PROBLEM TO BE SOLVED: To reduce the size of a body by decreasing a displacement amount (lift amount) of a valve body in a relief valve.SOLUTION: A relief valve 46 has a cylindrical protrusion 102 which constitutes a hydraulic control device integrally with a body as a body part. An output passage 96 is formed at the body along the thickness direction of the body, and the relief valve 46 is arranged above the output passage. In the relief valve 46, a guide part 106 is arranged at a downstream side of a valve seat 52, and a relief hole 108 as a lateral hole is formed between the valve seat 52 and the guide part 106. |
