Referring to FIGS. 8A and 8B, the conventional training rotary plate is formed as a rectangular plate as a whole, and a lower surface is formed to be curved so that the user can rotate while one leg is raised.

A grid-shaped rib is formed in a square-shaped groove formed in the upper surface of the rotary plate, and a cushion member is attached on the rib.

The grid-like ribs are used to prevent warpage of a rotating plate made of a synthetic resin material and to reduce raw material consumption, and it is difficult to use the ribs because the ribs cause pain in the foot without the cushion member.

Further, since the cushion member is adhered in a state in which the cushion member is in line contact with the rib, there is a problem that the adhesive force is weak and the cushion member is easily peeled off from the rotary plate as shown in Fig.

In addition, since the process of attaching the cushion member must be performed after molding the rotary plate, the process becomes complicated and the manufacturing cost increases.

On the other hand, since the conventional rotary plate is formed in a rectangular shape corresponding to the shape of the foot, there is a problem in that it is not suitable for training to rotate while holding the heel.

It is an object of the present invention to provide an anti-warp portion on the lower surface of a rotating plate, thereby providing an anti-slip protrusion in place of a separate cushion member on the upper surface while maintaining the structural strength. So that the manufacturing process can be simplified and the cost can be reduced accordingly.
