Disclosed is a sawdust discharge port which is arranged such that a side wall of a cover member covering a body frame of a chain saw and opened at its lower end and forming one of the constituent elements of the discharge port has a substantially flat outer surface, and an inner surface forming an inclined surface whose lower end edge portion is gently inclined inwardly and downwardly, thereby to permit the side wall to gradually increase in thickness toward its lower end.
