Abstract of the Disclosure A chain saw including a flexible, resilient skid mounted by means providing torsional and axial stress relieving action whereby enhanced vibration isolation is obtained and certain resonant vibration is eliminated. A skid for use in a chain saw powered by a vibration inducing drive assembly. The skid has a flat portion for resting the saw on a surface, a foot rest portion, and an upwardly directed rear portion, and is connected to the remainder of the chain saw structure by a pair of attachment means. The first attachment means connects a front portion of the skid and a front handle to the drive assembly and provides for axial stress relieving relative motion between the skid and drive assembly. A second attachment means connects the upwardly directed rear portion of the skid to a rear handle and provides for torsional stress relieving relative motion between the skid and the handle. The skid and its attachment means cooperate to reduce handle vibration, eliminate certain resonance problems, and minimize vibrationally induced creep tendencies when the chain saw is resting on the ground with its engine idling.
