As the output rotation shaft rotates in a predetermined direction, the first input gear is also rotated in a predetermined direction. However, when the first and second handle rods oscillate in the pushing direction, the first input gear rotates in the opposite direction to the rotation direction of the pivot shaft of the first handle rod, so that the first input The connection state between the gear and the swing shaft of the first handle bar is disconnected through the first clutch.

  As described above, even if the swinging direction of the first and second handle rods is switched between the pulling direction and the pushing direction by the rotation transmission operation and the rotation cutting operation by the first and second clutches, the first and second The input gear and the output gear (including the gear system when a gear system is provided between the first input gear and the output gear, and the gear system when the gear system is provided between the second input gear and the output gear) are included. It is rotated in a predetermined direction, and the output rotation shaft is continuously rotated in the same direction.

The output rotation shaft, which is the rotation shaft of the first output gear, is rotated in a predetermined direction.

  Here, since the output rotation shaft is also the rotation shaft of the second output gear, the rotation of the second output gear is transmitted to the second input gear directly or via the gear system. As the second input gear rotates in one direction, the second input gear is also rotated in a predetermined one direction. However, when the first and second handle rods swing in the pulling direction, the rotation direction of the second input gear and the rotation direction of the swing shaft of the second handle rod are opposite to each other. The connection state between the first handle bar and the swing shaft of the second handle bar is disconnected via the second clutch.

  On the other hand, when the handle grip is grasped and the first and second handle rods are integrally swung in the pushing direction, the rotation of the swing shaft of the second handle rod is caused through the second clutch. The second input gear is rotated in a predetermined direction in the same manner as when the first and second handle rods are pulled by being transmitted to the two-input gear. The rotation of the second input gear is transmitted to the second output gear directly or via a gear system, and the second output gear is rotated in a predetermined direction to output the rotation shaft of the second output gear.

  Therefore, the rotation direction of the first input gear 4 (clockwise in FIG. 4) and the rotation direction of the swing shaft 6a1 of the first handle collar 6a (counterclockwise in FIG. 4) are opposite to each other. Since the first input gear 4 and the swing shaft 6a1 of the first handle collar 6a are disconnected through the one clutch 7, the swinging motion of the first handle collar 6a in the pushing direction is the first input gear. The rotation of 4 is not hindered.

In the direction, since the second input gear 27 and the swing shaft 28b1 of the second handle collar 28b are disconnected via the second clutch 30, the second handle collar 28b swings in the pulling direction. Does not hinder the rotation of the second input gear 27.

On the other hand, when the second handle collar 28b is pivoted in the pushing direction (solid arrow (rightward in FIG. 8B )), the rotation of the swing shaft 28b1 of the second handle collar 28b ( FIG. 8 ) . (B) counterclockwise) is transmitted to the second input gear 27 via the second clutch 30. Then, the second input gear 27 is rotated in a predetermined direction (counterclockwise in FIG. 8B), and the second output gear 24 meshed with the second input gear 27 is also in a predetermined direction ( FIG. 8B). is rotated in the clockwise direction), the output rotary shaft 22 together with the second output gear 24 is rotated in a predetermined direction clockwise direction (FIG. 8 (a) and Figure 8 (b)).

Here, the predetermined direction (FIGS. 8 (a) and 8 (b) clockwise) with the rotation of the first output gear 23 is also driven to a predetermined direction together the output rotary shaft 22 (FIG. 8 (A) (clockwise in FIG. 8A ), and in conjunction with this, the intermediate gear 25 meshed with the first output gear 23 is rotated in a predetermined direction (counterclockwise in FIG. 8 (a)) . The first input gear 26 meshed with the gear 25 is rotated in a predetermined direction (clockwise in FIG. 8A ) . In this case, the first handle collar 28a is pushed in the pushing direction (dotted arrow in FIG. 8 ) . (To the right)).

For this reason, the rotation direction of the first input gear 26 (the clockwise direction in FIG. 8A ) and the rotation direction of the swing shaft 28a1 of the first handle collar 28a (the counterclockwise direction in FIG. 8A ) are reversed. The first input gear 26 and the swing shaft 28a1 of the first handle collar 28a are disconnected via the first clutch 29, so that the first handle collar 28a swings in the pushing direction. The operation does not hinder the rotation of the first input gear 26.

As shown in FIG. 9 , even if the swinging direction of the first and second handle collars 28a, 28b of the operation handle 28 is switched from one of the pulling direction and the pushing direction to the other, each gear 23, 24, 25 , 26, 27 always rotate in a constant direction, and the output rotation shaft 22 can be continuously rotated in a constant direction ( clockwise in FIG. 8 ).

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

For example, in the present embodiment, a description has been given using a fishing reel as a specific example of the manual rotary instrument 1 , 20 , but this specific example is not necessarily limited to this, and a manual rotary tool, for example, The rotary instrument 1 of the first embodiment may be applied to a drill tool or the like, and the rotary instrument 20 of the second embodiment may be applied to a manually wound winch or the like.

Further, the first gear train between the first input gear 4 and the output gear 3 in the examples and the second input gear 5 and gear train between the output gear 3, the first input gear 26 in the second embodiment and the intermediate gear 25 The gear system of the first output gear 23 and the gear system of the second input gear 27 and the second output gear 24 form a gearbox by the cooperation of any of the meshed gears. there were.

  However, these gear systems are not necessarily limited to the speed increaser, and may be speed reducers. For example, when the rotating device is applied to a hand-wound winch or the like, it is preferable to use the gear system as a speed reducer in order to reduce a load during winding.
