摘要： PROBLEM TO BE SOLVED: To easily adjust a relationship between clutch pressure of an input clutch and braking force (brake pressure) generated by a brake device to a desired relationship, by a simple structure. SOLUTION: A device which can easily adjust the relationship between the clutch pressure of the input clutch and the braking force (the brake pressure) generated by the brake device to the desired relationship by the simple structure is provided with a draining oil passage which is branched from an oil passage for supplying pressure oil to the input clutch, 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 reduce the clutch pressure of the input clutch. A brake operating means is mechanically coupled with a valve operating member (spool) of the pressure reducing valve, and the valve operating member of the pressure reducing valve is mechanically coupled with a valve operating member (spool) of a brake control valve by, for example, a spring.
