[Industrial applications]

 According to the present invention, a screw shaft that is rotated by a rotational driving force from a handle, an engagement piece into which an engagement portion at an end of the screw shaft engages with a spiral groove of the screw shaft, and the engagement piece are internally provided. However, the present invention relates to an improvement of a reciprocating operation mechanism of a fishing reel including a movable member that reciprocates by a force from an engaging piece.

[0002]

[Prior art]

 Conventionally, as the reciprocating mechanism constructed as described above, the one used in the oscillating mechanism of the spinning reel as shown in Japanese Utility Model Publication No. 4-1806 or the one disclosed in Japanese Utility Model Publication No. 62-148063. Thus, there are those used for the level wind mechanism of the double bearing reel.

[0003]

[Problems to be solved by the device]

 Here, of the conventional examples used for spinning reels, in the structure in which the engaging portion at one end of the engaging portion is engaged with the spiral groove of the screw shaft, the engagement is performed when the spool shaft is moved forward. Since the posture of the spiral groove in which the part engages and the posture of the spiral groove in which the engagement part engages when retracting the spool shaft are different, rotate the engaging piece with respect to the movable member so as to follow each posture. By freely setting and setting the thickness of the engaging part to be slightly smaller than the width of the spiral groove, the posture of the engaging part can be smoothly changed at the switching point between forward and backward movements, In addition, it is configured so that it is difficult for it to bend.

However, in such a structure in which the engaging piece is rotatably provided with respect to the movable member and the engaging portion having a thickness narrower than the spiral groove is engaged, the engaging piece is engaged even when the screw shaft does not rotate. The spool shaft can be displaced slightly in the front and rear directions by the flexibility (rattling) between the portion and the spiral groove. For example, when the spool position changes due to this flexibility during the fishing line winding operation. May increase the contact resistance between the fishing lines wound on the spool during casting due to the fishing line not being wound in the proper position. This inconvenience becomes remarkable when the tension acting on the fishing line is small, or when the tension of the fishing line decreases during winding of the fishing line, and there is room for improvement. Such inconvenience also occurs in the level winding mechanism of the double bearing reel, and appropriate improvement is desired. The object of the present invention is to move the movable member in a stable position with respect to the screw shaft without causing rattling even when an external force is applied, without impairing the smooth operation of the screw shaft and the engaging piece. The point is to rationalize the mechanism.

[0005]

[Means for Solving the Problems]

 The features of the present invention are, as described at the beginning, a screw shaft that is rotatably operated by a rotational driving force from a handle, and an engaging piece in which an engaging portion of an end portion engages with a spiral groove of the screw shaft. In the reciprocating operation mechanism of the fishing reel, the reciprocating operation mechanism includes a movable member that internally reciprocates the engaging piece and reciprocates by a force from the engaging piece. It is formed by setting the longitudinal direction in an orthogonal posture, and the engaging piece is rotatably supported with respect to the movable member around its axis, and at the same time, the engaging piece is provided around the axis of the engaging piece. It is provided with an urging means for rotationally urging the engaging piece, and its action and effect are as follows.

[0006]

[Action]

 When the above features are configured in the oscillating mechanism of the spinning reel as shown in FIGS. 1 to 5, for example, the urging force from the urging means S acts in the direction of rotating the engaging piece 12, so that the handle is operated. Even when the screw shaft 11 rotates, as shown in FIG. 2, both ends of the engaging portion 12A in the longitudinal direction move in a state of sliding contact with the side edges of the spiral groove 11A, and as a result, in the axial direction of the spool shaft 14. Even when an external force is applied, the relative displacement between the engaging portion 12A and the spiral groove 11A is prevented to prevent the winding position of the fishing line from deviating from the spool 5 from occurring, and further to prevent the twisting during operation. Even if the situation occurs, the engaging piece 12 rotates against the urging force of the urging means S to eliminate the occurrence of twisting. That is, in the present invention, the thickness of the engaging portion 12A is made smaller than the width of the spiral groove 11A to form a gap between them, which allows smooth operation in the same manner as in the prior art. The movable member 13 is maintained in an appropriate position by eliminating the rattling, and when a large force acts between the spiral groove 11A and the engaging portion 12A, this force is generated by the rotation of the engaging piece 12. This will prevent the phenomenon that a large force acts on each of them.

[0007]

[Effect of device]

 Therefore, there is a rational mechanism that stabilizes the position of the movable member with respect to the screw shaft without causing rattling even when external force acts, without impairing the smooth operation of the screw shaft and the engaging piece. I was able to configure it. In particular, in the present invention, since slight vibration of the spool or the like is suppressed when the handle is operated, there is an effect that the feeling during operation is improved.
