Abstract

PURPOSE: To decrease bending stress generated at a motor shaft and prevent one- sided contact between a pinion and the internal groove of a ball race by a mechanism wherein a shaft end of a motor is supported by means fo a bearing.
CONSTITUTION: A shaft end of a motor for turning is supported by means of a bearing 17 immersed in lubricating oil for pinion 15, and a cover 18 is fixed to a motor case 13. Thus, the desired effect can be obtained.
