摘要： To provide a motor in which a rattle is hardly caused even if a bearing and a shaft are made of different materials, a motor includes a cylindrical motor case having a bottom, in a bracket which supports a press-fitted output shaft side bearing and closes an opening of the motor case. The motor further includes a ring member that is press-fitted to the bracket and is brought into abutment with the output shaft side bearing. The bracket and the ring member are made of the same material.

摘要： It is an object of the present invention to provide an electric power steering apparatus to be small and compact.The control housing 30 is installed between the motor housing 25 of the electric motor 18 and the gear housing 22. The ECU controlling the electric motor 18 is accommodated in the accommodating room S formed within the control housing 30. The motor housing 25 accommodates the bus bar 45 connected to the coil 44 of the stator 36, and the resolver 40 detecting the rotational position of the rotor 35. The rosolver 40 is installed within the bus bar mounting member 262 in inner side of radial direction. The partition 52 is mounted on the control housing 30 and the fixing screw 81 is engaged with the insulating member 84 by the way that the fixing screw 81 is inserted into insulating member 84 from its bottom surface side.
