PROBLEM TO BE SOLVED: To reduce size and a cost by a method wherein a coupled part between a valve body and a solenoid housing is transferred in the valve body and forms coupling structure by means of no bolt. SOLUTION: An annular solenoid housing 38 with a built-in solenoid 37 is arranged in a fit-in state in the cup part 32a of a valve body 32, and by pressing the front end of the solenoid housing 38 through the force of a return spring 45, a flange part 41 arranged at the outer periphery thereof is brought into abutment against a stepped part 44 formed at the valve body 32. Further, a cylindrical part 46 extending from the rear end of the solenoid housing 38 to the rear is fitted in an annular protrusion 47a formed on the cup part 32a of the valve body 32 and with this state, a protrusion part 50 formed on the valve body 32 is fitted in a recessed part formed in the tip of the cylinder part 46, and this uneven fit-in part is used as a detent for the solenoid housing 38. Further, a U-shaped key member 52 inserted in the valve body 32 from a radial direction is fitted in the peripheral direction groove 51 of the cylinder part 46, and the key member is used as pull-off protection for the solenoid housing 38. |
