PROBLEM TO BE SOLVED: To decrease the wall thickness of a housing.SOLUTION: A seal portion 90 is formed, which separates a first conduit D and a second conduit B by abutting between an outer peripheral surface of a pressure-adjusting valve 8A and an inner wall surface of a housing 40. A conduit 43 on a side connected to a reservoir chamber 44 of the second conduit B is formed by the outer peripheral surface on the reservoir chamber 44 side rather than the seal portion 90 of the outer peripheral surface of the pressure-adjusting valve 8A and the inner wall surface of the housing 40, thereby disposing the conduit B close to the pressure-adjusting valve 8A while preventing the conduit 43 and the seal portion 90 from being superimposed in a diametrical direction of the pressure-adjusting valve 8A.
【課題】ハウジングの肉厚を小さくする。【解決手段】調圧弁8Aの外周面とハウジング40の内壁面との当接により第1管路Dと第2管路Bを分離するシール部90を形成する。そして、第2管路Bのうちリザーバ室44に接続される側の管路43を、調圧弁8Aの外周面のうちシール部90よりもリザーバ室44側の外周面とハウジング40の内壁面とによって形成することにより、管路43とシール部90が調圧弁8Aの径方向に重ならないようにして、管路Bを調圧弁8Aに近づけて配置する。【選択図】図3
