Abstract

There is provided a drive power transmitting mechanism that can transmit drive power losslessly and can be used in environments where silence is required. The drive power transmitting mechanism includes a rotor having a first outer circumferential surface and rotatable about a first rotational axis, a rotor having a second outer circumferential surface pressed against the first outer circumferential surface and rotatable about a second rotational axis due to a frictional force produced between the second outer circumferential surface and the first outer circumferential surface, a gear rotatable in unison with the rotor about the first rotational axis, and a gear rotatable in unison with the rotor about the second rotational axis, in which the gear and the gear are brought into mesh with each other when the second outer circumferential surface slips against the first outer circumferential surface.
