8), both can be integrally rotatable. Note that the foot pressing tool is not limited to the illustrated form.

Next, the manner of use of the various pressing tools according to the present invention will be described. Back pressing tool 11 shown in FIG.
Reference numeral 0 denotes a form in which the mounting portions 116 at the lower portions on both ends straddle the two long rectangular shafts 32 at the center of the backrest portion 30, and correspond to the back which requires the user to press as shown in FIG. It is fitted and attached to a portion (substantially the center in the vertical direction of the backrest portion 30). Next, the user sits down on the seat portion 4 and leans the back backward so as to follow the backrest portion 30. In this state, the four press-contact balls 128 in the back pressing tool 110 are in contact with the center of the back, and the parts in contact with the press-contact balls 128 with the weight of the user's own back are pressed. The pressing strength at this time is proportional to the pressing force of the user's back against the pressing ball 128. Also, the number of times of pressing is determined freely by the user himself. Further, the vertical position of the back pressing tool 110 itself can be changed by moving the mounting position of the back pressing tool 110 itself up and down, and the horizontal spacing of the press-contact sphere 128 can be changed by the screw shaft 1.
The rotation can be performed by moving the slider 126 left and right due to the rotation of the slider 22.

In this state, the two right and left press-contact balls 128 of the neck pressing tool 140 contact the rear side portions of the neck, and the press-contact balls 1 are weighted by the weight of the user's own head.
The portion in contact with 50 is in a weak pressing state. In this state, when the pair of left and right long handles 152 is pulled up with both hands, the pair of left and right pressure contact balls 150 move inward with each other. At this time, the center tension coil spring 158
At the same time as a pair of press-contact balls 15
0 moves outward, and can be pressed toward the center of the neck from both sides of the neck in a state where the pressure contact angle between the pressure contact ball 150 and the neck is slightly inclined in the horizontal direction. The pressing strength at this time is proportional to the lifting force of the long handle 152 of the user. Also, the number of times of pressing is determined freely by the user himself. Further, the vertical position of the pair of press contact balls 150 can be changed by vertically moving the mounting position of the neck pressing tool 140 itself.

A shoulder pressing tool 160 shown in FIG. 15 is configured such that a portion of a through hole 164 at one end of a longitudinal non-circular shaft 162 is
7. As shown in FIG. 26, the long rectangular shaft 3 of the backrest portion 30 is provided.
It is attached to a pair of right and left upwardly extending support shafts 80 for insertion of pressing tools provided in the gap between the two, and the sheath-like handle 170 is slid to position the press-contacting ball 168 at the pressing portion of the shoulder. In this state, the user sits down on the seat portion 4, places the back along the backrest portion 30, and manually pushes down the distal end portion of the sheath-shaped handle 170 so that the pressing portion 168 presses the shoulder portion. It can be carried out. At this time, the position of the press-contact sphere 168 in the front-rear direction with respect to the shoulder can be adjusted not only by sliding the sheath-shaped handle 170 but also by tilting the pressing tool insertion support shaft 80 forward.

The foot pressing device 180 shown in FIG.
In a state where a pair of shaft support members 90 shown in FIG. 8 disposed at the lower part of the seat so as to be able to protrude and retract forward and backward from the seat 4 as shown in FIGS. The portions of the bushes 220 at both ends of the long shaft 182 of the foot pressing tool 180 are placed in any of the bearing grooves 94. FIG.
Reference numeral 7 designates a foot pressing device 180 placed between a plurality of bearing grooves 94 for pressing the calf. In this state, the user sits down on the seat portion 4 and the calf is placed above the spherical rollers 190 on both sides. The calf can be massaged by moving the legs back and forth as if riding a bicycle on a bicycle. At this time, the arc-shaped projection 196 provided on the outer peripheral portion of the spherical roller 190 locally presses the calf, so that an effective massage effect can be obtained.

FIG. 28 shows a foot press 180 placed on the tip of a plurality of bearing grooves 94 for pressing the sole. In this state, the user sits down on the seat 4 and By placing the sole of the foot on the upper part of the cylindrical roller 184 and rotating the cylindrical roller 184 while applying a force to the sole, the sole of the foot can be massaged. The pressure at the time of the pressing can be appropriately adjusted by adjusting the pressure applied to each roller by the user.
