The cloud body 20 is able to continuously rotate in the same direction as the direction of movement of the waist along the entire passage inside the waist close-type hula hoop 1 in which the corrugated pipe and the length adjusting part communicate. 17 to 19, as shown in FIG. 18, when the pressing plate 92 of the adjustment body 80 is pushed in the direction of the first ① in order to accommodate different waist sizes according to the user, as illustrated in FIG. 18. In the same manner, the hook 84 rotates in the direction of the second ② and is detached from the corrugated pipe 10. At this time, while pulling the corrugated pipe in the direction of the third ③ by the external force can increase the size of the hula hoop of the present invention as desired. After removing the external force applied to the pressing plate after moving the corrugated pipe by a predetermined length, the hook is installed in the corrugated pipe while the hook is rotated in the direction ④ as shown in FIG. Operating in reverse to the above adjustments can reduce the size of the hula hoop.

When the rolling body 20 rolls the corrugated pipe 10, it generates a vibration to massage the user's waist. When the rolling body 20 rolls the inside of the length adjusting part 30, the vibration protrusion 48 (68) acts as the corrugation of the corrugation tube. In addition, since the rolling body 20 is rolled by the reaction of the waist using both legs, the effect of the movement is great.

The present invention has been shown and described with reference to the preferred embodiments as described above, but is not limited to the above embodiments, it should be interpreted by the appended claims. In addition, various modifications and variations may be made by those skilled in the art within the equivalent scope of the technical concept of the present invention and the appended claims.
