Description

This invention relates to a collar component for a spinning reel. Conventional spinning reels comprise a reel body, a spool shaft, a pinion gear, a rotor, a rotor nut, a metal or resin collar component, and a bearing (see Patent Document 1). The rotor nut is positioned on the pinion gear at its front. The rotor nut restricts the forward movement of the rotor relative to the pinion gear. The rotor nut rotates integrally with the pinion gear. Generally, the collar member is formed in a cylindrical shape. The collar member is positioned on the spool shaft in front of the pinion gear. The bearing is positioned radially on the collar member. The bearing is positioned radially between the collar member and the rotor nut, rotatably supporting the rotor nut relative to the spool shaft. Japanese Patent Publication No. 2016-029949 A side view of a spinning reel according to an embodiment of the present invention.A cross-sectional view of a spinning reel.A partially enlarged view of the longitudinal cross-section of a spinning reel. As shown in Figure 1, a spinning reel 1 employing one embodiment of the present invention comprises a reel body 3, a handle 5, a spool 7, and a rotor 9. As shown in Figure 2, the spinning reel 1 further comprises a handle shaft 11, a drive gear 13, a spool shaft 15, an oscillating mechanism 17, a pinion gear 19, a rotor nut 21, a bearing 23, and a collar member 25. The spinning reel 1 further comprises a seal member 27 and a retaining member 29. As shown in Figure 1, the handle 5 is rotatably supported on the reel body 3. This embodiment shows an example where the handle 5 is positioned on the left side of the reel body 3. The handle 5 may also be positioned on the right side of the reel body 3. The handle 5 is mounted on the handle shaft 11. As shown in Figure 2, the handle shaft 11 is rotatably supported by the reel body 3. The drive gear 13 is mounted on the handle shaft 11 so as to be able to rotate integrally with the handle shaft 11. The drive gear 13 meshes with the pinion gear 19. As shown in Figure 1, fishing line is wound around the spool 7. The spool 7 is configured to move in the front-to-back direction relative to the reel body 3, together with the spool shaft 15. The spool 7 is mounted on the tip of the spool shaft 15. As shown in Figure 2, the spool shaft 15 is supported so as to be movable in the front-rear direction relative to the reel body 3. The spool shaft 15 is inserted into the inner circumference of the cylindrical pinion gear 19. The spool shaft 15 reciprocates in the front-rear direction relative to the reel body 3 by the operation of the oscillating mechanism 17. The spool shaft 15 has a spool axis X1. The front-rear and axial directions are the directions in which the spool axis X1 extends. The radial direction is the direction away from the spool axis X1. The circumferential and rotational directions are the directions around the spool axis X1. The oscillating mechanism 17 moves the spool shaft 15 in the forward and backward directions in conjunction with the rotation of the handle shaft 11. The oscillating mechanism 17 is located within the internal space of the reel body 3. The oscillating mechanism 17 includes a worm shaft 17a, a slider 17b, and an intermediate gear 17c. The worm shaft 17a is positioned parallel to the spool shaft 15. The worm shaft 17a is rotatably supported by the reel body 3. The slider 17b is fixed to the rear end of the spool shaft 15. The slider 17b engages with a groove in the worm shaft 17a and moves in the forward and backward direction due to the rotation of the worm shaft 17a. The intermediate gear 17c is fixed to the tip of the worm shaft 17a and engages with the pinion gear 19. In the oscillating mechanism 17, when the handle shaft 11 rotates due to the rotation of the handle 5, the drive gear 13, pinion gear 19, intermediate gear 17c, and worm shaft 17a rotate. This causes the slider 17b and spool shaft 15 to move in the forward and backward directions. The rotor 9 is used to wind the fishing line onto the spool 7. The rotor 9 is positioned at the front of the reel body 3. The rotor 9 is configured to rotate relative to the reel body 3. The rotor 9 is positioned radially outward from the pinion gear 19. The rotor 9 is integrally rotatably mounted with respect to the pinion gear 19. The pinion gear 19 is formed in a cylindrical shape. The pinion gear 19 is rotatably supported by the reel body 3. The pinion gear 19 is positioned radially outward from the spool shaft 15. The pinion gear 19 rotates relative to the spool shaft 15. For example, the pinion gear 19 rotates around the spool axis X1. The rotor 9 rotates in conjunction with the rotation of the pinion gear 19. The rotor nut 21 is used to restrict the forward movement of the rotor 9 relative to the pinion gear 19. The rotor nut 21 rotates relative to the spool shaft 15. For example, the rotor nut 21 rotates around the spool axis X1. As shown in Figure 3, the rotor nut 21 ha
