BRUSHLESS DC MOTOR AND MOTOR-DRIVEN POWER STEERING DEVICE INCLUDING THE SAME

PROBLEM TO BE SOLVED: To resolve the problem of a bearing for retaining a rotor being forcibly inserted in a bearing holding part in a cylindrical motor case in the conventional brushless DC motor, with the working being difficult, reassembling being impossible and connection work of a lead from a stator being difficult. SOLUTION: A motor housing 7 is constituted of a first and a second divided bodies 8, 9, which are divided into an upper body and a lower body along a rotary shaft 3. Bearings 15, 16, engaged with end portions of the rotary shaft 3 penetrating the rotor 12, are pinched between bearing holding parts 22a, 22b and 23a, 23b of both of the divided bodies 8, 9. When the divided bodies 8, 9 are combined, a lead 14 of a stator 13 is protruded in an accommodating part 17 for a substrate 6 through an aperture 19.
