Abstract
In the region in which a coil and a connector are provided, the leakage of a fluid to which coil and connector is prevented by a seal member, a passage extending from the seal member to a position in the vicinity of a terminal of the connector is formed. At the time of completion of the production of a solenoid valve assembly, an air-tightness test on the seal member can be conducted directly through the passage, so that the detection of damage to the seal member, the detection of bite into the seal member, the detection of a defect of the seal member and so on can be carried out at the time of completion of the production of the mentioned assembly. Namely, the detection of the sealability of the seal member is rendered possible.
