Title:
ROTATIONALLY OPERATED TYPE GAS VALVE DEVICE
Document Type and Number:
Japanese Patent JP3052122
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To lock an operating shaft in an extinguishing position without using special parts and obtain stopper function to pressing operation for lock release in a rotationally operated type gas valve device performing opening/closing operation by rotating the operating shaft normally and reversely between the extinguishing position and an ignition position.
SOLUTION: A recessed part 10h is formed at the hole edge of an axial hole 10e of a shaft guide 10 for supporting an operating shaft 6 in an inserted state. A flange 6b having a rotation stop protruding part 6a at the periphery, and a first protrusion 6d fitted into the recessed part 10h from the front in an extinguishing position are integrally formed at the operating shaft 6. A second protrusion 6e of size enough to pass through the recessed part 10h in such a phase as not to coincide with the recessed part 10h in a rotating angle range between the extinguishing position and an ignition position regulated by a stopper part 10g and a stopper part 10f provided at the shaft guide is integrally formed at a part of the operating shaft 6 protruded backward of the shaft guide 10.
