Abstract: PURPOSE:To improve the extent of operability by energizing a clutch lever, a tension pulley or the like in the on-direction at a time when the clutch lever is operated to the on-side, and those of lever, pulley or the like in the off- direction when operating it to the off-side, respectively. CONSTITUTION:When a clutch lever 19 is operated to the clutch on-side, a longitudinal shaft 37 is rotated counterclockwise, and a lonk arm 36 is also rotated in the same direction via a link arm 38 and a connecting rod 39. Accordingly a tension pulley 32 is pressed to a V belt 30 under pressure, making it into clutch engagement. At this time, since a coil spring 35 is shifted to the more inside than the longitudinal shaft 37, the tension pulley 32 is energized toward the V-belt 30, and the clutch lever 19 to the on-side, respectively. When the clutch lever 19 is turned round to the rear, the longitudinal shaft 37 is rotated clockwise, and the tension pulley 32 separates from the V-velt 30, making it into clutch disengagement. At this time the coil spring 35 energizes the tension pulley 32 in a separating direction from the V-belt 30.
