A torsion washer of the present disclosure includes a base portion and an elastic unit extended from the base portion. The elastic unit includes an external elastic arm and a torsion-adjusting arm arranged inside the external elastic arm. A space surrounded by the base portion and the external elastic arm is divided into a hole and a slot, in air communication with the hole, by using the torsion-adjusting arm. A distance, i.e., a radius, between the external elastic arm and a center of the hole is larger than a distance, i.e., an interference distance, between the torsion-adjusting arm and the center of the hole. Moreover, the present disclosure provides a torsion device including a plurality of the torsion washers and a shaft coupling through the holes of the torsion washers, and the shaft is configured to selectively contact each torsion-adjusting arm.
