PROBLEM TO BE SOLVED: To sufficiently secure seal performance of a pressure adjusting valve over a long period, in a gas fuel regulator having a metallic valve element. SOLUTION: This gas fuel regulator has a pressure adjusting valve arranged in a gas fuel passage and performing valve opening-closing operation by sliding the metallic valve element 8A in response to a pressure variation in a pressure adjusting chamber 8, and sends out gas fuel to the downstream side while adjusting pressure to predetermined pressure. Electroless Ni-P plating processing including PTFE is applied to a valve element surface of the pressure adjusting valve 4A. COPYRIGHT: (C)2009,JPO&INPIT
