PROBLEM TO BE SOLVED: To provide a float and a warm water supply device using the same which are usable even in use environment which is constant high temperature condition and where additional temperature changes between high temperature and low temperature.SOLUTION: Disclosed is a float 20 which is used in a float switch 10 for detecting a water level of hot water 9 stored in a hot water tank 1 and which is elevated in linkage with water level fluctuation of the hot water 9. In the float 20, a plurality of spaces 21b are provided formed by barriers 21a. Even when a crack, hole and the like are generated in the float 20, a buoyant force larger than a certain level which is required as the float 20 used in the float switch 10 is maintained by partly preventing the hot water 9 from entering inside of the float 20.SELECTED DRAWING: Figure 1 |
