PROBLEM TO BE SOLVED: To solve the problem that the axis of a crankshaft received in bearing device moves in the case the crankshaft is light and drilled by an unbalance correction device installed onto a dynamic balancing machine. SOLUTION: The unbalance correction device 6 can be installed onto the dynamic balancing machine for the crankshaft having a plurality of bearing devices 3, 4, 5, that are allocates at determined journals 20a, 20b, 20c of the crankshaft to be tested and support the axis of the crankshaft. The unbalance correction device 6 includes a material removing device 7 and a fixing device 8 that fixed the crankshaft into the bearing devices while a portion of the crank of the crankshaft is removed by the material removing device 7 so as to correct the unbalance. The fixing device 8 includes a grasping arm 9, and the end of the grasping arm 9 forces the journal 20b down into the bearing device 4 from above obliquely, thereby the crankshaft is fixed into the bearing device.
