Abstract
According to a solenoid air valve, a flange portion of a moving core and a flange portion area of a bobbin implement a stop area defining a distance of travel of the moving core in a direction away from a fixed core. An end portion of a shaft portion of the moving core can project outward through an opening of a frame cover, so that a gap between a surface of the frame cover facing the shaft portion and a side surface of the shaft portion (distance: L) can be minimized. Consequently, a solenoid air valve having a structure allowing improvement in magnetic efficiency by making smaller the gap between the frame and the moving core is provided.
