<P>PROBLEM TO BE SOLVED: To provide a power tool prevented in cam-out in work and reduced in size. <P>SOLUTION: The power tool 1 includes an electric motor 3 having a rotatable rotor 3A, a hammer 42 rotated by the rotation of the rotor 3A and an anvil 52 hit by the rotated hammer 42. The moment of the inertia of the rotor 3A is larger than the moment of the inertia of the hammer 42. A rotating speed of the rotor 3A when continuously rotating the rotor 3A and a rotating speed when intermittently rotating the rotor 3A are differently from each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
