PURPOSE:To prevent the occurrence of hunting by throttling the inside diameter of a pressurized oil path near the other end of a cylinder enough to damp pulsation or pressurized oil. CONSTITUTION:Pressurized oil paths 42, 43 are disposed side by side extending from a pressurized oil path 41 connecting pressurized oil paths 31, 35 to the pressurized oil path 35. The pressurized oil path 42 is provided with an orifice 44 having an inside diameter of 0.8mm. and the pressurized oil path 43 with an orifice 45 having an inside diameter of 1.1mm.. In this arrangement, pulsation is prevented from being transmitting from the pressurized oil path 31 to the pressurized oil path 35 to prevent the occurrence of hunting. |
