。[Claims for Utility Model Registration] (1) A crankshaft rotatably equipped with a chain drive sprocket, and a clutch mechanism fixedly attached to one end of the crankshaft to engage and drive the sprocket as necessary. , an oil pump drive mechanism disposed on the engine connection side at the other end of the crankshaft; and this oil pump drive mechanism are part of the structure, and a predetermined amount of lubricating oil is pumped into the chain by the operation of the oil pump drive mechanism. A chain saw comprising: a first rotating body that rotates the oil pump drive mechanism integrally with the sprocket; and a second rotating body for driving the pump connected to the rotating body. A dust seal mechanism is provided between the oil pump drive mechanism and the sprocket. A chain saw characterized in that a disc-shaped chain guide integrated with the chain drive sprocket is provided on the outer surface of the dust seal mechanism. (2) The dust seal mechanism is constituted by an annular dust seal member disposed and equipped on the sprocket side outer circumference of the first rotating body, and a cover member equipped on the entire outer periphery of the dust seal member. A chain saw that is characterized by:
