Abstract
A spool has drag mechanism disposed on the rear, spool body, cover member, first sealing member, and second sealing member. The spool body has tubular bobbin trunk portion, and front/rear flange portions provided on the front/rear of the bobbin trunk portion. The drag mechanism includes: drag-handling unit that screws onto the fore end of the spool shaft; and friction unit disposed so as to contact the rear face of the rear flange. The rearward movement of the first friction unit is restricted by spool shaft. Cover member is installed on spool body to cover first friction unit from rear. First sealing member is fitted in between cover member and rear flange portion. Second sealing member is fitted in between spool shaft and cover member. Spool can control fluctuations in drag force due to liquids that seep into drag mechanism.
Claims18
A spinning-reel spool adapted to be mounted on a spool shaft that is installed in a spinning-reel reel body so as to be shiftable in a front-rear direction, said spinning-reel spool comprising:
- a spool body having a tubular bobbin-trunk portion that can be rotatably mounted on the spool shaft, and front and rear flange portions that are diametrically larger than said bobbin trunk portion and are provided respectively on front and rear portions of said bobbin trunk portion;
- a drag mechanism having a drag-handling unit that can be screwed onto a front end of the spool shaft so as to press said bobbin trunk portion, and a first friction unit that is disposed so as to contact a rear face of said rear flange portion, a rearward movement of said first friction unit being restricted by the spool shaft;
- a cover member installed non-rotatably on said spool body so as to cover said first friction unit from rear;
- first sealing means fitted in between said cover member and said spool body for sealing a gap therebetween;
- and
- second sealing means fitted in between the spool shaft and said cover member for sealing a gap therebetween.
A spinning reel, comprising:
- a reel unit that rotatably carries a handle, said reel unit having a spool shaft therein;
- a rotor rotatably carried on a front portion of said reel unit;
- and
- a spool disposed on said spool shaft so as to be shiftable front and back, said spool including
- a spool body having a tubular bobbin-trunk portion that can be rotatably mounted on said spool shaft, and front and rear flange portions that are diametrically larger than said bobbin trunk portion and are provided respectively on front and rear portions of said bobbin trunk portion;
- a drag mechanism having a drag-handling unit that can be screwed onto a front end of said spool shaft so as to press said bobbin trunk portion, and a first friction unit that is disposed so as to contact a rear face of said rear flange portion, a rearward movement of said first friction unit being restricted by said spool shaft;
- a cover member installed non-rotatably on said spool body so as to cover said first friction unit from rear;
- first sealing means fitted in between said cover member and said spool body for sealing a gap therebetween;
- and
- second sealing means fitted in between the spool shaft and said cover member for sealing a gap therebetween.
