摘要

A planetary gear train is provided with a planetary gear and a planetary pin inserted into the planetary gear. The planetary gear includes: a gear member having teeth on the outer face and a through hole; an intermediate housing inserted into the through hole and having an insert hole into which the planetary pin is inserted; and a plurality of sliding bearing members jointed onto the insert hole of the intermediate housing. The plurality of sliding bearing members form a sliding bearing which sustains the planetary pin and the planetary gear to be rotatable with each other.
