Abstract
A moving core of a solenoid air valve has a flange portion arranged on a side of a fixed core, provided in a radially projecting manner and having a first diameter, and a shaft portion having a second diameter smaller than the first diameter. Therefore, a sufficient area of magnetic pole is ensured around a rubber packing in the flange portion of the moving core. Consequently, the solenoid air valve structured such that an area of magnetic pole is sufficiently ensured even if the moving core is made thinner in order to ensure a volume of a coil body in reducing the solenoid air valve in size can be provided.
