Transmission device, driving assembly including the transmission device, and image forming apparatus including the driving assembly

摘要

A transmission device includes a rotatable shaft, a first transmission member, and a second transmission member. The first transmission member includes a first fitting portion fitted coaxially to an outer circumferential surface of the rotatable shaft, and is attached to the rotatable shaft to transmit torque. The second transmission member is rotatably driven by a driving device and includes a second fitting portion fitted coaxially to the outer circumferential surface of the rotatable shaft. The second transmission member is connected coaxially to the first transmission member while the first and the second fitting portions are fitted to the outer circumferential surface of the rotatable shaft.
