PURPOSE: Provided is an acupressure ball, in which four semicircular housings are freely rotated in all directions and many acupressure bosses are formed on an outer surface of the housing. CONSTITUTION: The acupressure ball includes a pair of balls having four semicircular housings(6a,6b) cut along a center of the ball. Many bosses(12) are formed on an outer surface of the housing. The pairs of balls are pivotally connected to each other by a connecting rod. The housings forming one ball are symmetrically faced to each other, and inserting grooves(14a,14b) are formed at contacting surfaces of the housing. Ends of the connecting rod are engaged to the inserting grooves. The semicircular housings are freely rotated in a lateral direction. |
