A guide portion slidably receiving a movable core is constructed by a large-diameter portion, a middle-diameter portion, a first small-diameter portion, a magnetism blocking portion, and a second small-diameter portion. A ring portion, which has an outer diameter greater than that of a coil assembly provided radially outside of the guide portion, is provided radially outside of the middle-diameter portion. When the guide portion attached with the coil assembly is attached to a support member corresponding to a mating member, the guide portion is attached to the support member by applying a rotational torque of to the ring portion in an axial direction of the guide portion according to a tool without an interference between the tool and the coil assembly. Therefore, an electromagnetic valve device for a gaseous fuel can be readily attached to the support member. |
