Claims (1)
に対して回転可能に支持したモータの軸受構造に
おいて、上記回転軸の端部と当接する位置決め部
をモータのロータケースに設け、軸線方向に摺動
可能な上記一対の転がり軸受の内輪と上記ロータ
ケースとの間に軸線方向に伸縮可能なばねを介装
したことを特徴とするモータの軸受構造。 In a motor bearing structure in which a rotating shaft is rotatably supported with respect to a housing by a pair of rolling bearings, a positioning part that comes into contact with the end of the rotating shaft is provided in the motor rotor case so that it can slide in the axial direction. A bearing structure for a motor, characterized in that a spring that can be expanded and contracted in the axial direction is interposed between the inner ring of the pair of rolling bearings and the rotor case.
