摘要： A massage device has a transmission unit, a massaging member and a base. The transmission unit has a motor, at least one first link rod and at least one second link rod. At least one driving shaft is disposed on a side of the motor, and the first and second link rods both respectively have a first end and a second end. The transmission unit drives the first and second link rods through the motor, with the first and second link rods and the cooperation of the massaging member and the base, the first link rod acts as a swinging arm to make the second link rod to have rocking movements. So that the motor is able to continue to rotate forward to generate the reciprocating swing movements of the member and there is no need to install limit switches to control the forward and reverse rotation of the motor.

摘要： A sprocket transmission mechanism of a massage device contains: a driven box, a pair of hollow holders, and two bendable chains. The driven box is driven by two drive shafts of a motor beside the driven box. The pair of hollow holders are rotatably connected with the two drive shafts respectively and have two grooves, and the pair of hollow holders are connected inside two inner sides of a chair or a bed respectively. The two bendable chains are accommodated in the two grooves individually. The two drive shafts have four sprockets fitted on two sides thereof individually, and two driven sprockets are rotatably connected between the two sides of the two shafts respectively, such that the two bendable chains are inserted into the pair of hollow holders to mesh with and to drive the four sprockets and the two driven sprockets to rotate individually.
