Description

  The present invention relates to a fishing spinning reel having a drive mechanism for winding a fishing line around a spool in accordance with a rotation operation of a handle.

  In general, a spinning reel used for fishing is rotated around the spool by a rotating rotor of the handle as the user rotates the handle, and the fishing line is wound around the spool of the spool. ing.

  The mechanism for transmitting the rotational motion of the handle to the rotor is mainly composed of a drive gear connected to the handle shaft and a pinion cylinder shaft provided at one end with a pinion gear engaged with the drive gear. The other end of the pinion cylinder shaft is connected to the rotor. The pinion cylinder shaft is rotatably attached to a support portion that is integrally molded so as to stand up from the casing member of the reel body via a bearing and a ball bearing.

  For example, Patent Document 1 describes a rotor drive mechanism. In this configuration, the pinion gear, which is the rotation shaft of the rotor, is formed in a cylindrical shape, and its front portion passes through the center portion of the rotor and is fixed to the rotor by a nut. Further, the pinion gear is rotatably supported by the reel main body through a bearing mounted on the rotation support portion and a bush mounted on the gear support, respectively, in the axial direction of the pinion gear. Yes.

  When the above-described spinning reel for fishing is attached to a fishing rod, when a fish hangs on a fishing line drawn from the spinning reel, that is, when an external load is applied to the reel, the rotor and the spool through the bale, A load is added to each. These loads are intermittently applied between the support portion and the pinion cylinder shaft and spool shaft that are directly connected to the rotor and spool. It is assumed that the pinion cylinder shaft and the spool shaft itself have sufficient strength against the load.

  These support parts are often formed so as to project integrally within the casing of the reel body, in order to ensure sufficient winding strength when a large load is applied and sufficient rigidity during machining during manufacturing. Therefore, it has a thickness suitable for the load, which is an obstacle in terms of reducing the weight and securing a space for arranging other components.

  In addition, the load applied to the reel body is moderated by the elasticity of the fishing rod, but the change in the abrupt force is relieved, but it is not applied in the same state over time, the applied force changes intermittently, and the handle Due to the rotation of the rotor by the rotation operation, for example, the pulling force works around the support portion that supports the pinion cylinder shaft. Further, the spool shaft is further moved back and forth, and a load in the axial direction is also generated. It should be noted that in the support portion that receives both the pinion cylinder shaft and the spool shaft, a load acting in these combined directions is applied, and in each support portion that receives the pinion cylinder shaft and the spool shaft separately, the different directions described above are applied. The load is on each.

  Therefore, when considering a structure with additional reinforcing parts, even if a reinforcing part to be reinforced is inserted, it moves around and back and forth, and loads are applied sequentially from different directions, so if it can not act to relieve the load, There is also a possibility that bending and shaking may occur between the pinion cylinder shaft and the spool shaft and these supporting portions, and a situation in which a stable winding operation is not realized is also assumed.

  Further, in the configuration in which only the reinforcing member is molded only from the support part to the front wall of the casing of the reel unit, contraction due to a change in heat occurs at the time of injection molding, and a force drawn to the front side works, so that the support part is on the front side. Deformation such as tilting occurs, resulting in a problem with the accuracy of the finished dimensions.

  Therefore, the present invention reduces the load applied to the drive mechanism from different directions sequentially by reinforcement acting from a plurality of directions, realizes weight reduction while maintaining the strength, and realizes a suitable winding operation. An object is to provide a spinning reel.

In order to achieve the above object, a spinning reel for fishing according to an embodiment of the present invention includes a reel body having a housing portion, a spool that is disposed on the front side of the reel body and winds and holds a fishing line, A rotor portion having a bale for winding the fishing line around a spool; a drive mechanism that is housed in the housing portion and includes a drive shaft that receives a rotation operation of a handle and rotates in connection with the rotor portion; and the drive An oscillating mechanism including a spool shaft connected to the spool to move back and forth, and a driving force transmitted from the mechanism; and provided so as to extend integrally from an inner wall side surface of the housing portion; a support portion for rotatably supporting by fitted to the spool shaft, said extending integrally formed leads to the front wall lower in the casing on the front side from the upper end of the support portion A first reinforcing portion, a second angle formed at a predetermined angle with the first reinforcing portion, extending upward from the upper end portion of the supporting portion, and connected to the upper portion of the front wall of the housing portion.
