Abstract
Official abstract text for this publication.
A radial bearing is received in and is fixed to a bearing receiving portion of a yoke housing, which includes large and small diameter parts, to rotatably support a rotatable shaft. A thrust ball and a thrust plate are received in the bearing receiving portion on an axial side of the radial bearing, which is opposite from the rotatable shaft. The large diameter part receives and holds the radial bearing. The small diameter part holds the thrust ball. The thrust plate is held by an axial end area of the small diameter part.
