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 1 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, a cloth 130 covers the supporting sheet 110 from the upper surface side, and the front end of the supporting sheet 110 is fixed on an axis 162 of a lever 160. An operator operates a grip 163 of the lever 160 and thereby the lever moves downward, so that the cloth 130 is pulled to enhance tension applied to the cloth 130. Herewith, the cloth 130 supports the user even when the user seats himself/herself on the supporting sheet 110, so that sinking of the user is suppressed. Consequently, the user can lie on the supporting sheet 110 smoothly. ! COPYRIGHT: (C)2015,JPO&INPIT |
