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.
Claims6
A power transmission mechanism comprising:
- an operation unit;
- a drive source configured to generate power for operating the operation unit;
- and
- a gear train mechanism including a plurality of power transmission gears of which rotation centers are arranged in a staggered pattern when viewed from an axial direction and configured to transmit the power by rotating the plurality of power transmission gears, wherein
- the gear train mechanism includes a first gear as the power transmission gear located most downstream in a power transmission direction in which the power is transmitted from the drive source to the operation unit, a second gear as the power transmission gear engaged with the first gear and transmitting the power to the first gear, and a dummy gear not having a function of transmitting the power, and
- the dummy gear is engaged 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.
