摘要： 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.

摘要： A step portion is formed at an outer peripheral surface of an axially-central portion of an outer ring, and is smaller in diameter than outer peripheral surfaces of axial opposite end portions of the outer ring. The step portion is continuously formed over an entire periphery of the outer ring, and has a predetermined width over the entire periphery. The outer peripheral surface and inner peripheral surface of the outer ring are pressed radially inwardly, and therefore are bulged radially inwardly into a step-like shape to form the step portion having an axis coinciding with a axis of the outer ring. A pedestal of a cylinder block and a cap member retain the outer peripheral surface of the step portion, thereby positioning the outer ring in the axial direction and also preventing a movement of the outer ring in the axial direction.
摘要翻译：在外圈的轴向中央部的外周面形成台阶部，其直径比外圈的轴向相对端部的外周面小。台阶部分在外圈的整个周边上连续地形成，并且在整个周边上具有预定的宽度。外圈的外周面和内周面被径向向内挤压，因此被径向向内凸出成阶梯状，以形成具有与外圈的轴线重合的轴的台阶部。气缸体和盖构件的基座保持台阶部的外周面，从而将外圈沿轴向定位，并且还防止外圈沿轴向移动。
