A massage mechanism includes a connecting seat, a supporting seat assembly, upper massage arms, lower massage arms, a kneading shaft and a first driving assembly. The first driving assembly is used for driving the kneading shaft to rotate, such that a connecting member and a connecting shaft are driven to perform a reciprocating motion on each supporting seat assembly, and upper massage rolling wheels and lower massage rolling wheels are close to each other or away from each other, so as to achieve a shoulder clamping action. The two upper massage arms and the upper massage rolling wheels are driven to be close to each other or away from each other, and the two lower massage arms and the lower massage rolling wheels are close to each other or away from each other, so as to achieve a kneading action.
