Abstract
A device that is able to reduce the variation in the clearance between the upper and lower blades and of which the clearance adjustment operation is simple. The work cutting apparatus has a freely rotating ram mounted with an upper blade. An axial direction pressure application means that prevents any play in the axial direction at the bearing being the rotating pivot of this ram by the application of pressure is arranged. The axial direction pressure application means applies pressure in the axial direction to the inner wheel of the bearing via the spacer by a cylinder attached to the rotating support shaft and pressurizes the bearing. The pair of upper and lower blades each form an approximate L-shape and the rotating support shaft is positioned such that it is at an angle within the horizontal plane with respect to each side of the upper and lower blades.
