Abstract
A power transmission mechanism including an operation unit, a drive source, and a gear train mechanism including a plurality of power transmission gears of which rotation centers are arranged in a staggered pattern as viewed from the axial direction. The gear train mechanism includes a first gear located most downstream in the power transmission direction, a second gear that engages with the first gear, and a dummy gear that does not have a function of transmitting power. The dummy gear engages with the first gear and has a rotation center arranged in a staggered pattern with respect to the first gear and the second gear as viewed from the axial direction.
