Abstract: An object of this invention is to provide a fishing line spool which is capable of securely holding a fishing line wound around the fishing line spool and reduced in cost. The fishing line spool is provided with a hollow core, a pair of flanges, and doors which are formed integrally. The doors are provided on outer peripheries of the flanges. The doors change postures between a closed posture in which tips of the doors are brought into contact to each other and an open posture in which the tips depart from each other. Each of the doors is formed from an elastic disc. Each of the doors is so curved that the tips of the doors press against each other in the closed posture. A pinching plate for pinching a fishing line is provided on the tip of each of the doors. The hollow core, the flanges, and the doors are made from a biodegradable resin.

Abstract: A spool includes a spindle (8a) perpendicularly extending from a major surface (4a) of a base plate (4). A bobbin (16a) is fitted over the spindle (8a). The bobbin (16a) includes a short cylindrical member (18a) and a flange (20a) contacting the major surface (4a) of the base plate (4). A coil of fishing line (22a) is fitted over the bobbin (16a). A short cylindrical member (10a) of a flange member is fitted into the spindle (8a). A flange (12a) is formed along the peripheral edge of the cylindrical member (10a).

Abstract: This spool 10 is provided with a first spool unit 11, a second spool unit 12, and a support mechanism 13 for supporting the second spool unit 12. The first spool unit 11 is provided with a short cylindrical unit 14, and a fishing line is wound around the short cylindrical unit 14. The second spool unit 12 is provided with a short cylindrical unit 25, and another fishing line is wound around the short cylindrical unit 25. The first spool unit 11 is provided with a support shaft 18, and the second spool unit 12 is provided with a receiver shaft 29. The support mechanism 13 is constituted of the support shaft 18 and the receiver shaft 29. The receiver shaft 29 is coupled to the support shaft 18 so that the second spool unit 12 is housed inside the first spool unit 11. The second spool unit 12 rotates inside the first spool unit 11. The support shaft 18 is provided with a stopper 22 which prevents an unintentional removal of the second spool unit 12 from the first spool unit 11.

Abstract: A spool (10) for fishing line according to the present invention has a main body (11) including a first flange (14) and a hollow cylindrical portion (13) formed integral with each other, and a second flange (12), all formed of resin or metal. The second flange (12) is snugly fitted into the bore in the cylindrical portion (13). The cylindrical portion (13) can be tapered to have a frustoconical shape. Through-holes (15, 20) are formed in the first and second flanges (14, 12). Also, cuttings (17, 23) are formed in the outer peripheries of the first and second flanges (14, 20).

Abstract: A spool for fishing line comprises: a short-cylinder core portion; and a pair of flange portions provided at opposite end portions of the core portion, and the core portion and the flange portions are made of paper.
