Abstract
To provide a hula hoop having such strength and rigidity that can endure a predetermined competition or performance, which relaxes an impact imparted to a part of a body.SOLUTION: This hula hoop F includes a cylindrical body part 1 forming an annular contour, and a projection part 2 formed so as to project inward from an inner surface of the body part 1. A ratio between a thickness W3 of the body part 1 and a projection amount W4 of the projection part 2 is 1:2 to 8:1. At least one set of the projection part 2 is formed at positions facing each other and is formed continuously in an annular direction of the body part 1.SELECTED DRAWING: Figure 2A
