Abstract

A double gear is provided. The double gear includes a first gear having first row of teeth having a predetermined pitch and a second teeth having a pitch different from that of the first row of teeth, a second gear having a plurality of teeth having the same pitch as that of the first row of teeth of the first gear and combined to the first gear, and a spring for uni-directionally and elastically biasing the first gear with respect to the second gear so that the first row of teeth of the first gear and the teeth of the second gear are out of phase by a predetermined distance, wherein the distance by which the second row of teeth of the first gear and the teeth of the second gear are out of phase is smaller than the distance by which the first row of teeth of the first gear and the teeth of the second gear are out of phase.
