Description

  The present invention relates to a handle mounting structure, and more particularly to a spinning reel handle mounting structure in which a handle shaft is mounted on a master gear.

  In general, a spinning reel has a reel body mounted on a fishing rod, a rotor rotatably supported on the reel body, and a spool that is provided in front of the rotor and on which an fishing line is wound around an outer periphery. The rotor rotates integrally with a pinion gear provided on the outer peripheral side of the spool shaft. The spool is reciprocated back and forth by an oscillating mechanism having an intermediate gear meshing with the pinion gear. The pinion gear meshes with a master gear having a shaft portion orthogonal to the pinion gear, and rotates by rotation of the handle. The outer periphery of both ends of the shaft portion of the master gear is rotatably mounted on the reel body by a bearing or the like. A handle shaft portion of the handle is mounted on the shaft portion of the master gear, and a gear portion is provided on the outer periphery. As such a spinning reel, one in which a handle shaft portion of a handle is screwed into a shaft portion of a master gear is known (see, for example, Patent Document 1).

  In such a handle mounting structure, when the handle is attached to the shaft portion of the master gear, the tip portion of the handle may be pushed in, and the end portion of the shaft portion may be buckled. As described above, when the end portion of the shaft portion buckles, the end portion of the shaft portion may swell radially outward. Therefore, in order to prevent the end portion of the shaft portion of the master gear from buckling, it is known that a hard metal annular portion is mounted on the outer periphery of the end portion of the shaft portion of the master gear ( For example, see Patent Document 2). In this case, even if the distal end of the handle shaft portion of the handle is pushed in, the end portion of the shaft portion swells radially outward by mounting the annular portion on the outer periphery of the end portion of the shaft portion of the master gear. Can be suppressed.

  In the conventional handle mounting structure, the annular portion is attached to the outer periphery of the end portion of the shaft portion of the master gear, so that buckling of the end portion of the shaft portion of the master gear can be prevented. However, here, since the annular portion is only attached to the outer periphery of the end portion of the shaft portion of the master gear, it is possible to push the tip end portion of the handle shaft portion of the handle more strongly. For this reason, if the tip of the handle shaft part of the handle is pushed more strongly, the end part of the shaft part is radially outward even though the annular part is attached to the outer periphery of the end part of the master gear shaft part. May swell slightly. In this way, when the end of the shaft portion of the master gear is slightly buckled, it is possible to push the tip end portion of the handle shaft portion of the handle more strongly. There is a risk that buckling will further progress.

  An object of the present invention is to prevent the buckling of the end portion of the handle shaft portion from proceeding when the handle shaft portion is screwed into the master gear in the spinning reel handle mounting structure.

  In the spinning reel handle mounting structure according to the first aspect of the present invention, the rotation of the screw-in type handle is transmitted to the rotor via the pinion gear to the master gear rotatably supported by the bearing on the reel body of the spinning reel. A spinning reel handle mounting structure on which a handle shaft portion is mounted, and includes a handle shaft portion, a master gear, and a tubular portion. The handle shaft portion has a male screw portion formed at the outer peripheral portion at the distal end portion. The master gear has a shaft portion and a gear portion. The shaft portion has a female screw portion into which the male screw portion is screwed at both ends, and is provided rotatably on the reel body. A gear part is provided in the axial direction inner periphery from the rotation support part by the bearing of a shaft part, and meshes with a pinion gear. The cylindrical part has a main body cylindrical part and a buckling progress preventing part. The main body cylinder portion is attached to the outer periphery of the shaft portion at a position away from the rotation support portion of the handle shaft portion outward in the axial direction. The buckling progress prevention part is integrally formed at the tip of the main body cylinder part, and when the handle shaft part is screwed in, it contacts from the end part of the main body cylinder part of the shaft part to the outer peripheral part of the shaft part outside the axial direction. So that it can contact the inner peripheral end of the bearing.

  In this handle mounting structure, it is integrally formed at the tip of the main body cylinder part, and when the handle shaft part is screwed in, it contacts from the end part of the main body cylinder part of the shaft part to the outer peripheral part on the axially outer side from the rotation support part of the shaft part. And a buckling progress preventing portion that can contact the inner peripheral side end portion of the bearing when the handle shaft portion is screwed in is provided. Here, when the handle shaft part is screwed in, the buckling progress prevention part comes into contact with the inner peripheral side end part of the bearing, so that the inner peripheral side end part of the bearing functions as a stopper for the cylindrical part. Thus, the handle shaft portion fixed to the cylindrical portion is not further screwed. Therefore, the handle shaft portion is not further screwed in, so that when the handle shaft portion is screwed into the master gear, the buckling of the end portion of the handle shaft portion can be prevented.

  Further, here, since the conventional cylindrical portion that is sandwiched between the handle arm and the master gear and is mounted on the outer periphery of the handle shaft portion can be provided with a buckling progress preventing portion, the end of the shaft portion of the master gear can be provided. There is no need to provide an annular portion on the outer periphery of the portion. Therefore, it is possible to prevent the buckling of the handle shaft end from proceeding with a simple configuration.

  The handle mounting structure according to a second aspect of the present invention is the handle mounting structure according to the first aspect of the present invention, wherein the buckling progress preventing portion is integrally formed so as to project annularly at the tip end portion of the main body cylinder portion. In this case, when the handle shaft is screwed in, the length of the protruding part of the buckling progress prevention part is longer than the length from the end of the shaft part to the inner peripheral end of the bearing. Can be easily formed so as to be in contact with the inner peripheral end of the bearing.

  The handle mounting structure according to a third aspect of the present invention is the handle mounting structure according to the first or second aspect, wherein the main body cylindrical portion is provided integrally with the inner cylindrical portion mounted on the outer peripheral side of the handle shaft portion and the outer peripheral portion of the inner cylindrical portion. An outer cylindrical portion. The buckling progress preventing portion is integrally formed with the tip portion of the inner cylinder portion. In this case, the outer cylindrical portion can function as a cover member that covers the handle shaft portion, and the inner cylindrical portion can function as a member for holding the main body cylindrical portion and the buckling progress preventing portion.

  The handle mounting structure according to a fourth aspect of the present invention is the handle mounting structure of the third aspect, wherein the outer diameter of the buckling progress preventing portion is the same as the outer diameter of the inner cylindrical portion. In this case, the buckling progress preventing portion can be formed simply by projecting the inner cylindrical portion as it is.

  The handle mounting structure according to a fifth aspect of the present invention is the handle mounting structure according to any one of the first to fourth aspects, wherein the shaft portion has a larger diameter than the female screw portion at one end when the handle shaft portion is mounted on the female screw portion. It has the hole part formed in this way. The buckling progress prevention part can contact the inner peripheral side end part of the one side bearing in which the hole is formed. In this case, it is a handle that can screw one handle shaft part on both the left and right sides, and the inner peripheral side of the bearing on the side provided with a recess as an escape part where the male screw part of the handle shaft part is not screwed When the handle shaft portion is screwed into the end portion, the buckling progress preventing portion comes into contact. Here, when the handle shaft part is screwed into the inner peripheral side end of the bearing on the side of the shaft part on the side where the concave part is provided, the buckling progress preventing part is relatively weak and easily buckled. Since they come into contact with each other, it is possible to reliably prevent the buckling of the end portion of the handle shaft portion from proceeding.

  The handle attachment structure according to a sixth aspect of the present invention is the handle attachment structure of the fifth aspect, wherein the buckling progress preventing portion cannot contact the inner peripheral side end portion of the other side bearing in which no hole is formed. In this case, the buckling progress preventing portion does not come into contact when the handle shaft portion is screwed into the inner peripheral end portion of the bearing on the side where the concave portion is not provided at the end portion, which is relatively strong and difficult to buckle. Therefore, it is only necessary to consider the length of the buckling progress preventing portion on one side, and therefore, the length of the buckling progress preventing portion can be easily designed.

  According to the present invention, in the handle mounting structure of the spinning reel, the shaft is integrally formed at the distal end portion of the main body cylinder portion, and when the handle shaft portion is screwed, from the end portion of the main body cylinder portion of the shaft portion to the shaft from the rotation support portion of the shaft portion. A buckling progress prevention part that is mounted so as to be in contact with the outer peripheral part on the outer side in the direction and can contact the inner peripheral side end of the bearing when the handle shaft part is screwed in is further screwed in. Therefore, when the handle shaft portion is screwed into the master gear, buckling of the end portion of the handle shaft portion can be prevented.
