Electromagnetic pressure reducing valve and fluid pressure control device including electromagnetic pressure reducing valve

An electromagnetic pressure reducing valve configured to reduce a pressure of a working fluid flowing in through an inlet passage and flowing out through an outlet passage to a predetermined pressure, comprising:

• a valve body configured to allow or to shut off communication between the inlet passage and the outlet passage;
• and
• a solenoid configured to give a thrust according to an intensity of a supplied electric current to the valve body, wherein
• the valve body has a pressure receiving surface configured to generate a thrust in a direction opposite to the thrust by the solenoid by action of a pressure of the outlet passage;
• and
• an area of the pressure receiving surface is set smaller than a cross sectional area of the valve body.
