  • the massage bracket 609 has a first end portion and a second end portion defining a bracket body therebetween, a guiding bar 609d protruded laterally from the first end portion, and a bore 609e formed through the bracket body for receiving the bolt shaft of the eccentric wheel 617 such that when the bolt shaft of the eccentric wheel 617 moves circumferentially, the massage bracket 609 moves accordingly.
  • the guiding block 623 is mounted on the shielding member 632 and has a crescent-like guiding slot 623a for receiving the guiding bar 609d of the massage bracket 9 such that when the massage bracket 609 moves in response to the circumferential movement of the bolt shaft of the eccentric wheel 617, the guiding bar 609d of the massage bracket 609 moves back and forth along the crescent-like guiding slot 623a.
  • the massage foot 652 is mounted on the second end portion of the massage bracket 609 such that when the guiding bar 609d of the massage bracket 609 moves back and forth along the crescent-like guiding slot 623a of the guiding block 623, the massage foot 652 taps back and forth along an arc line corresponding the crescent-like guiding slot 623a of the guiding block 623.
  • the massage bracket 609 and the massage foot 652 are molded as a single member. Further, the massage foot 652 may have a plurality of thermal and/or optical sources 654.
  • the motor 604 when the motor 604 is activated, it drives the worm 605 to rotate, the rotation of the worm 605 results in the rotations of the worm wheel 608 and the first gear 634, the rotation of the first gear 634 results in, in turn, the rotations of the first pinion gear, the second gear 637, the second pinion gear, thereby moving the carriage 603 along the rack 640.
  • the rotation of the worm wheel 608 results in the rotation of the driving shaft 20.
  • the rotation of the driving shaft 620 results in the rotation of the eccentric wheel 617, which causes the bolt shaft of the eccentric wheel 617 to move circumferentially around the driving shaft 620.
  • the circumferential motion of the bolt shaft of the eccentric wheel 617 results in the circumferential motion of the massage bracket 609 around the driving shaft 620. Additionally, the massage bracket 609 also subjects to a motion back and forth along an arc line that is corresponding to the crescent-like guiding slot 623a. Therefore, the two motions cause the massage foot 652 to tap back and forth so as to provide tapping massaging effects.
