Summary:PROBLEM TO BE SOLVED: To make a device small and simple by integrally combining a rotating drum driving means with rotating drums in such a way as to be formed into one transmission system. SOLUTION: In this shearing machine, an upper rotating drum and a lower rotating drum 13 and 14 having shearing blades 13a and 14a at their outer circumferential parts are supported on bearing frames 12 by way of eccentric sleeves 15 and 16, only the upper rotating drum 13 is made rotatable by a driving motor 17, and concurrently, the respective rotating drums 13 and 14 can be mutually approached to/separated from by rotating the eccentric sleeves 15 and 16 by a driving motor 25. Interlocking gears 29 and 30 are fixed to the shaft end parts of the respective rotating drums 15 and 16 in such a way as to be interlocked with the rotating drums when both the rotating drums 15, 16 come close together, and concurrently, the interlocking gears 29 and 30 are connected to synchronizing gears 33 and 34 by means of Oldham's joints 41 and 42 in order to be synchronously rotated regardless of an approaching time or a separating time.
