Claims

[Scope of utility model registration request]

A motor in which a magnetic attraction force generated between a rotor to which one end of the motor shaft is fixed and a stator disposed opposite to the rotor acts in the thrust direction of the motor shaft, 2 in
Of the two positions, the part located on the rotor side is supported by a bearing metal, the other part is supported by a ball bearing, and a thrust receiving member whose one end surface contacts the inner ring of the ball bearing is fitted onto the motor shaft. A motor characterized in that the suction force in the thrust direction acting on the motor shaft is received at a contact point between the inner ring of the ball bearing and the thrust receiving member.
