Claim 0:
1. A power tool, comprising:
a motor;
a reducer configured to reduce rotation from the motor, the reducer including
at least two stages of internal gears aligned in an axial direction,
a preceding planetary gear in a preceding stage,
a succeeding planetary gear in a succeeding stage adjacent to the preceding planetary gear in the axial direction, the preceding planetary gear and the succeeding planetary gear being configured to revolve within and engage the internal gears, and
at least two stages of gear carriers aligned in the axial direction, a gear carrier of the gear carriers supporting the preceding planetary gear and the succeeding planetary gear radially overlapping with a single pin; and

an actuator configured to be actuated by the rotation reduced by the reducer, wherein:
the preceding planetary gear includes a gear section adjacent to and overlapping the succeeding planetary gear in the axial direction and a bearing section extending from the gear section in the axial direction; and
the succeeding planetary gear is mounted on and around the bearing section such that (i) the bearing section is inside the succeeding planetary gear and (ii) the succeeding planetary gear and the bearing section overlap in a radial direction that is perpendicular to the axial direction.
