To provide a liquid massage device capable of increasing the ejection force of a nozzle without increasing the capacity of a pump.
This liquid massage device 10 comprises a water tank 11, a sheet 12 covering an upper opening of the water tank 11, a moving carriage 20 moving in the front/rear directions inside the water tank 11, an underwater pump 21 set on the moving carriage 20, and a nozzle mechanism 30 connected to an outlet 23 of the underwater pump 21. A spiral tube 63 for sucking air from the outside of the water tank 11 is inserted from a side into a nozzle 31 of the nozzle mechanism 30. When water is spouted from the underwater pump 21 toward the nozzle 31, jets are ejected out of the nozzle 31. At this time, air is sucked into the nozzle 31 because of the ejector effect, and water including air is ejected out of the nozzle 31.
