<p>The present invention provides a device for correcting an unbalance of a propeller shaft (A), specifically an unbalance correction device of a propeller shaft capable of securing a considerable amount of correction, reducing the generation of noise and the like, and preventing the adverse effect of welding heat caused by welding and fixing the balance weight from exerting on a vibration absorbing rubber member. The unbalance correction device of a propeller shaft (A) is configured from a propeller shaft to which a damper (3) is mounted, and a balance weight (B) in which a primary weight plate part (5) and an auxiliary weight plate part (6) are formed continuously and integrally along a longitudinal direction, and a protruding piece (51) is protrusively formed on a concave arced surface on a rear surface side of the primary weight plate part and from each corner part at four locations. The primary weight plate part (5) is disposed in a non-mounted area of the damper (3) at an axial direction end of the outer shaft with a longitudinal direction of the balance weight coinciding with an axial direction of the outer shaft, and the balance weight (B) is configured such that only the protruding piece comes in contact with and is welded to an outer peripheral side face of the outer shaft.</p> |
