PURPOSE:To prevent the load in the vertical direction from concentrating on the insulating plate in such a way that vertical external force of a solenoid valve is restricted from moving in the counterdirection in the vertical directions by means of the tangential contact to the horizontal through an O-ring. CONSTITUTION:An insulating plate 5 is tightly fixed in the tangential contact on the outer bottom side of a choke chamber 1 in the condition that the diametral contracting part 23 is formed on the upper end side of an inserting hole 20 of a choke chamber 1 to the outer peripheral part 19 at the upper part of an solenoid valve 3, and the upward displacement is engaged in the tangential contact of the tip on the rim of the outer cylindrical part 19 at the diametral contracting part. The horizontal of the stepped part 21 which is formed at one part of the upward inner bottom side of a float chamber 2, and the end side of the outer peripheral stepped part 24 of an outer cylindrical part 14 are tangentially contacted together through a resilient O-ring 25 at the lower part of the solenoid valve 3. The solenoid valve 3 can be entirely prevented from concentrating the load in the vertical directions to the insulating plate 5, because the movement in the mutual counterdirections to the vertical directions is restricted by the tangential contact at the horizontal to the upper end of the rim of the outer cylindrical part, and the diametral contacting part 23 of an inserting hole 20. |
