Abstract

PROBLEM TO BE SOLVED: To provide an excellent hitting massage effect by performing an almost vertical reciprocating motion to a part to be treated to a person to be treated. SOLUTION: When a motor 12 for hitting is rotated, the rotation is converted into the reciprocating operation in a vertical direction of rods 51 and 52 by an operation conversion mechanism 14. Levers, supporting arms 60 and 61 and leaf springs connected to the operation conversion mechanism 14 by the rod 52 convert the reciprocating operation in the vertical direction of the rods 51 and 52 to the reciprocating operation in back and forth directions of treaters 10a and 10b for approaching/separating to/from the person to be treated. Coil springs 82 and 83 repulsively displace the treaters 10a and 10b to the person to be treated when the operation of separating the treaters 10a and 10b from the person to be treated is ended.

Simultaneous Striking Operation When a striking operation is simultaneously performed on the patient by the striking treatment elements 10a and 10b, the striking motor 12 is rotated in a direction opposite to the predetermined direction. When the motor 12 is rotated in the reverse direction, the rotating shaft 21 rotates in the direction of arrow D1 in FIG. Accordingly, as an example, the locking portions 25 of the locking pins 25 and 26 are formed by the protrusions 33 of the eccentric collars 31 and 32,
34 starts rotating around the rotation axis 21 in the direction of arrow D1. As a result, the eccentric collars 31, 32 begin to be pushed downward in FIGS. 1 and 2 while stretching the coil springs 82, 83 against the spring force of the coil springs 82, 83.
