Abstract
A planetary gear train is provided with: a carrier; a planetary gear; a planetary pin inserted into an insert hole provided through the planetary gear and coupled to the carrier to rotatably support the planetary gear; a thrust collar attached to a surface opposed to the planetary gear of the carrier so as to surround the planetary pin; and a pin for coupling the thrust collar to the carrier. The thrust collar has a first surface opposed to the carrier and a second surface opposed to the planetary gear, and has a first pin hole provided on the first surface so as not to reach the second surface. The carrier has a second pin hole on a surface opposed to the planetary gear. The thrust collar is attached to the carrier by inserting the pin into the first pin hole of the thrust collar and into the second pin hole of the carrier.
