Claims

[Claims for Utility Model Registration] 1. A guide plate, an endless chain with blades, and a sprocket. The outer peripheral end surface of has a cross-sectional shape that can guide the inner peripheral side of the bladed chain, and the sprocket that can engage with the bladed chain is arranged at one end in the longitudinal direction of the guide plate, and the bladed chain is connected to the guide plate. In a chain saw, the tree restraining plate is wound around the outer circumferential end face of the guide plate and the sprocket, and the sprocket can be rotated by a drive mechanism. A chainsaw characterized in that the tree restraining plate has a restraining end face located on the outer peripheral side of the bladed chain. 2. The chainsaw according to claim 1, wherein the restraining end face of the tree restraining plate is arranged to form an acute angle with the elongated end face portion of the guide plate. 3. The chainsaw according to claim 1 or 2, wherein a plurality of tree restraining plates are provided on each long end surface portion of the guide plate. 4. The chainsaw according to claim 1, 2, or 3, wherein the chainsaw is provided so as to be able to change its posture on a traveling mechanism that can self-propel along the power distribution line while being supported by the power distribution line.
