Document Type and Number:
Japanese Patent JP2561074
Kind Code:
Y2
Abstract:
A motor case end plate structure, comprising: a motor case accommodating a motor unit therein and provided with a first radial bearing for a rotor shaft of the motor unit; a radial flange provided at an open end of the motor case; and an end plate, made of molded synthetic resin, having a second radial bearing for the rotor shaft and adapted to be attached to the motor case by way of the flange; the end plate being provided with at least three separate peripheral mounting surfaces disposed around the rotor shaft and projecting from surrounding parts so as to substantially directly abut an outer end surface of the flange of the motor case. Thereby, any error in the planeness of the mounting surfaces or any error in their perpendicularity with respect to the axial line of the motor unit can be readily corrected by shaping the part of the die for molding the end plate corresponding to the mounting surface to be corrected without requiring excessive cost or time. Thus, an exact alignment between the motor case and the end plate can be accomplished in an economical fashion.
