A solenoid valve device having high reliability, reduced in size, and simplified in structure, wherein an electric power is led to a coil (17), and a valve element (16) is displaceably driven by a magnetic action to adjust the opening of a valve passage (43). The electric power for driving the valve element (16) is led to the coil (17) through a conductive wire body (18). The conductive wire body (18) is installed in the housing (15) starting at the portion thereof exposed from a tank (11) to the portion thereof where the coil (17) is installed, and held on the housing (15) in the inserted state in the housing (15). Since the conductive wire body (18) is installed through the housing (15) and held on the housing (15), it is protected against vibration and impact applied from the outer side thereto. Accordingly, the reliability of the conductive wire body (18) against vibration resistance and impact resistance can be increased. Also, the conductive wire body (18) can be neatly stored in the housing (15) by storing it in the housing (18).

L~invention concerne un dispositif à électrovanne offrant une grande fiabilité, des dimensions réduites et une structure simplifiée, comprenant une alimentation électrique raccordée à une bobine (17) et un élément de vanne (16) déplacé par effet magnétique pour régler l~ouverture d~un passage de vanne (43). L~alimentation entraînant l~élément de vanne (16) est raccordée à la bobine (17) par un corps en fil conducteur (18). Le corps en fil conducteur (18) est installé dans un carter (15) au départ de la partie de celui-ci sortant d~un réservoir (11) jusqu~à la partie de celui-ci où la bobine (17) est installée, et maintenu sur le carter (15) dans l~état inséré dans le carter (15). Comme le corps en fil conducteur (18) est installé à travers le carter (15) et qu~il est maintenu sur le carter (15), il est protégé des vibrations et des chocs s~exerçant de l~extérieur. L~invention permet donc d~améliorer la résistance du corps en fil conducteur (18) aux vibrations et aux chocs. Il est en outre possible de ranger soigneusement le corps en fil conducteur (18) dans le carter (15).
