Abstract

PURPOSE:To improve the relieving performance and improve the security feeling and safety of the travel operation by forming a relief pressure adjusting piston with the same diameter over nearly the whole length and providing a portion with a diameter larger than that of a piston sliding section on the inner periphery wall of a cylinder chamber to form an orifice section. CONSTITUTION:A relief pressure adjusting piston 2 with the same diameter over nearly the whole length of the outer periphery wall 2A is formed, and a portion 8B with a diameter larger than that of the sliding section 8A ot the piston 2 is provided on part of an oil chamber O4 storing it to form an orifice section 9 of the oil flow from the third oil path R3 to the oil chamber O4. The relieving performance is thereby improved with the simple processing, a vehicle is started smoothly with no shock, and the security feeling and safety in the vehicle travel operation can be improved.
