Abstract: A rolling bearing of a balancer shaft device is positioned on an imaginary circle concentric with an axis of a shaft portion of a balancer shaft as viewed in a radial cross-section, and includes a cylindrical portion which covers the shaft portion. An outer circumferential surface of the cylindrical portion defines an inner ring raceway surface of an inner ring member on which a rolling element of the rolling bearing rolls. A part of the shaft portion of the balancer shaft, at a position on which the rolling bearing is disposed, has a cutout formed at a portion which does not contribute to offsetting of rotational vibration of a crankshaft.

Abstract: Blocks and inner rings of rolling bearings are arranged on the outer surface of a hollow shaft at predetermined intervals in the axial direction thereof. The outer surface of the hollow shaft is plastically deformed in its diameter enlarging direction so as to be press-fit to the inner surface of the blocks and inner surface of the inner rings of the rolling bearings. In this state, the blocks and inner rings of the rolling bearings are fixed to the outer surface of the hollow shaft.
