This embodiment is constructed as described above, and when both levers (17) and (22) are in the off position as shown by the solid line in FIG. 1, the on lever (22) is turned on in the direction of the broken line in the figure. At this time, the operating force of the on-lever (22) is transmitted to the main clutch lever (17) via the lever arm (32), the rotating body (31), the shaft (30) and the clutch arm (26). When the main clutch lever (17) operates, the axial distance (l) between the support shaft (24) and the shaft (30) is constant, and the operating length of the on-lever (22) is equal to that of the rotating body (31). The distance (L) between the contact portion of the lever arm (32) and the support shaft (33) is sequentially increased as the lever arm (32) swings upward about the support shaft (33). Let it be small. Therefore, if the operating force at the time of turning on the main clutch lever (17) is constant, the operating force of the on-lever (22) can be proportionally reduced by the reduction of the distance (L). As shown in FIG. 4, when the operation force of the main clutch lever (17) that maximizes the tensile force of the wire (29) near the fulcrum of the link (28) is required, the distance (L) is set to By making the minimum, the on lever (22)
The operating force of the on-lever (22) can be reduced, that is, when the main clutch lever (17) exceeds the fulcrum, the on-lever (22) becomes smaller as the distance (L) of the on-lever (22) becomes smaller than the off-position. ) Can reduce the operating force.
