Support to exercise. The reduction ratio of the reducer 210 may be set by the number of teeth of the outer gear 211 and the inner gear 213. Here, in the inner gear 213, the number of teeth smaller than the number of gears formed along the inner surface of the outer gear 211 is set on the outer side, and the rotational movement of the shaft 130 is reduced to reduce the rotational movement. Not only does it support eccentric rotational motion.

The outer gear 211 and the inner gear 213 according to an embodiment of the present invention can be confirmed through FIG. 5. As shown in FIG. 5, the outer gear 211 forms the number of teeth of a gear therein, and meshes with the number of teeth of a gear formed outside the inner gear 213. The number of teeth of the gear formed on the outer side of the inner gear 213 is at least one smaller than the number of teeth of the gear formed inside the outer gear 211, so as to reduce the rotational movement of the shaft 130, as well as the eccentric rotational movement.
