摘要：
A drive device includes a first shaft, a second shaft disposed at a position deviated from a shaft line of the first shaft, a drive source that drives the first shaft to rotate, and a drive force transmitting unit connecting the first shaft to the second shaft via the drive force transmitting unit to transmit a drive force of the drive source from the first shaft to the second shaft. The drive force transmitting unit includes a reverse preventing mechanism that prevents the first shaft from being rotated in a reverse direction. The reverse preventing mechanism includes a one-way clutch, and the drive force transmitting unit further includes a reduction mechanism that reduces a rotational speed of the one-way clutch to be lower than a rotational speed of the first shaft.
