PROBLEM TO BE SOLVED: To provide: a mounting structure of a gas device in a gas treatment apparatus capable of surely and easily connecting a gas device to a gas inflow part or a gas outflow part; and a gas detector capable of easily forming a predetermined gas piping structure.SOLUTION: An adapter comprises an adapter main body having a gas device holding part connected to a flexible tube whose tip end is mounted with a rigid nipple and a flexible tube holding part, and the nipple is held, by the flexible tube holding part, in a loosely fitting manner in a radial direction while movement in an axial direction is restricted. The adapter main body is mounted to a gas device mounting part, so that the gas device holding part can hold a gas device while the nipple is being connected to a gas inflow port or a gas outflow port of a gas treatment apparatus, to form a mounting structure of a gas device. According to the above mounting structure, a gas detector has a structure in which a gas sensor is connected to a gas flow path. |
