A power transmission device includes: a housing; a ball screw device including a nut, a screw shaft, and a plurality of balls; a pulley device including a driving pulley configured to be driven by receiving power transmitted from a power source, a driven pulley fixed to the nut, and a belt wound around outer peripheral surfaces of the driving pulley and the driven pulley; a first bearing and a second bearing disposed between the housing and the nut in a center axis direction parallel with a center axis of the nut; and a preload applying member configured to apply preloads to the first bearing and the second bearing. The first bearing and the second bearing are respectively disposed on both sides of the driven pulley to be a face-to-face combination, and each of the first bearing and the second bearing includes an outer ring engaged with the housing. The outer ring is pressed toward the driven pulley by the preload applying member, and is separated from the driven pulley with a gap formed between the outer ring and the driven pulley.
