ABSTRACT:
The invention is directed to a motor-driven chain saw wherein a sprocket for a saw chain and a drive wheel for an oil pump are rotatably journalled on the crankshaft. The oil pump pumps oil for lubricating the saw chain and guide bar. The sprocket and the drive wheel are driven via a clutch drum. In this arrangement, a detachable resilient connecting member is provided to connect the drive wheel of the oil pump to the clutch drum at the peripheral wall of the latter. The resilient connecting member protects the drive wheel and the oil pump from excessive wear.
