Abstract:
A pressure regulating valve (22) is disposed to be accommodated in a case member (30). The case member (30) comprises an accommodation part (36). A side surface portion (42) of the accommodation part (36) is formed as an elastically deformable portion (43) which can elastically deform outward in a radial direction. A retaining structure (86) for the pressure regulating valve (22) is formed in an end section on the input side of the elastically deformable portion (43) into which the pressure regulating valve (22) is inserted. The retaining structure (86) comprises: an engagement piece (88) set on a lower end section of the elastically deformable portion (43); and an engagement part (90) set on a lower end section of a housing (46). In addition, the engagement piece (88) comprises a protrusion piece (92) which forms a fitting recess section (94) that is fitted to the engagement part (90) on the lower end section of the housing (46), and is configured to prevent the elastically deformable portion (43) from being displaced outward in a radial direction.
