<P>PROBLEM TO BE SOLVED: To attain a structure preventing gross slip from occurring in a traction section 16 due to oil pressure shortage in respective oil pressure chambers of an actuator 11 and a pressing device 13a when starting an engine. <P>SOLUTION: A flow control valve 35 is provided in an upstream side portion of a lubrication oil supply path 22. When the engine is started from a stop state, a ratio sent to the lubrication oil supply path 22 in the traction oil discharged from an oil sending pump 15 is limited by using the flow control valve 35. With this, when starting the engine, the oil pressure in the respective oil pressure chambers of the actuator 11 and the pressing device 13a are raised quickly. <P>COPYRIGHT: (C)2013,JPO&INPIT |
