A motor 3 incorporating roller 1 features a power transmission member 4, with means in addition to an interference fit, such as a rivet (35, fig.7c), fixedly joining the member 4 to the surrounding roller body 11. The transmission member 4 further has a particular shape, of convex and concaved outer portions, and an elastic core. These features may help with the prevention of slippage between the transmission member 4, and the surrounding roller body 11, and alignment of the transmission member 4, on a motor drive shaft 46. |
