Abstract

PURPOSE: To reduce the number of parts, by using a multi-purpose bearing body, the bottom of a closed end of a shaft insertion hole being used as a thrust bearing, the inner circumference of the hole as a radial bearing and the open end of the hole being formed as a radial bearing.
CONSTITUTION: The bottom 7b of a closed end of shaft insertion hole 7a, made on a bearing body 7 for a brushless motor, is used as a thrust bearing and a stepped portion 7c of its inner circumference is used as a radial bearing, while its open end is equipped with a radial bearing 8. Since most of lateral pressure, caused by a flat belt to a revolving shaft 1, acts on the radial bearing 8, the stepped portion 7c having a function of radial bearing is sufficiently wear-proof with little negative lateral pressure. This holding device, composed of the solid bearing body 7 and a single unit of radial bearing 8, can reduce the number of parts required and its manufacturing cost.
