A solenoid valve includes a tubular coil bobbinhaving a coilwound around the outer peripheral surface thereof, a corearranged inside the coil bobbin, a yokefor fixing the core, a plungerhaving a central axis coaxial to that of the coreand being movable in the axial direction, and a valve housinghaving ports, wherein the yokeis provided, in the outer surface thereof, with a fitting holeprojecting tubularly for receiving and fixing the coreinserted therein and securing it in place, and the coreis provided with a projectionto be inserted into the fitting holeand a flangeto abut against the inner surface of the yoke

A fuel-evaporated gas processing system includes an input port taking in evaporated gas evaporated in a fuel tank; output ports supplying the evaporated gas taken in through the input port to an intake system of an engine; a chamber interposed between the input port and the output ports; an electromagnetic valve device including at least first and second electromagnetic valves disposed in the connection between the input port or the output ports and the chamber, either of the input port or the output ports being branched off into a plurality of sections, and perform opening and closing operations in response to a driving signal; and a valve control means driving the first and the second electromagnetic valves of the electromagnetic valve device.

A valvefixed on a tipof a rodas a moving part, abuts a sealing partof a fluid passagewhen the rodmoved to the left, and interrupts a flow of fluid, is made, for instance, of elastic materials such as rubber. This absorbs an impact generated when the valve is sealed (at the time of collision), and reduces loudness of an actuating sound caused by a collision between the valveand the sealing part

A center core laminated part and a side core laminated part are formed separately from each other. The center core laminated part is integrated with the side core laminated part by engaging depressed engaging portions with projected engaging portions, wherein the depressed engaging portions and the projected engaging portions are formed relatively on the corresponding opposite surfaces, to form a laminated core part for forming a magnetic path.
