PROBLEM TO BE SOLVED: To provide a technique effective for properly discharging insoluble matters such as tar accumulating inside a regulator main body, in an LPG regulator. SOLUTION: In the LPG regulator 10 disposed between an LPG cylinder 1 and an engine 2, a hose 62 made of, for example, transparent resin material or glass material is connected to a position corresponding to a C chamber 43. Since the C chamber 43 communicates with the hose 62, a liquid surface level and an accumulation amount of the insoluble matters such as tar in LPG accumulated in the C chamber is directly visible through the hose 62. Therefore, an operator can easily grasp a maintenance time suitable for discharge work of the insoluble matters such as tar through the hose 62. COPYRIGHT: (C)2004,JPO&NCIPI
