Abstract
A power train includes a driving shaft and a follower shaft connecting to the driving shaft by way of a first joint. The follower shaft is adapted to slide relative to the driving shaft in an axial direction. The follower shaft includes: a holder shaped substantially into a cylinder, and a tubular shaft section coupled with the holder in the axial direction. The first joint includes a member defining an outer diameter. The holder holds therein the member of the first joint. The tubular shaft section coupled with the holder in the axial direction causes an inner curl to a second joint coupling the holder and the tubular shaft section. The inner curl defines an inner diameter greater than the outer diameter of the member of the first joint.
