<p>PURPOSE: To provide the structure of an oil pressure circuit by which air stored, for example, in a hose which allows a clutch cylinder to communicate with a clutch oil tank respectively equipped on a motor truck, etc., can be easily and assuredly bled in a short time. CONSTITUTION: The structure of an oil pressure circuit is equipped with the clutch cylinder 4 (piston cylinder mechanism) of a truck to feed operating oil 6 to a hydraulic actuator, a clutch oil tank 3 (oil tank) which is arranged in the approximately same position as this clutch cylinder 4 in a vertical direction and stores the operating oil 6 supplied to the clutch cylinder 4, and a hose 5 (oil passage) through which the clutch oil tank 3 and the clutch cylinder 4 communicate with each other. A sub-tank 11 in which a chamber whose inner part is opened to the atmosphere as well as to communicate with the hose 5 is formed, is arranged in the upper part of the hose 5, so that air can be discharged in the atmosphere through the chamber.</p> |
