In a handheld cutting machine that is constructed such that a user holds the machine by hand and performs cutting processing while moving the same, in which a lower portion of a circular cutting blade protruded from a lower surface side of a base that is placed on a cutting object is covered by a movable cover, an enough clearance is set between a supporting annular ring of a movable cover and a rotating boss portion of a bearing box in order to smoothly open and close the movable cover while a ring spring is interposed between the supporting annular portion and an axial restricting portion to increase dust-proofness of the a movable cover support portion.
