項記載の小型モータ。[Claims for Utility Model Registration] (1) Of the bearings at both ends in the axial direction that support the motor shaft, the motor shaft located on the output side is supported by a ball bearing, and the motor shaft located on the other side is supported by an oil-free metal. In a small motor where the end face of the motor shaft on the side opposite to the output shaft comes into contact with the bracket in the thrust direction, the outer ring of the ball bearing is fixed to a holder constructed in the frame and fixed to the shaft on the motor output shaft side. A small motor in which a coil spring is installed between the spacer of the preload receiving member and the inner ring of the ball bearing. (2) The spacer is a utility model consisting of a cup-shaped member with a concave gap in the center, and the center hole of the member is fitted and fixed to the motor shaft, and one end of the coil spring is buried in this gap. Scope of registration claims No. 1
Small motor described in section.
