Abstract
In a power transmission apparatus for a vehicle having a hydraulic pressure type clutch capable of switching to transmit and cut power between a crankshaft of an engine and driving wheels and a clutch control valve for controlling hydraulic pressure provided to the clutch, the operational characteristic of the hydraulic pressure clutch is made variable and an adjuster mechanism for compensating for a wear amount of clutch plates is dispensed with. A clutch control valve includes a valve housing having an input port connected to a hydraulic pump and an output port connected to a clutch. A spool is capable of switching to communicate and cut the input port and the output port and is slidably fitted in the valve housing. Furthermore, a linear solenoid is coaxially connected to the spool and is capable of controlling output hydraulic pressure from the output port to a value in accordance with input current of the linear solenoid.
