Swing arm structure with shaft drive and spacer

摘要

To provide a rear wheel structure which can easily perform the mounting and dismounting of a rear wheel without causing a fluctuation in a banking angle. In the rear wheel structure which includes a pair of left and right swing arms which are arranged to sandwich a rear wheel, a driving force transmission device is provided for transmitting a driving force to the rear wheel along one swing arm, and a spacer which is arranged on an axle of the rear wheel. A muffler is arranged outside the swing arm on a side opposite to the driving force transmission device. The spacer is arranged between the swing arm on the driving-force-transmission-device-side and the rear wheel for mounting the rear wheel relative to the one swing arm.
