面ガード機構。[Scope of Claim for Utility Model Registration] A rotary cutter object in which a cutter having a side edge and a lower edge is attached to a cutter head fixed to the lower end of a vertical axis of rotation so as to rotate in a plane parallel to the floor. The floor of a rotary blade object characterized in that a guard body is provided on the rotation center line of the bottom surface of the cutter head, projecting slightly further downward from the lower blade edge projecting below the bottom surface of the head and contacting the floor surface with minimum frictional resistance. Face guard mechanism.
