PROBLEM TO BE SOLVED: To provide a noiseless, small and inexpensive massage device concerning the massage device in which a massage operation is given by intermittent air supply/exhaust to air cells. SOLUTION: This device is provided with an air pump 27 having an intake port 25 and a discharge port 26, a pump case 24 having an air communicating part 36 at the outer side of the air pump 27, a change-over valve 31 connected from the discharge port 26 of the pump 27 by way of an air supply pipe 30, an air supply/exhaust pipe 32 connecting the valve 31 to the air cells 21 and a return exhaust pipe 33 for returning exhaust air from the valve 31 to the pump case 24. Then exhaust air from the air cells 21 is returned to the pump case 24, an exhaust noise is shielded by the pump case 24, an extra control valve except the change-over valve 31 is not required since the pump case 24 is provided with the air communicating part 36, the number of parts is reduced and piping is easily connected. Then the objective quiet, small and inexpensive massage device is realized.
