Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show the overall configuration of a chair-type massage machine 1 according to the present invention. In FIGS. 1 and 2, a chair-type massage machine 1 includes a seat 3 supported by legs 2 and a backrest 4 provided at the rear of the seat 3.
And a footrest 5 provided below the front part of the seat 3,
Armrests 6 provided on both left and right sides of the seat 3. The backrest 4 is configured to be reclined by a reclining device 7 with the rear end side of the seat 3 as a fulcrum.

A mechanical massage device 8 is built in the left and right central portions of the backrest 4 so as to be able to move up and down. Massage device 8
As shown in FIG. 4, a plurality of treatment elements (massaging balls, massage rollers), a massage motor 10, and the rotational power of the massage motor 10 are transmitted to the treatment element 9 to Transmission mechanism 11 that allows the user to perform kneading and beating operations
And a support frame 14, and the massage device 8 is configured to be able to move up and down (up and down) in the backrest portion 4 by the lifting and lowering means 13. The elevating means 13 employs a mechanism for elevating the massage device 8 by rotating a feed screw 15 screwed to a support frame 14 of the massage device 8 by an elevating motor 16.

The elevating means 13 can be replaced by a mechanism using a winding drive mechanism, a meshing structure of a rack and a pinion, or an elevating drive structure using a fluid pressure cylinder or the like. The transmission mechanism 11 of the massage device 8
As shown in FIGS. 4 to 6, a drive unit 21 having a kneading operation shaft 19 and a hitting operation shaft 20 projecting to both left and right sides, a pair of left and right drive arms 25 held by the operation shafts 19 and 20, A support arm 26 is fixed to the distal end of the drive arm 25, and the treatment element 9 is attached to both upper and lower ends of the support arm 26.

The drive unit 21 described above is configured to perform a kneading operation by extracting a left-right moving component to the drive arm 25 via the kneading operation shaft 19 from the rotational power of the massage motor 10, and the rotation by the massage motor 10. It is possible to switch the state in which the driving operation is performed by extracting the forward and backward swing components from the driving arm 25 via the driving operation shaft 20 as required. Operation axis 1
Reference numerals 9 and 20 are disposed in parallel to each other in the left-right direction, and are rotatably supported by the case of the drive unit 21 via bearings. One of these operation shafts 19 and 20 is selected by the massage motor 10 via the transmission mechanism 11 and is driven to rotate in the direction of the arrow A or B shown in FIG.
