PROBLEM TO BE SOLVED: To improve cutting capacity, by enabling linear and continuous cutting, by restraining a cutting object from slipping out from between cutters.SOLUTION: A cutter unit constitutes a hydraulic cutter, and comprises a pair of cutter arms opened-closed around a common shaft by driving force of the hydraulic cutter, and the pair of cutter arms can cross in closing, and the pair of cutter arms respectively comprise an arc-shaped inner peripheral edge for forming a cutting blade and an arc-shaped outer peripheral edge extending from the blade tip of the cutting blade, and the outer peripheral edge comprises a shape of becoming maximum in a distance to the center of the shaft in a midway part and reducing a distance to the shaft toward the blade tip from the midway part. Thus, a cutting object is restrained from slipping out from between cutters, and cutting capacity can be improved by enabling linear and continuous cutting. |
