PROBLEM TO BE SOLVED: To provide an inexpensive "sole massage machine for largely moving joints" with a simple structure, which performs sole massage and allows a user to do exercise to largely move the joints of a knee and a shoulder, etc., as the machine for the health promotion of a healthy person and for the rehabilitation of a person who cannot smoothly move the joints since he/she assumes the same posture due to aging or a disease, etc. SOLUTION: Flanges 2, which are ellipses, etc., with a contour being three times (one example) as big as the "peripheral length of the shaft 1" and are not concentric with the shaft, are provided on both sides of a shaft 1 for massaging the sole. When the sole is put on the shaft 1 with the 10 cm peripheral length, so as to be moved by 10 cm and to allow the shaft 1 and the flanges 2 to rotate once, a ratio between "a movement distance of a contact point between the sole and the shaft 1" and "a movement distance of a contact point between a floor and the flange 2" is the same as the ratio between "the peripheral length of the shaft 1" and "the peripheral length of the flange 2". Thus, the shaft 1 (the massage machine) is moved by 30 cm on the floor via the flanges 2, and the sole on the shaft 1 is moved by 40 cm (10+30) with respect to the floor, so that the joint of the knee, etc., is more largely moved compared with a conventional machine. Besides, the flanges 2 are the ellipses, thereby preventing the machine from rolling to be separated far from the user. COPYRIGHT: (C)2010,JPO&INPIT
