PROBLEM TO BE SOLVED: To provide a detergent-injecting device for a bathtub-washing system which is formed into a unit, and separately arranged from an automatic bath system, and in addition, of which the wiring can be easily performed. SOLUTION: This detergent-injecting device 10 for the bathtub-washing system belongs to the automatic bath system 24 which feeds hot water into a bathtub 26, and at the same time, performs an additional heating of the hot water in the bathtub 26 when required. Such a detergent-injecting device 10 is equipped with a washing liquid, tank 11, a pump 15, a flow rate sensor 14 and an electromagnetic valve 17, and a control unit 16 for them. In this case, the washing liquid tank 11 stores a washing liquid 12. The pump 15 pumps up the washing liquid 12 in the washing liquid tank 11, and feeds it to a washing nozzle 31 which is provided in the bathtub 26. The flow rate sensor 14 and the electromagnetic valve 17 are serially connected with the pump 15. The whole is housed in a separate case 10a. Then, the transmitting/receiving of signals is performed through a few communication wires 32a between the control unit 16 and the main control device 33 of the automatic bath system 24.
