Is stopped at the original position by contacting the setting section (41) of the position setting body (4). Then, as shown in FIG. 1, the thumb (U) of the hand gripping the grip (11) is brought into contact with the operating portion (21) of the operating lever (2) stopped at the original position, and the state shown in FIG. When moving forward from the front to the counterclockwise position, the transmission (24)
Engages with one of the passive parts (75) of the positioning body (72), and the operating force of the operating lever (2) is transmitted to the winding body (6) via the positioning body (72), and this winding body (6) moves forward in the counterclockwise direction, pulls the operation wire, and when the rotation of the lever (2) in the forward movement direction reaches a stroke of one pitch of the engaging portion (71), the gear shifts one step. If the thumb reaches a two-pitch stroke, two-step shifting can be performed. Up to three-step shifting can be performed one step at a time by one operation of the thumb, or a plurality of steps at once. is there. The four or more gears can be shifted step by step by returning the operating lever (2) to the original position and then re-moving the operating lever (2) from the original position to the forward position. Thus, the gears can be changed at once in a plurality of gears. In a state where the gear is shifted to a desired low speed, the engaging body (73) engages with a desired engaging portion (71) as shown in FIG. 6, and the winding body (6) is rotated in the backward movement direction. Therefore, it is possible to reliably maintain the shift state in which the gear is shifted to the low-speed side gear stage.

Next, in order to shift from the state shown in FIG. 6 in which the gear has been shifted to the lower gear to the higher gear, the operating portion (21) of the operating lever (2) in the original position is pushed downward, and the operation is performed. The control lever (81) provided integrally with the part is moved upward from the lower position, and the forward movement causes the control lever (81) to move forward.
The control part (82) provided in the contact part (77) of the pressing spring (74)
, The pressing spring (74) is elastically deformed in the axial direction of the support shaft (31). The elastic deformation of the pressing spring (74) releases the urging of the engaging body (73), and the winding is performed. The body (6)
It moves backward by a predetermined amount by the force of the return spring (62). At this time, the restricting portion (83) of the control lever (81) comes into contact with one restricting piece (76) of the positioning body (72) to restrict the amount of rewinding of the winding body (6) by the return spring (62). When the operation of the operation section (21) is released, the operation section (21) is moved back by the force of the return spring (28), and the operation section (21) is in contact with the restriction piece (76) of the restriction section (83). When the engagement is released and the pressing spring (74) is elastically restored, the engaging body (73) is urged toward the engaging portion (71), and the engaging body (73) is moved toward the engaging portion (71). The winding body (6) moves back together with the positioning body (72) by the force of the return spring (62) before engaging with the positioning body (72). The engaging portion (71) engages with the engaging portion (71), and this engagement prevents the return movement of the winding body (6) by the return spring (62), so that the speed change state in which the gear is shifted to the high-speed stage is reliably achieved. When the engaging body (73) engages with the engaging portion (71), the load acting on the control lever (81) is suddenly reduced by the elasticity of the pressing spring (74). Therefore, a click feeling can be given to the hands operating the operation unit (21). Further, the returned operation unit (21) comes into contact with the lower surface of the base (22) and stops at the original position as shown in FIG.
Prepare for the next operation. Then, when the operation portion (21) stopped at the original position is newly pushed downward, the engagement of the engagement body (73) with the engagement portion (71) is released, and the winding is performed. The body (6) is moved back by the force of the return spring (62), so that the wire can be further relaxed and the speed can be further shifted to the higher-speed side by one step.
Can be urged by the pressing spring (74) to engage with the adjacent low-speed side engaging portion (71) to hold the rewinding position of the winding body (6). The shift from the low-speed stage to the high-speed stage is performed by engaging the restricting portion (83) of the control lever (81) with the restricting piece (76) for each pitch of the engaging portion (71). Since the amount of backward movement of 6) is regulated, the control lever (81) needs to be operated forward a number of times corresponding to the gear position. However, the control piece (76) is eliminated and the control lever (81) is removed.
The amount of engagement of the engagement body (73) with the engagement portion (71) is controlled by adjusting the operation, and the take-up body (6) is rotated one by one or a plurality of stages at a time to change gears. It may be.
