A power transmission device includes: a first pulley; a second pulley having a diameter equal to or larger than a diameter of the first pulley; a belt wound around the first pulley and the second pulley; and a detection unit configured to detect a displacement of the belt in a direction intersecting the surface of the belt. The detection unit is configured to detect the displacement of the belt at a predetermined measuring point. The distance from the border between a portion where the belt and the first pulley are in contact with each other and a portion where the belt and the first pulley are not in contact with each other, to the measuring point is equal to or smaller than the diameter of the first pulley.
