Abstract:
1. A power tool comprising: a housing; a motor within the housing for actuating a working member of the tool, the motor having a stator and a rotor adapted to rotate about a first axis relative to said stator; and first vibration attenuators which attenuate vibrations transmitted from said stator to said housing at least in a direction substantially parallel to said first axis; wherein the stator is displaceable relative to said housing in a direction substantially parallel to said first axis, and the first vibration attenuators comprises biasers which resist said displacement of said stator relative to the housing at least in a direction substantially parallel to said first axis; wherein said biasers comprises at least one resilient member; and wherein said biasers comprise a plurality of first said resilient members circumferentially spaced around said first axis and a plurality of second said resilient members offset from said first resilient members in a direction parallel to said first axis.
