ABSTRACT:
A portion of an oil path between an actuator for generating steering assistance power and a pump is formed by the inside space S in a housing covering an input shaft. A bearing assembly supporting the input shaft in the inside space has a bearing joined to one of the outer and inner circumferences of a circular spacer, and is inserted between the outer circumference of the input shaft and the inner circumference of the housing via radial clearances. The displacement of the bearing assembly toward one axial direction can be restrained by the contact between the contact portion formed on the other of the circumferences of the spacer and the receiving portion formed on either the housing or the input shaft, and the bearing assembly is pressed toward one axial direction by the oil pressure in the inside space.
