A check valve (42) is provided in a gas fuel supply passages (34) corresponding to a gas canister (13) containing the gas fuel of a low working pressure (propane gas). The check valve (42) prevents the gas fuel of a higher working pressure (butane gas) from flowing from a downstream side of the check valve (42) to an upstream side of the check valve.",
