Abstract
An oil tank (431) for storing oil for lubricating a saw chain (21) and a fuel tank (443) for storing fuel for an engine (5) are integrally formed with a top handle (41) provided on an upper side of a body (3). The body (3) and the top handle (41) are connected by a connecting spring such that vibration transmission from the body (3) to the top handle (41) is restrained. In other words, since the heavy oil tank (431) and the weighty fuel tank (443) are integrally formed with the top handle (41) to trim the weight of the body (3) that generates vibration, vibration transmitted to the top handle (41) is decreased to improve the vibration insulation of a chain saw (1).
