An unbalance correction device of a high speed rotary apparatus which can prevent the lowering of productivity in the production line of a high speed rotary apparatus while reducing variation in the posture of a workpiece supported by a jig and suppressing vibration of a member (clamp member) for securing the workpiece to the jig, and can enhance the precision of unbalance correction. The unbalance correction device (1) of a high speed rotary apparatus includes a plurality of claw structures (10) (clamp members) for fixing, by clamping, a workpiece (20) to a turbine housing section (3); a cylinder mechanism (30) for moving and energizing the claw structures (10), a solenoid valve (35) for adjusting the moving amount and energizing force of the claw structure (10) by the cylinder mechanism (30); a position sensor (37) for detecting the position of the claw structure (10); and posture control means for controlling each solenoid valve (35) such that the position shift of the claw structure (10) detected by the position sensor (37) becomes smaller than its acceptable value. |
