Abstract
In a solenoid valve device, a valving element opens and closes a fluid passage by exerting an electromagnetic force between an armature and a core. The solenoid valve device includes a movable portion which includes the armature and the valving element. A fixed portion includes the core. An impact absorbing unit absorbs an impact of the movable portion on the fixed portion, the impact absorbing unit including a gel part which transforms a mechanical energy of the impact into a thermal energy.
