Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fixture structure in which a cover does not drop from a main body and provide a hot water supply device.SOLUTION: A cover is fixed to a main body by using a screw 31 having a shank of which diameter is smaller than a thread hole and formed with a groove longer than its depth between an extremity end side thread part 31a and a base end side thread part 31c. In this case, spaced-apart distances F, F' between the thread holes 21f and 21g on a bracket 21e are defined as E+H'+Ftan , E'+H+F'tan '
