Zusammenfassung:A belt drive device includes a first pulley, a second pulley, a first bulging portion, a belt, and a pressing portion. The first bulging portion is formed along an outer periphery of the second pulley to bulge outward in a radial direction of the second pulley at a center of the second pulley in an axial direction of the second pulley. The belt is stretched between the first pulley and the first bulging portion. The pressing portion presses an outer peripheral surface of the belt at a center of the belt in a width direction of the belt.
