Abstract: Provided is a lid device, which is compact and can be installed in an efficient manner. The lid device (20) releasably locks a lid (10) provided with a hinge (12) in a closed position. The lid device is provided with a push lifter (32) that alternates between an extended state and a retracted state each time the lid is pushed, a motor (46) placed next to the push lifter, a lock member (18) and a transmission mechanism (64) for transmitting the output of the motor. The lock member and the transmission mechanism are positioned between the push lifter and a side profile of the drive unit remote from the push lifter, and the lock member is moveable in a direction substantially perpendicular to a lengthwise direction of the push lifter and a direction from the push lifter toward the drive unit.

Abstract: A lid attachment member includes: a metal plate that is equipped with an attachment hole to which a lid of a container is to be attached; a raised or recessed seal portion that is formed at, and continuously all the way around, an outer peripheral portion of the metal plate; and a resin member that is integrally formed on the outer peripheral portion of the metal plate, covers the seal portion, and has a back surface side that is configured to be welded to an open portion of the container.

The lid device is provided with a push lifter that alternates between an extended state and a retracted state each time the lid is pushed, a motor (54) placed next to the push lifter, a lock member (18) and a transmission mechanism (60, 64) for transmitting the output of the motor. The push lifter and the motor are arranged such that a lengthwise direction of the push lifter and a lengthwise direction of the motor are perpendicular to each other, and such that the motor at least partly overlaps with the push lifter when seen from the lengthwise direction of the motor.

Abstract: In a lid device opening and closing a fuel lid of a vehicle by a push-push mechanism, a common push lifter can be applied in both cases with and without a mechanism for locking the fuel lid at a closed position. The lid device (20) indirectly locks the fuel lid (10) at the closed position by controlling a displacement of a push rod (22) protruding and retracting from a push lifter unit (24). In order to control the displacement of the push rod (22), an engagement member (56) engaging the push rod (22) is movably supported in a housing (54) of a drive unit (26), and the push lifter (24) and the drive unit (26) are formed as separate members.

Abstract: A fuel cell system of the present invention includes a fuel cell stack, a fuel system for supplying a fuel gas to the fuel cell stack, and on-off valves which form a closed space not including the fuel cell stack in the fuel system. The closed space is filled with an inspection gas from the on-off valve which functions also as an inspection gas inlet port. After completion of the inspection, the inspection gas in the closed space is discharged from the on-off valve which functions also as an inspection gas outlet port.
