PROBLEM TO BE SOLVED: To provide a thermal fuse adaptor, which is simplified for assembly, and operates without fail, by reducing pressure loss and also manufacturing cost. SOLUTION: The thermal fuse adaptor is so composed that it is attached with a shut-off valve 32 downward by using a holding frame 27 in gas duct 22 of the adaptor body 21, and the shut-off valve 32 is fixed to the holding flame 27 with a holding pin 36 and solder member 39. The thermal fuse adaptor is constructed in such a manner that the older section 39 dissolves when fire breaks out, and the shut-off valve 32 will fall down by its self weight while it is guided with the holding pin 36, thus it is in close contact with the valve sheet 23 resulting in shutting off the gas.
