PROBLEM TO BE SOLVED: To promote the blood circulation to loosen the tonus by providing the device with a push ball to be slid on the sliding track of a sliding guide to make contact with the body independently from a body support means, and a pressurizing means for pressurizing the air of a cylindrical hollow body axially contracting and extending in contact with the push ball. SOLUTION: When a massager device is operated, a control device 15 drives an air pump 15 to supply and pressurize air to a bellows 12 in the valve element direction of a drive valve 14. The bellows 12 is then extended to slide a push ball 1 in the inside sliding track of a sliding guide 10. The part to be massaged of the back, with which the push ball 11 makes contact, is massaged by the slide of the push ball 11 as the finger pressure of selectively massaging the muscular fibers without changing the direct contact area to the skin. At this time, even if the person to be massaged adds an excessive load to the push ball 11 depending on the manner of adding the weight to a body support means 9, no driving force exceeding the air pressure is added to the push ball 11, and the person can be massaged without receiving any excessive finger pressure- like stimulation.
