Title:
LIGHT SCANNING MOTOR
Document Type and Number:
Japanese Patent JPS61177139
Kind Code:
A
Abstract:
PURPOSE:To reduce the size of a motor by mounting an elastic retaining member for retaining one end of an elastic member for prepressurizing a bearing on the axial perpendicular surface formed on the end of a rotational shaft, thereby reducing the size of bearing prepressurizing means. CONSTITUTION:When prepressure is applied from axially to a bearing in which inner races 3a, 4a are mounted in a rotational shaft 10 and outer races 3b, 4b are mounted on an immovable member 2, an elastic retaining member 80 is clamped by a screw 60 to the axial perpendicular surface formed on the end of the shaft 10. A leaf spring 7 is interposed between the member 80 and the inner race 4a, axial prepressure is applied to the bearing. Thus, the member 80 can be compactly formed to reduce the entire size of a motor.
