A cyclically driven, straightly and reciprocally moving massage device for positioning rotary massage components is installed in the interior section of a back massage chairs or pillows, enabling an axial moving applied upon the user. The massage components of the device are capable of rotating and straightly moving continuously. The device consists of a base plate having a driving gear and a driven gear, and a base mounting plate. The base plate has studs for pivotably mounting the driving disk and driven disk, respectively. A cyclically moving chain or a timing belt is installed around the outer circumference of the driving disk and the driven disk so as to formed with a loop for transmitting moving forces. Furthermore, different structural type massage components are selectively utilized to provide continuous rotation modes without any power supply or circuit wiring on the base mount to thereby facilitate the maintenance of motion.
