PURPOSE:To stably move a device by coaxially connecting a driving side first intermediate rotating shaft to a driving rotating shaft through a first clutch, and coaxially connecting a driving side second intermediate shaft to this shaft through a second clutch. CONSTITUTION:A driving rotating shaft 2 is connected to a coaxially disposed driving side first intermediate rotating shaft 12 through a dog clutch 10 (first clutch), and the clutch 10 conducts connection and disconnection by axially moving a movable dog on the shaft 12 side by a hydraulic driving mechanism C1. The shaft 12 is connected to a coaxially disposed driving side second intermediate rotating shaft 16 through a hydraulic multiple disc clutch 14, and connected and disconnected by a hydraulic driving mechanism C2. A driven shaft 4 is connected to a coaxially disposed driven side intermediate rotating shaft 22 through a differential mechanism 20. A chain 28 is laid over the shaft 12 and the differential case of the differential mechanism 20, and the shaft 16 is connected to the shaft 22 by a V-belt 32. The operations of the clutches 10, 14 and the operation of the V-belt type non-stage transmission mechanism are properly controlled to make wide transmission ratios. |
