PROBLEM TO BE SOLVED: To provide a hydraulic massage device capable of efficiently reducing burdens on a user when lying on a supporting sheet. ! SOLUTION: A water bed performs massage by jetting water filled up inside a closed space, which is formed by a water tank 10 and a supporting sheet 110, to a user. The supporting sheet 110 is arranged above the water and supports the user, and the water filled up inside the closed space is jetted toward the supporting sheet 110 by a jetting part. The air bag 30 is provided in the closed space, and expands by gas sending inside. When the air bag 30 is made into a biggest state by air sent into the inside of the air bag 30, pressure inside the closed space becomes high. Herewith, the supporting sheet 110 becomes hard to bend, so that the user can seat himself/herself on the supporting sheet 110 smoothly and then can lie down on the supporting sheet 110. !
