Abstract: In an in-tank valve, a detector including a detecting sensor is disposed on an end of a body, and the detecting sensor is accommodated inside a sensor housing. Within the sensor housing, a sensor retaining member is formed in an interior part of an opened sensor accommodating section, and the detecting sensor is disposed therein so as to face toward a first communication hole of the sensor retaining member. Lead wires, which are connected to the detecting sensor, are led out to the exterior in a bending fashion from a wiring port, whereby entry of hydrogen gas to the side of the detecting sensor is prevented by suitably closing the wiring port.

Abstract: In a detector that constitutes an in-tank valve, an attachment part formed on one end thereof is arranged in facing relation to a connector of a drive unit, and arm members of a bracket, which is substantially U-shaped in cross section and is fixed to the connector, are inserted in and engaged with engagement holes of the attachment part. Thus, the detector is always retained firmly in a state of being pulled to the side of the drive unit by elastic forces of the bracket.

Abstract: A solenoid valve includes first and second attraction portions in the interior of a housing disposed on an upper part of a valve body. A movable iron core, which confronts the first and second attraction portions, is disposed displaceably in the housing. Further, in the interior of the first attraction portion, which is recessed in a concave shape, a first guide body is installed, the first guide body being formed in a cylindrical shape from a non-magnetic material, and a first rod member of the movable iron core is supported displaceably in axial directions by the first guide body. On the other hand, a cylindrically shaped second guide body is disposed on a lower end of the housing, and a second rod member of the movable iron core is supported displaceably in the axial directions by the second guide body.
