A bobbin 7 around which a solenoid 6 is wound is connected to an electronic control unit 1 fixed to a base plate portion 3c through a connection terminal 11 penetrating a connection hole 2 and a guide hole 4 whose one end portion is fixed to a bobbin 7 and is connected to an end portion of a solenoid 6 and other end portion is connected to the connection hole 2, a hook portion 3d is engaged into a hole 10b so that a yoke 8 is supported, an electromagnetic-force generating portion 5 is assembled to a casing 3, gaps 18 and 21 are formed between the yoke 8 and the bobbin 7 so that the yoke 8 is made to be movable with respect to the bobbin 7 in the axial direction of the sleeve 13 and also in a direction perpendicular to the axial direction of the sleeve 13. When the casing 3 and the valve housing 14 are assembled, the sleeve 13 is smoothly inserted into the electromagnetic-force generating portion 5, and the yoke 8 is pressed and urged to the valve housing 14 by a ring spring 12.

Pressure control apparatus

In an electromagnetic valve device, in order to secure a core assembly to a housing, an annular spacer is used. The annular spacer is fitted between a conical inner surface of a receiving portion of the housing and a conical opening of a casing. Since the conical opening of the casing is mounted on a tapered surface of a stationary core accommodated in the receiving portion of the housing, the core assembly is secured to the housing.
