d is disposed so that the rear end portion is positioned on the front side of the rear end portion of the second bearing 14b. For this reason, since the 4th bearing 14d can be arrange | positioned ahead, the front-back length of the whole support structure of the spool shaft 15 can be shortened.

  2, the oscillating mechanism 6 is a mechanism for moving the spool 4 in the same direction by moving the spool shaft 15 connected to the center of the spool 4 via the drag mechanism 60 in the front-rear direction. is there. The oscillating mechanism 6 is of a traverse cam type, and includes an intermediate gear 20 that meshes with the tooth portion 12c of the pinion gear 12, and a screw shaft 21 that is rotatably mounted on the reel body 2a around an axis parallel to the spool shaft 15. And a slider 22 that moves back and forth by the rotation of the screw shaft 21. A rear end portion of the spool shaft 15 is attached to the slider 22 so as not to rotate but to move in the axial direction.

  Next, the operation and operation of the reel will be described in detail.

  At the time of casting, the rotor 3 is set in a reverse rotation prohibition state by a non-reverse rotation prevention mechanism (not shown), and the bail arm 17 is reversed to the yarn releasing posture by holding the bail arm by hand. In a state where the bail arm 17 falls to the line releasing posture, the fishing line from the spool 4 can be easily fed out.

  In this state, the fishing rod is cast while hooking the fishing line with the index finger of the hand holding the fishing rod. The fishing line is then released vigorously due to the weight of the device.

  After casting, when the handle 1 is rotated in the yarn winding direction while the bail arm 17 is maintained in the yarn releasing posture, the rotor 3 is rotated in the yarn winding direction by the rotor drive mechanism 5. When the rotor 3 rotates in the yarn winding direction, the bail arm 17 returns to the yarn winding posture by the bale reversing mechanism 18.

  In such a spinning reel, the first waterproof member 70 includes the first lip portion 72, the second lip portion 73 that contacts the outer peripheral portion of the cap member 33c of the rotor 3, and the first lip of the outer peripheral portion of the cap member 33c. And a grease holding portion 74 that is provided between the portion 72 and the second lip portion 73 and holds the grease 90. The second waterproof member 80 includes a first lip portion 83, a second lip portion 84 that contacts the outer peripheral portion of the pinion gear 12, and a first lip portion 83 and a second lip portion 84 on the outer peripheral portion of the pinion gear 12. And a grease holding portion 85 that holds the grease 90 therebetween. Here, the second lip portion 73 of the first waterproof member 70 and the second lip portion 84 of the second waterproof member 80 are in contact with the outer peripheral portion of the cap member 33c of the rotor 3 and the pinion gear 12. Compared to the configuration, the rotational friction of the cap member 33c and the pinion gear 12 is less likely to increase. Further, here, the grease holding portion 74 provided between the first lip portion 72 and the second lip portion 73 on the outer peripheral portion of the cap member 33c, and the first lip portion 83 and the first lip portion 83 on the outer peripheral portion of the pinion gear 12 are provided. Since the grease 90 is held by the grease holding portion 85 provided between the two lip portions 84, the waterproof performance of the roller clutch 51 and the first bearing 14a can be improved.
