とする円切りコンパス。[Claims for Utility Model Registration] A magnet whose suction surface is fixed to a material to be cut by adsorption, a beam whose proximal end is supported by the magnet so as to be rotatable around the magnet, and this beam. In a circular compass comprising a holder provided at the tip of a beam and holding a torch, etc., a recess is formed in the attracting surface of the magnet, and a center pin having a conical tip is inserted into the recess. The center pin is inserted so as to be movable in the axial direction so as to be aligned with the rotation center of the beam, and the center pin is provided with a biasing member that biases the center pin toward the suction surface and causes the tip to protrude toward the suction surface. A circular compass featuring
