Abstract

Disclosed is a chainsaw capable of making it less likely that vibrations due to driving of an electric motor and a endless movement of a saw chain are transmitted to a worker, thereby enabling the worker to become less likely to be fatigued even in work using the chainsaw. The chainsaw includes an electric motor provided inside a body casing; a guide bar provided in a front portion of the body casing in such a manner as to protrude forwardly; a saw chain provided around an outer periphery of the guide bar in an endlessly movable manner, and configured to be endlessly moved along the outer periphery of the guide bar under driving of the electric motor; a handle section provided with respect to the body casing, and configured to be gripped by a worker; and an anti-vibration member interposed between the body casing and the handle section.
