Abstract
A chain saw with vibration-isolating devices, capable of providing a desirable vibration-isolating effect over a wide frequency range and reducing accidental deviation from a desired cutting line in a cutting operation. The chain saw includes a main body containing an engine, a frame member mounting a grip handle thereon, and at least two vibration-isolating devices each interposed between the main body and the frame member to support the main body with respect to the frame member. Two of the vibration-isolating devices are disposed spaced apart from each other in the longitudinal direction of the chain saw. Each of the two vibration-isolating devises includes a pair of first and second vibration=isolating members which are different in frequency range for providing a vibration-isolating effect. The two vibration-isolating devices are disposed such that the respective first or second vibration-isolating members are positioned in a first or second diagonal relationship with respect to one another.
