To provide a shearing machine for dismantling a large aircraft suitable for dismantlement of an aircraft such as a passenger aircraft with use of a strong aluminum alloy or the like.SOLUTION: A shearing machine for dismantling a large aircraft comprises: a tip blade into which a cutting edge entries into a shear object; a shear blade of a first jaw part comprising a pair of first parallel shear blades which are so located on blade width both sides as to be bent at an obtuse angle with respect to an entry direction of the tip blade, and a pair of second parallel shear blades which are so located on blade width both sides as to be bent at an obtuse angle with respect to a first parallel shear blade fitting part; and a shear blade of a second jaw part comprising a reception blade for those shear blades. The shearing machine comprises as the tip blade: a cutting edge blade comprising a small part, and a pair of tip taper blades, on both sides of the small part, where a blade width is gradually increased toward a rear end; and a pair of taper blades which are bent at an obtuse angle with respect to a fitting part of a rear end part of the tip taper blade, and are arranged over the first parallel shear blades.SELECTED DRAWING: Figure 1
