ABSTRACT:
A drive shaft extends into a tubular member for use in a portable working machine. The drive shaft is mounted relative to the tubular member so as to undergo rotation relative to the tubular member. The drive shaft has a longitudinal axis and resin bushes integrally mounted on the drive shaft for rotation therewith at positions along the longitudinal axis corresponding to vibration nodes of the drive shaft. Each of the resin bushes has an outer peripheral surface disposed in slidable contact with an inner peripheral surface of the tubular member.
