ABSTRACT:
A pressure controlling device for vehicle comprising a control unit having a plurality of electromagnetic portions, an electronic circuit portion provided in a housing and a conductive connecting member for electrically connecting these, an actuator unit having a plurality of valve bodies and a network of pressure path, wherein the plurality of valve bodies are protruded so as to be inserted in the plurality of electromagnetic coil portions in the control unit respectively; and the electromagnetic coil portions are formed by a bobbin with coil, an upper yoke and a lower yoke for fabricating a magnetic path and an elastic object provided between the lower yoke and the bobbin and a means for contacting the bobbin to a part of the housing in order to restrict movement of the bobbin, whereby a stress applied to an electrically connecting portion in the electromagnetic portions caused by engagement and separation between the control unit portion and the actuator unit can be relaxed.
