Abstract
A power tool has a motor having a rotary shaft, an eccentric shaft configured to be rotated around a rotation center axis of the rotary shaft, and a balancer configured to rotate with the rotary shaft. When viewed along the rotation center axis, (1) a first imaginary line passes the rotation center axis and an eccentric axis, (2) an imaginary perpendicular line crosses perpendicularly to the first imaginary line and passes the rotation center axis, (3) a center of gravity of the balancer is located in a region on a side opposite to the eccentric axis across the imaginary perpendicular line; and (4) a second imaginary line passes the rotation center axis and the center of gravity of the balancer and (5) the second imaginary is inclined at an inclination angle larger than 0° and smaller than 90° in a direction opposite to a rotating direction of the rotary shaft.
