Thereby, when putting the foot between the rubbing rollers 16 and 16 and rubbing, when the load applied to the rubbing roller 16 increases, the protrusion 24 of the rubbing portion 22 is initially compressed, but when the load further increases. The elastic body 37 is compressed to retract the pair of rubbing rollers 16, 16 away from each other, thereby preventing an excessive pressure from being applied to the foot as the massaged object. The spacer 40 is provided with two auxiliary rollers 38 that are rotatable. This is used, for example, when stimulating the sole while rubbing the foot with the rubbing roller 16.
[0017]
The rubbing rollers 16, 16 and the rotating roller 25 are covered with a cover sheet 35 which is rich in flexibility. A large number of ribs 36 are formed on the outer periphery of the first base 27 to prevent the cover sheet 35 from being rolled up during massage.
[0018]
As shown in FIG. 5, the cover sheet 35 is composed of a rubbing roller portion 51 covering the rubbing roller 16 and rotating roller portions 52, 52 covering the rotating rollers 25 on both outer sides thereof. , 52, 52 are integrally formed by suturing 54. More specifically, the joint between the rubbing roller 51 and the rotating roller 52 is stitched with a bulge 53. In addition, the rubbing roller portion 51 is made of a fabric that is more elastic than the rotating roller portion 52.
[0019]
As shown in FIG. 1, the stitches 54 are provided on the back side of the cover sheet 35, that is, on the side in contact with the rotating roller 25 and the rubbing roller 16. The size of the rotating roller portion 52 is adapted to fit the outer periphery of the rotating roller 25, and the size of the rubbing roller portion 51 is adapted to fit with the outer periphery of the rubbing roller 16 with play. Is set. The kneading roller unit 51 and the rotating roller unit 52 are given different colors.
[0020]
At one end of the cover sheet 35 (an end opposite to the seam 54 of the rotating roller 52 with the rubbing roller 51), a passage 56 for passing a string 55 is formed. Has been passed. Also, at the other end of the cover sheet 35, three pairs of magic fasteners 57 and 58 which are connected to each other are mounted.
[0021]
In order to attach the cover sheet 35, flanges 59, 59 are formed on opposing walls of the attachment bases 2, 3. More specifically, it is provided around the distal end of a short cylindrical body protruding from the opposing walls of the mounting bases 2 and 3. A fitting groove 60 having a short cylindrical body as a bottom is formed between the flange 59 and the facing wall. On the back side (lower side) between the mounting bases 2 and 3, a support stay 61 is provided integrally with the flanges 59 and 59 as shown in FIG.
[0022]
