Abstract
In a motorcycle in which an engine unit is mounted to a motorcycle body and a power transmission unit coupled to the engine unit is arranged to the motorcycle body to be swingable through a pivot shaft, a rear wheel suspension system is formed so as to include the power transmission unit, a pair of arm members disposed to lateral side portions of the motorcycle body in parallel to each other, and connection members connecting both end portions of the arm members. One of the arm members constitutes the power transmission unit which has an inner hollow portion in which a power transmission member is accommodated and has a structure dividable into lateral two parts forming an arm base section and a cover section.
