Abstract
A supporting structure of bearings incorporates a housing, a shaft on which a rotor is fixed, a first ball bearing supported on the housing supporting one side of the shaft and having an outer and inner race, a second ball bearing supported on the housing supporting the other side of the shaft and having an outer and an inner race, an elastic member for urging the outer race of the second ball bearing in the axial direction, and a ring spacer having at least one radial projecting portion disposed between the elastic member and the outer race of the second ball bearing. The outer race and the inner race of the first ball bearing are fixed to the housing and the shaft. The outer race of the second ball bearing is slidably mounted to the housing, while the inner race of the second ball bearing is fixed to the shaft. The ring spacer also includes an axial groove formed on the housing for receiving the radial projecting portion whereby the radial projecting portion slides along the axial groove.
