PURPOSE:To eliminate the imbalance of energizing force in a spring, by fitting a holding member slidably in a contact member making contact with a valve piston, while constituting an energizing mechanism in a way interposing the spring between both these members, and holding this energizing mechanism free of rocking motion. CONSTITUTION:A support rod 34 is secured tight to a cap 31 of a hydraulic control unit, and a holding member 38 is rockably held by this support rod 34. A contact member 43 is slidably but unrockably fitted in this holding member 38, while a spring 45 is interposed between both these members 38 and 43. The holding member 38 is made to come into contact with each of valve pistons 23R and 23L of each P valve. |
