VALVE DEVICE

PROBLEM TO BE SOLVED: To provide a valve device reducing a mounting space and improving ease of attachment. SOLUTION: The valve device 2 is installed on a gas tank 1 capable of storing high-pressure hydrogen gas, and opens and closes the filling passage 3 of the hydrogen gas. The valve device 2 includes a housing 10 with a housing section 4 provided inside, a first check valve 21 and a valve pressing member 30, which are mounted to the housing 10 and form a through-hole bringing the housing section 4 and the filling passage 3 into communicate with each other. The housing 10 is formed with a filling port 11 bringing the outside and the housing section 4 into communicate with each other. The housing section 4 receives a filter 17 arranged between the filling port 11 of the housing 10 and a through-hole 22a of a passage member 20, and a ball valve 19 movable between the filter 17 and the filling port 11 by a flow of the hydrogen gas. When the hydrogen gas in the gas tank 1 flows into the housing section 4, the ball valve 19 moved to a filling port 11 side seats on a valve seat 13 and closes the filling port 11.
