PROBLEM TO BE SOLVED: To solve generation of gear sound caused by changing in teeth contact of gears during massaging action in a massaging machine. SOLUTION: In a massaging machine wherein a pair of arms 32 and 32 are freely rotatably pivoted through inclined shafts 31 whose inclination directions are symmetric on a massaging shaft 3 and apexes of links 6 and 6 for restricting rotation of the arms 32 and 32 are pivoted and connected with both arms 32 and 32 to support the base ends of the links on the supporting member and a motor 43 is connected with the massaging shaft 3 through a gear rotation transmitting means 4 and the arms 32 and 32 are rocked by rotating the massaging shaft 3 and therapeutic fingers 35 and 35 on the arms 32 and 32 are allowed to approach and separated left and right to perform massaging action, a crank part 60 is linked with the above described link 6 and when the therapeutic fingers 35 and 35 approach each other as near as possible and move in the separating direction, change from compression to stretching or change from stretching to compression acting on the link 6 is relaxed to relax teeth contact of the gears.
