<p>PURPOSE:To permit a clutch to easily obtain its neutral condition, by using a stopper restricting the movement of a centrifugal clutch piston and preventing it from being forced to be brought into contact with a clutch plate. CONSTITUTION:If an input shaft 1 is rotated in a condition that pressure oil is not introduced into a pressure oil chamber 12, a clutch, placing an oil hydraulic piston 11 to be positioned in the right end part, presses a centrifugal clutch piston 15 leftward by a centrifugal load of a weight 14. However, the clutch, adapting the centrifugal clutch piston 15 to a stopper 17 and restricting a movement of the piston 15 to the leftward, prevents a protruding part 15b of a centrifugal clutch piston 15 from being brought into constact with clutch plates 9, 10. Accordingly, a neutral condition can be easily maintained.</p> |
