摘要

PROBLEM TO BE SOLVED: To avoid the occurrence of noise or the like as a result of vibration of a valve body when equipment creating pressure fluctuation such as a pump or the like is installed near a vacuum breaker and the pressure fluctuation is transmitted to the valve body of the vacuum breaker. SOLUTION: In a bidet arranging a vacuum breaker 74 in the neighborhood of a device 94 producing pressure fluctuation, a temperature-sensing spring 97b consisting of a shape memory element urging the vacuum valve body 97a to an air inflow path side of the vacuum breaker is provided and a bias spring 97c urging a vacuum breaker valve body 97a in the reverse direction of the temperature sensing spring 97b is provided, and therefore an air inflow path 97b of the vacuum breaker can be definitely interrupted so that troubles such as the occurrence of fluttering and abnormal sound from the vacuum breaker following the pressure fluctuation can be eliminated.
