<P>PROBLEM TO BE SOLVED: To reduce cost by reducing the number of component items even when a gas passage part on the downstream side of a solenoid valve is formed to extend straightly upward from a valve hole 64 of the solenoid valve and bend in an L-shaped form, in a gas valve device including a valve casing 2 with a manual valve 4 incorporated therein, a passage block 5 having a flange part 51 jointed to a flange part 21 with a gas outflow port 23 on an outer surface of the valve casing opened, and a solenoid valve 6 for opening/blocking a gas passage 52 in the passage block. <P>SOLUTION: An overhang part 5a overhanging to a projection space to the lower side of a gas passage part 52b on the downstream side of a solenoid valve is formed at a part of a passage block 5 on the lower side relative to the valve hole 64; on the overhang part 5a, a hole part 52d reaching the gas passage part 52b from its undersurface is opened; and a seal part 71 for closing an open end of the hole part 52d is formed integrally with packing 7 interposed between the flange part 21 of the valve casing 2 and the flange part 51 of the passage block 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
