PROBLEM TO BE SOLVED: To arrange a device with an armature 8 of a main device and a thermosensible part 9 provided in parallel at a bathtub to close a contact point of the armature 8 when water is collected to a position of water filling, thereby operating a transistor 2 to ring a loudspeaker 3 for alarm and to warm the thermosensible part 9 when the water is warmed to a bathing temperature, thereby actuating a snap switch of a servo main body 10 to operate the transistor 2 so as to ring the loudspeaker 3. SOLUTION: A main body is constructed by providing the thermosensible part 9 and the armature 8 in parallel to close the contact point of the armature 8 when water is filled to a proper level, thereby ringing the loudspeaker 3 through the transistor 2 for alarm. When the water is warmed to a proper temperature for bathing, the thermosensible part 9 is warmed, thereby actuating the snap switch of the servo main body 10 to ring the loudspeaker 3 through the transistor 2.
