Description

  The present invention relates to a fishing spinning reel.

  Conventionally, a fishing spinning reel is configured to include a rotor that is driven to rotate by rotating a handle, and a spool that is wound with fishing line and that is driven to reciprocate back and forth. As generally known, the rotor is engaged with a drive gear (drive gear) mounted on a handle shaft (drive shaft), extends in a direction orthogonal to the handle shaft, and is rotatably supported. The spool shaft is rotationally driven by being fixed to the front end of the gear by a rotor nut, and the spool shaft is inserted into the pinion gear and reciprocated in the back and forth direction by a reciprocating device (oscillation mechanism) driven by a drive gear.

  The reciprocating device for converting the rotation of the steering wheel back and forth is accommodated inside the reel body of the fishing reel for fishing fishing, and can be made to have a long stroke by equalizing the back and forth reciprocating speed. In general, a screw shaft system has been widely adopted conventionally (see, for example, Patent Documents 1 to 4).

  This screw-type reciprocating device includes a screw shaft rotatably supported in the reel body and extending in parallel to the spool shaft, and a slider fixed to the rear end of the spool shaft. An oscillating gear engaged with the pinion gear is provided at the front end of the screw shaft, and a spiral cam groove is formed along the axial direction on the circumferential surface of the screw shaft. The engagement claws of the engagement elements housed and held in the slider are engaged. Therefore, when the handle is rotated, the screw shaft is rotationally driven through the drive gear, the pinion gear, and the oscillation gear, and the spool shaft is reciprocated back and forth through the slider engaged with the screw shaft. Ru.

  In addition, the movement is guided by supporting the slider which reciprocates back and forth by the guide shaft (pillar) arrange | positioned along a spool axial direction.

  By the way, the guide shaft which supports the slider and guides its movement is located on the lower side of the spool shaft in order to guide the slider smoothly in the back and forth direction by suppressing rattling and inclination of the slider. Although it is inserted in the slider, in the patent documents 1 and 2 mentioned above, since the guide shaft is guided and supported under the engaging element engaged with the screw shaft, the support portion of the guide shaft is secured The length of the reel body is increased in the vertical direction, and the size of the reel body is increased.

  On the other hand, in patent document 3 mentioned above, since the lower guide shaft of a spool shaft is provided between the engaging element which engages with a screw shaft, and a spool shaft, the spool shaft and engaging element only the support space of a guide shaft The length of the slider extending between them is increased, and the size and weight of the reel body are increased in the vertical direction. Further, in this arrangement relationship, since the guide shaft approaches the spool shaft, it is not possible to effectively suppress rattling in the rotational direction of the slider centering on the spool shaft while guiding and supporting the slider smoothly.

  Moreover, although the structure which arrange | positioned the guide shaft to the side of the engaging element engaged with a screw shaft in the downward area | region of a spool shaft is disclosed by patent document 4 mentioned above, a guide shaft approaches a spool shaft. Because of this arrangement, rattling in the rotational direction of the slider about the spool shaft can not be accurately and effectively suppressed. In addition, in this configuration, the screw member for integrating the slider with the spool shaft must be attached from the direction along the handle shaft, so that in view of avoiding interference with the drive gear (tooth surface), the reel body It will be necessary to make it thicker and larger in the width direction.

  The present invention has been made focusing on the above-described problems, and while achieving downsizing of the reel main body in the vertical direction, it is possible to accurately and effectively rattle the rotational direction of the slider centering on the spool shaft. It is an object of the present invention to provide a fishing spinning reel that can be suppressed.

  In order to achieve the above object, the present invention is provided in a drive shaft that is rotationally driven by a rotation operation of a handle rotatably supported on a reel body having a hook mounting portion at the top, and the reel body. A slide which has a helical shaft having a spiral groove on its outer peripheral surface and rotates in conjunction with the drive shaft, and a spool having a fishing line wound thereon at the front and accommodating and holding an engaging element engaged with the spiral groove. A fishing spinning reel comprising: a spool shaft having a mover provided at a rear portion thereof; and a guide shaft disposed along the spool shaft and guiding the slider in a moving direction. In the lower region opposite to the mounting portion, each of the screw shaft, the engagement element, and the guide shaft is positioned so as to at least partially overlap each other in the vertical direction as viewed along the drive shaft, Said At least the center of the id axis is positioned lower than the center of the screw shaft, characterized by at least partially overlapping it with the engager and vertical direction as viewed in the direction along the drive shaft.

  According to the fishing spinning reel having the above configuration, each of the screw shaft, the engaging element, and the guide shaft in the lower region opposite to the hook mounting portion with respect to the spool shaft is up and down each other in a direction along the drive shaft Since the reel main body can be downsized in the vertical direction because at least partial overlapping in the direction is possible, at least the center of the guide shaft is a screw shaft so that the guide shaft does not approach the spool shaft. Since the slider is positioned below the center, rattling in the rotational direction of the slider about the spool axis can be accurately and effectively suppressed. Moreover, since the guide shaft is at least partially overlapped with the engagement element in the vertical direction in a direction view along the drive shaft, that is, the guide shaft is not separately disposed below the engagement element, the reel body is in the vertical direction Can prevent the increase in size. That is, according to the above configuration, by the effective arrangement of each component, within the limited space, two purposes, ie, the purpose of achieving the downsizing of the reel body in the vertical direction, and the center of the spool shaft It is possible to simultaneously achieve the purpose of suppressing the backlash in the rotational direction of the sliding element accurately and effectively.

  In the above configuration, it is preferable that the slider be attached to the spool shaft by a screw member screwed from the upper side of the wedge mounting portion side orthogonal to the drive shaft. According to such a configuration, it is not necessary to consider interference with the drive gear (tooth surface) and the like, and enlargement of the reel body in the width direction can be avoided (the reel body can be narrowed).

  According to the present invention, it is possible to obtain a fishing spinning reel capable of accurately and effectively suppressing backlash in the rotational direction of the slider centering on the spool shaft while achieving downsizing of the reel body in the vertical direction.
