This is for the loads in which the wheel fastening grooves are installed perpendicularly to the rotating shaft so that the wheel fastening groove can be rotated in an eccentric state. As a result, the rotational force was not smoothly rotated, and as a result, the rotational force of the eccentric wheels was slowed down, so that the turning and rotational movements were not precisely made in accordance with the pitching direction of the player.

The present invention not only overcomes the structural limitations of traditional curling stones that are rolled on ice but also improves the structure so that it can be easily played for indoor leisure on non-ice wood or genius tables. It is lightweight and made of synthetic resin, so that the eccentric wheels fastened to the stone floor can be smoothly eccentrically rotated against the direct load of the stone body, which is transmitted in its own rotational motion and in the axial direction of the rotating shaft. An object of the present invention is to provide a leisure curling stone that can be precisely converted and rotated.
