PROBLEM TO BE SOLVED: To provide a massage machine capable of simplifying the structure related to a connection of a drive shaft of a motor to a rotary shaft of a worm gear and effectively exerting the absorption of core deviation between the drive shaft and the rotary shaft, and the reduction of vibration and noise. SOLUTION: The rotary shaft 5 of a worm 4 provided in an input side of a mechanism part 3 for making an output member 2 perform a predetermined operation, and the drive shaft 7 of the motor 6, or the drive source of the output member 2, are disposed substantially coaxially at some interval apart. A drive shaft fitting part 9 is provided at one end side opening of a shaft joint member 8 consisting of a hollow cylindrical elastic body and the drive shaft 7 is fitted in the drive shaft fitting part 9, while a rotary shaft fitting part 10 is provided at one end side opening in the other end of the shaft joint member 8 and the rotary shaft 5 is fitted in the rotary shaft fitting part 10.
