  In the conventional single-bearing reel, the outer peripheral side of the flange portion of the spool is covered with the cover portion of the reel body, thereby protecting the outer periphery of the flange portion of the spool and preventing foreign matter from entering the inside of the reel body. Further, in the conventional single-bearing reel, the fishing line wound around the spool body of the spool is regulated so as not to enter the reel body.

  On the other hand, when the angler performs fishing using a single bearing reel, the angler kneads the bait by hand to form a dumpling. The angler often operates the reel with the fishing bait attached to the hand, and the fishing bait adheres to the spool (the fishing line wound around the spool) from the angler's hand. Then, this fishing bait may enter between the flange portion of the spool and the cover portion. This fishing bait may cause friction between the flange portion and the cover portion, which may hinder smooth rotation of the spool. Further, the fishing bait attached to the spool may enter the inside of the reel body. In this case, abnormal noise may occur when the spool is rotated.

  In addition, when trying to remove foreign matter such as fishing bait adhering to the cover part during maintenance after actual fishing, not only is it troublesome, but also cleaning liquid (water, etc.) may remain on the reel.

  An object of the present invention is to provide a single-bearing reel that prevents entry of foreign matter into the inside of a reel body and can be quickly removed when foreign matter enters.

  The single-bearing reel according to the first aspect includes a spool, a reel body, and a handle portion. The spool has a bobbin trunk and a flange. The bobbin trunk is the part where the fishing line is wound. The flange portion is provided at both ends of the bobbin trunk. The reel main body includes a main body portion, a support shaft, and a cover portion.

Note that the pinion gear 36 is returned from the clutch-off position to the clutch-on position by a return mechanism (not shown).

<Foreign matter removal operation during spool rotation>
When the angler rotates the handle 12, the spool 13 rotates. For example, even if a foreign object such as fishing bait adheres to the fishing line wound around the outer flange portion 17a and / or the bobbin trunk 16 of the spool 13, when the spool 13 rotates, centrifugal force acts on the bait. The centrifugal bait removes the fishing bait adhering to the spool to the outside. However, in the conventional configuration, when fishing bait enters between the inner flange portion 17b of the spool 13 and the flange portion 21e of the frame 21, the fishing bait accumulates between the inner flange portion 17b and the flange portion 21e. Further, when the amount of fishing bait increases, the bait slides with the inner flange portion 17b and / or the ridge portion 21e, which becomes a factor that hinders the smooth rotation of the spool 13. Further, when this fishing bait has entered the reel main body 11, the bait interferes with the rotation transmission mechanism and the like, which may cause abnormal noise and / or rotation failure.

  On the other hand, in the single bearing reel 10, when the fisherman rotates the handle 12 in a state where the bait has entered between the inner flange portion 17 b of the spool 13 and the flange portion 21 e of the frame 21, By rotation of the flange portion 17b, centrifugal force acts on the fishing bait, and this fishing bait is directly removed from the plurality of holes 21g (121g, 221g, 321g). When centrifugal force acts on the fishing bait, the bait abuts on the groove 21f and is guided along the groove 21f to the holes 21g (121g, 221g, 321g). And a fishing bait is removed from each hole 21g (121g, 221g, 321g).

  Particularly, the third hole portion 321g is provided in the groove portion 21f of the flange portion 21e below the spool shaft 14 (in the direction of gravity). For this reason, even when the spool 13 is not rotating, the fishing bait is guided to the third hole portion 321g along the groove portion 21f by, for example, water in the groove portion 21f. Then, the fishing bait is removed from the third hole 321g. The water in the groove portion 21f includes seawater at the time of fishing and / or washing water at the time of maintenance.

  In this way, in this single bearing reel 10, since the bait is removed from the hole 21g, the invasion of the bait into the inside of the reel body 11, for example, the invasion of the bait between the frame 21 and the spool 13, Can be prevented.

  Further, in the single bearing reel 10, at the time of maintenance, the spool 13 is detached from the spool shaft 14 by the one-touch attaching / detaching mechanism 52, thereby making it possible to access the inner peripheral portion of the flange portion 21e. In this case, the maintenance can be easily performed only by removing the fishing bait remaining in the groove 21f and / or each hole 21g (121g, 221g, 321g).
