Claims

[Scope of utility model registration request]

A drive V pulley, which has a fixed face that does not move in the axial direction and a movable face that is pressed toward the fixed face by centrifugal force, is mounted on the crankshaft.
Similarly, a driven V-pulley, which has a fixed face that is immovable in the axial direction and a movable face that is pressed toward the fixed face by a spring, is mounted on the driven shaft to form a V-belt automatic transmission. In a transmission device for a motorcycle that transmits the torque of a driven V-pulley to a driven shaft via a centrifugal shoe-type starting clutch arranged in parallel above, a tubular driven pulley shaft is rotatably supported on the driven shaft. Be prepared,
A centrifugal shoe-type starting clutch is constituted by a clutch housing fixed to the outer end of the driven shaft, and a drive plate fixed to the outer end of the driven pulley shaft opposite to the clutch housing and provided with a centrifugal shoe. A driven V pulley fixed face is fixedly provided on the inside, and a movable face facing the inside of the fixed face is driven by a boss portion whose outer end passes through the inner hole of the fixed face and extends to the outer end of the driven pulley shaft. The pulley is rotatably supported on the pulley shaft so as to be slidable in the axial direction, and an elastic spring is elastically mounted between the outer end of the boss and the outer side of the fixed face, and the inner hole of both ends of the boss is connected to the driven pulley shaft. A transmission device for a two-wheeled motor vehicle, characterized in that a sealing member is interposed between the transmission devices.
