Valve device

A valve device configured to be fitted to a gas tank in which high-pressure gas is stored, the valve device comprising:

• a body in which a gas flow passage is provided, the gas flow passage providing communication between an inside and an outside of the gas tank;
• and
• a check valve provided in the gas flow passage, the check valve including a poppet that suppresses discharge of the gas inside the gas tank to an outside of the body, and a valve seat with which the poppet makes contact and from which the poppet separates, wherein:
• the poppet excluding a block portion is in a form of a hollow shaft, the block portion being located at a distal end of the poppet and having a taper shape, and the poppet has at least one side hole that provides communication between an inside and an outside of a portion of the poppet, the portion being in the form of the hollow shaft;
• and
• the at least one side hole extends obliquely with respect to a central axis line of the poppet such that the at least one side hole extends along a gas flow direction inclined with respect to a direction in which the poppet moves when the check valve opens.
