ABSTRACT:
A device which can easily adjust a relationship between a clutch pressure of an input clutch and a braking force (brake pressure) generated by a brake device to a desired relationship by a simple structure, in which a draining oil passage which is branched from an oil passage for supplying a pressure oil to the input clutch is provided, and the draining oil passage is communicated with a tank. The draining oil passage is provided with a pressure reducing valve which increases the pressure oil flowing through the draining oil passage depending on the valve position to decrease a clutch pressure of the input clutch. A brake operating member is mechanically coupled with a valve operating member of the pressure reducing valve, and the valve operating member of the pressure reducing valve is mechanically coupled with a valve operating member of the brake control valve by, for example, a spring.
