PROBLEM TO BE SOLVED: To correct the motion of an infant so that a crawling can be smoothly performed by providing a holding utensil to prevent the infant from rolling over when the infant crawls, on both sides of a supporting board equipped with an attaching utensil which is attached to an area around the waist of the infant. SOLUTION: An attaching utensil 4 is fitted to the vicinity of the center of a supporting board 2. For the attaching utensil 4, at four locations in the longitudinal direction of the cylindrical attaching body 4a, a stretchable attaching piece 4b, on the rear surface of which an uneven engaging surface 4b1 is formed, is provided. Then, on the upper surface of the waist of an infant, the supporting board 2 is placed. Then, the attaching pieces 4b of the attaching utensil 4 are stretched, and the engaging surfaces 4b1 of the attaching pieces 4b, which are confronted each other in the vicinity of the belly of the infant, are superposed and attached. In this case, when the infant tilts to the right side, a holding utensil 3 on the right side hits a floor surface, and stops the tilting. Also, when the infant tilts to the left side, the holding utensil 3 on the left side hits the floor surface, and stops the tilting. Thus, by training in such a manner, the infant can crawl in one to three months.
