摘要 A power transmission device that transmits a rotational driving force outputted from a driving source to a target device to be driven includes: a driving rotor rotated by the rotational driving force; a driven rotor that rotates with a rotary shaft of the target device; and a connection member. The connection member has a plate shape extending perpendicular to the rotary shaft. The connection member is connected at least one of the driving rotor and the driven rotor, and is capable of connecting the driving rotor and the driven rotor to each other. The connection member has a through hole, and the driven rotor has an overlapping portion disposed overlapping with the through hole when viewed in the axial direction of the rotary shaft.
