PROBLEM TO BE SOLVED: To provide a power transmission mechanism of a uniaxial crusher with which shock of a crushing rotor due to foreign matter is directly transmitted to neither a chain nor a reducer motor. SOLUTION: A sprocket attached to an output shaft of a driving motor and a sprocket assembly attached to a rotor shaft of the crushing rotor are wound around with a chain to transmit power of the driving motor, and thereby the crushing rotor having a movable blade is rotated and a matter to be crushed is crushed by the movable blade and a fixed blade. In the power transmission mechanism of the uniaxial crusher, a plurality of projection parts 10a projecting outside are formed at intervals at an outer periphery of a fixed ring 10 with which the sprocket assembly 6 is fixed to the rotor shaft, a cushion section 11 is held by the projection part 10a at a rear side in a rotation direction of the sprocket assembly 6, further the sprocket 12 is fitted on an outer periphery of the fixed ring 10 movably to the fixed ring 10 and a contact part 12a which extends to an axial center side and which is in contact with the cushion section 11 is formed at an inner periphery side of the sprocket 12.
