PROBLEM TO BE SOLVED: To provide a massage device with which massage action is made by serially injecting/exhausting air into/from a plurality of air bags via a distributor and, when the massage action is terminated, the action is continued until the distributor reaches exhaust position and then the action is terminated, in which pump and distributor are directly terminated with a cam switch driven by motion of the distributor to simplify construction of electric circuit for driving the pump and distributor.SOLUTION: The massage device comprises: a pump 400 to be an air supply source; a motor 210 driving a distributor 200; a power switch 110 optimally supplying power to the pump 400 and the motor 210 to drive them; and a limit switch 240 which is connected in parallel to the power switch 110 and being operated by a cam 232 making an action together with a distributor 200 so that it is turned on at a position where the distributor 200 supplies any of the air bags 300 with air and it is turned off at a position where the distributor 200 discharges air from at least any one of the air bags 300.SELECTED DRAWING: Figure 2 |
