Description

  The present invention relates to a spinning reel, and more particularly to a spinning reel that is mounted on a fishing rod and can feed a fishing line forward.

  A spinning reel is generally a reel that winds a fishing line around an axis along the axial direction of a fishing rod. The spinning reel has a reel body that has a handle and is attached to a fishing rod, a spool that is movably mounted on the reel body, a rotor that guides fishing line to the spool, and a rotor that rotates in conjunction with the rotation of the handle. And a rotor drive mechanism.

  The rotor drive mechanism has a face gear that is non-rotatably attached to the handle and a pinion gear that meshes with the face gear. The pinion gear is a brass tubular body arranged along the front and rear of the reel body, and is rotatably supported by the reel body.

  A tooth portion that meshes with the face gear is formed at the outer peripheral rear portion of the pinion gear. A mounting portion for mounting the rotor in a non-rotatable manner is formed on the outer periphery of the front portion. A male screw portion is formed in the mounting portion, and a nut member for fixing the rotor to the male screw portion is mounted. A spool shaft with a spool attached to the tip penetrates the inner peripheral portion of the pinion gear, and the spool shaft is supported by the inner peripheral portion of the pinion gear so as to be movable back and forth. As a result, the spool shaft is attached to the reel body via the pinion gear so as to be movable back and forth. The spool shaft is a member made of stainless alloy and is supported in contact with the entire length of the inner peripheral surface of the pinion gear.

  In the spinning reel having such a configuration, since the spool shaft is supported by the entire length of the inner peripheral surface of the pinion gear, when the spool shaft is bent due to a large load acting on the spool, the inner periphery of the pinion gear The contact pressure with the spool shaft may increase and the frictional force between the spool shaft and the pinion gear may increase. When the frictional force between the two increases, the pinion gear becomes difficult to rotate, and the rotational efficiency of the rotor decreases and the fishing line winding efficiency decreases.

Therefore, in order to eliminate such problems, a clearance is provided between the inner peripheral surface of the pinion gear and the spool shaft, and the spool shaft is supported on the inner peripheral side of the front and rear portions of the pinion gear so as to be movable in the axial direction. One provided with a pair of support portions is known (for example, see Patent Document 1). With such a configuration, even if the spool shaft is bent, the frictional force between the spool shaft and the rotor is less likely to increase, so that a reduction in the rotational efficiency of the rotor can be suppressed.
JP-A-11-206287

  In the conventional spinning reel, by providing a pair of support portions for supporting the spool shaft on the inner peripheral side of the front and rear portions of the pinion gear, a gap is generated between the inner peripheral surface of the pinion gear and the spool shaft. Therefore, even if the spool shaft is bent, the frictional force between the spool shaft and the pinion gear is difficult to increase.

  However, since a pair of support portions are provided on the inner peripheral side of the front and rear portions of the pinion gear, the support portion of the pinion gear and the outer peripheral portion of the spool shaft come into contact with each other. Here, when the spool shaft moves back and forth, the pinion gear support and the outer periphery of the spool shaft come into sliding contact with each other, so that the contact pressure between the pinion gear support and the outer periphery of the spool shaft increases. This may increase the frictional force between the spool shaft and the pinion gear. When the frictional force between the spool shaft and the pinion gear increases, the pinion gear becomes difficult to rotate, which may further reduce the rotational efficiency of the rotor.

  An object of the present invention is to further suppress a decrease in rotational efficiency of a rotor in a spinning reel.

  A spinning reel according to a first aspect of the present invention is a spinning reel that is mounted on a fishing rod and can feed a fishing line forward, and is mounted on a fishing rod and has a handle, and is mounted on the reel body so as to be movable along the front-rear direction. A spool shaft, a spool that is attached to the front end of the spool shaft and on which the fishing line is wound, a rotor that is rotatably provided on the outer peripheral side of the spool, and a rotor that winds the fishing line around the spool, is rotatably supported by the reel body, and the handle cannot rotate. Mounted on the face, a pinion gear having a cylindrical portion, a tooth portion, and a mounting portion, a nut member mounted from the front end of the cylindrical portion to fix the rotor to the mounting portion, and mounted on the reel body A first support portion that rotatably supports the outer periphery of the cylindrical portion; and an outer periphery of the cylindrical portion that is mounted on the reel body and disposed rearward of the first support portion. A second support portion that is rotatably supported; a third support portion that is mounted on the reel body and supports the outer periphery of the spool shaft in front of the front end portion of the cylindrical portion; and an outer periphery of the spool shaft that is rearward of the rear end portion of the cylindrical portion. And a fourth support portion for supporting the. The cylindrical portion is a member through which the spool shaft passes through the inner peripheral portion with a gap. The tooth portion is a member that is provided on the outer periphery of the rear portion of the cylindrical portion and meshes with the face gear. The mounting portion is a member that is provided on the outer periphery of the front portion of the cylindrical portion and on which the rotor is mounted so as not to rotate.

  In this spinning reel, a pinion gear is provided by providing a third support portion and a fourth support portion that respectively support the outer periphery of the spool shaft at the front side from the front end portion of the cylindrical portion of the pinion gear and the rear end portion from the rear end portion of the cylindrical portion. A gap is generated over the entire length between the inner periphery of the shaft and the spool shaft. Accordingly, the inner peripheral portion of the pinion gear and the outer peripheral portion of the spool shaft are not in contact with each other, so that the frictional force between the spool shaft and the pinion gear is not further increased, thereby further suppressing the decrease in the rotational efficiency of the rotor. Can do.

In this case, since the second support portion supports both the rear end portion of the cylindrical portion and the fourth support portion, the spool shaft support structure is simplified.

  The spinning reel according to a third aspect of the present invention is the spinning reel of the second aspect, wherein the fourth support portion is arranged such that the rear end portion is positioned on the front side of the rear end portion of the second support portion. In this case, since the rear end portion of the fourth support portion is disposed so as to be located in front of the rear end portion of the second support portion, the fourth support portion can be disposed forward, and thus the spool shaft The front-rear length of the entire support structure can be shortened. Therefore, since the spool shaft support structure can be arranged in a compact manner, it is possible to prevent the entire reel from being enlarged. Furthermore, since the fourth support portion can be disposed in the front here, it is possible to prevent the fourth support portion from interfering with the face gear even when a large-diameter face gear is used.

  The spinning reel according to a fourth aspect of the present invention is the spinning reel of the first aspect, wherein the second support portion is disposed at a position that supports the front portion from the tooth portion of the cylindrical portion. The fourth support portion is attached to the reel body. In this case, since the first support part and the second support part are arranged at positions that support the front part from the tooth part of the cylindrical part, the front-rear length of the entire pinion gear can be shortened, so the large size of the entire reel Can be prevented.

  A spinning reel according to a fifth aspect is the spinning reel according to any one of the first to fourth aspects, wherein the first support portion and the second support portion are rolling bearings. In this case, generally, by using a rolling bearing having a low static friction coefficient, the pinion gear can be easily rotated with a relatively small force.

  The spinning reel according to a sixth aspect of the present invention is the spinning reel according to any one of the first to fifth aspects, wherein the fourth support portion is a sliding bearing. In this case, for example, by using a general-purpose sliding bearing such as a cylindrical bush member, the spool shaft can be supported with an inexpensive configuration.

  A spinning reel according to a seventh aspect is the spinning reel according to the sixth aspect, wherein the fourth support portion is a member made of synthetic resin. In this case, by using the bush member made of synthetic resin, it can be formed with a cheaper configuration and the corrosion resistance can be improved as compared with the bush member made of metal.

  A spinning reel according to an eighth aspect of the present invention is the spinning reel of any of the first to seventh aspects, wherein the spool shaft and the pinion gear are members made of stainless steel. In this case, the inner peripheral portion of the pinion gear and the outer peripheral portion of the spool shaft do not come into contact with each other. Therefore, when the support portion is provided on the inner peripheral portion of the pinion gear as in the prior art, the inner peripheral portion of the pinion gear and the spool shaft No contact with the outer periphery and seizure.

  According to the present invention, in the spinning reel, by providing the third support portion and the fourth support portion that respectively support the outer periphery of the spool shaft at the front side from the front end portion of the tubular portion and the rear end portion from the rear end portion of the tubular portion, Since the inner peripheral portion of the pinion gear and the outer peripheral portion of the spool shaft are not in contact with each other, the frictional force between the spool shaft and the pinion gear is not further increased, and therefore, the reduction in the rotational efficiency of the rotor can be further suppressed. .
