Abstract
Provided is a valve unit including a first gas flow channel to a gas tank and a second gas flow channel branching off from the first gas flow channel and leading to a gas-consuming device. The valve unit can avoid the entrance of water, which may be included in gas, into the second gas flow channel. The first gas flow channel to let gas from the outside in has a bend. The first gas flow channel has a communication port to the gas tank at an end downstream of the bend. A second gas flow channel branches off at a branching part between the bend and the communication port, and the second gas flow channel leads to the gas-consuming device. A straightening member is disposed between the bend and the branching part, and is to straighten the gas flow from the upstream to be parallel to the direction of the first gas flow channel.
