PROBLEM TO BE SOLVED: To create an imbalance amount sufficient for the suppression of the vibration of an engine while securing compactness at mounting to the engine.SOLUTION: A balancer shaft which rotates integrally with a crankshaft of an engine, and suppresses the vibration of the engine comprises: a shaft part 1 which rotates around a shaft; an imbalance weight 2 which is constituted by combining divided weights 2a, 2b arranged at an external peripheral side of the shaft part 1 so as to be displaceable in a direction orthogonal to an axial direction of the shaft part 1; and an energization member 3 interposed between the shaft part 1 and the imbalance weight 2.SELECTED DRAWING: Figure 1 |
