BURIED TYPE GAS PLUG FITTING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To enable a buried type gas plug fitting structure for use in fixing a gas plug main body in a wall plate through a front plate (14) and a back plate which are pressed against and fixed around a through-pass hole (30) of a wall plate (3) from its front and rear sides to assure air-tightness and thermal insulation in an interior area without having any relation with a shape of the back plate. ! SOLUTION: A gas plug main body (45) having a back-plate (20) is stored in an air-tight cover (1) and one end releasing part (13) is fastened around a pipe (40) by a fastening member under an outer periphery air-tight state. The surface of a post-fitting frame (11) is adhered to the inner surface of the air-tight cover (1) by a frame-like seal packing (12) so as to form a window part (10) at the air-tight cover (1) along an opening (11a) of the post-fitting frame (11). The surface of the post-fitting frame (11) is attached over an entire circumference around a through-pass hole (30) at the rear s
