摘要：
An electric power assisting steering apparatus comprises a housing, a motor mounted on the housing to generate auxiliary steering power in a rotating shaft, an output shaft to transmit the steering power for steering the wheels, a bearing for supporting the output shaft to be freely rotatable, and a worm gear mechanism having a worm connected to the rotating shaft and a worm wheel connected to the output shaft, to transmit the auxiliary steering power of the motor to the output shaft. An elastic body is provided between at least one of the rotating shaft and the housing and the bearing, so that when a tooth surface of the worm and that of the worm wheel are brought into contact with each other, the rotating shaft is moved in at least one of the axial direction and the radial direction relative to the housing by deforming the elastic body.
