The bearings are fitted into the bearing fitting holes formed in the two external gears, and the inner peripheral surfaces adjacent to each other of the bearing fitting holes of the two external gears have holes extending in the axial direction of the input shaft. A planetary gear speed-up/deceleration mechanism characterized in that a cutout-shaped relief portion is formed with a length approximately half the width of an external gear.
