CLUTCH CONTROL DEVICE IN VEHICLE POWER UNIT

PROBLEM TO BE SOLVED: To enhance responsiveness by reducing an influence of an outside air temperature so that the hydraulic control of a clutch is performed in a position near the clutch, in a vehicle power unit having a pair of hydraulic clutches which are interposed in the middle of a power transmission system between a crank shaft of an internal combustion engine and drive wheels so as to switch the connection and disconnection of power transmission according to an oil pressure change in a hydraulic chamber.SOLUTION: A solenoid body is attached to an external peripheral side of a clutch cover 46 which covers a pair of hydraulic clutches, and is attached to a machine main body. An oil pressure controlling solenoid valve 98 for controlling the pressure of working oil from an oil pump, a single changeover valve 89 which selectively switches the working oil from the oil pressure controlling solenoid valve 98, and supplies it to a hydraulic chamber of a pair of the hydraulic clutches, and a shift solenoid valve 100 for controlling the operation of the changeover valve 89 are attached to the solenoid body.
