Provided to an outer peripheral surface of the shaft member is a protuberance that protrudes diametrically outward and that is formed encircling the axis in a spiral formation. Provided to the inner peripheral surface of the cylindrical member are: a protruding unit that includes a protrusion protruding diametrically inward; and a magnet that is arranged so as to be adjacent to the protruding unit while encircling the axis, and that includes a first surface facing the protuberance and a second surface facing the first surface.
