Abstract
The center of gravity of a retaining pin which is struck into a retaining-pin receiving hole to join a rotor barrel with a rotor shaft is eccentrically positioned toward the leading end of the pin beyond the axis of the shaft so that upon rotation of the rotor, the pin is forced to thrust toward the bottom of the hole by the centrifugal force, thereby preventing the pin from pulling out of the hole.
