特徴とする。Means for Solving the Problems The present invention provides a flywheel that is rotated by driving a pedal,
In a stationary bicycle-type health device equipped with a load device having a roller pressed against the outer circumference of a flywheel, a disc-shaped left and right side plate, a weight piece fixed to the side plate, and a center of rotation of the side plate. A flywheel is composed of a fixed hub and an elastic band having a V-shaped cross section that fits around the outer periphery of the side plate. The peripheral length of the elastic band is formed to be substantially equal to or shorter than that of the outer periphery of the side plate, and the long side and the short side are short. The left and right side plates are fitted in the groove width between the sides.

合させているので、円周方向，左右方向とも側板から大
きくずれることはない。しかも、はずみ車が高速回転し
ても、弾性帯は浮き上ることもない。Since the roller of the load device is pressed against the ring-shaped elastic band provided on the outer periphery of the work flywheel, the contact between the two is softened and the load is stabilized. Further, since the elastic band has a V-shaped cross section and is fitted to the side plate, it does not largely deviate from the side plate in both the circumferential direction and the left-right direction. Moreover, even if the flywheel rotates at high speed, the elastic band does not float up.
