Abstract
Rotation of a spindle relative to a first cam is reduced. A power tool includes a spindle to receive a tip tool and rotatable about a rotation axis, and a vibration mechanism that vibrates the spindle in an axial direction. The spindle has an outer surface including, in a cross section orthogonal to the rotation axis, a first portion at a first distance from the rotation axis, and a second portion at a second distance from the rotation axis. The vibration mechanism includes a first cam surrounding the spindle, and a second cam located behind and in contact with the first cam.
