Abstract
A saddle riding type vehicle capable of making turns by leaning a vehicle body includes a pair of rear wheels provided at opposite sides of the vehicle body, a pair of support mechanisms arranged to support the pair of rear wheels to be movable, independently of each other, up and down about a pivot axis relative to the vehicle body, an engine disposed forward of the pivot axis to produce a drive force, a differential mechanism arranged to distribute the drive force of the engine to the pair of rear wheels and to absorb a rotating speed difference between the pair of rear wheels at a time of making a turn, the differential mechanism including drive shafts arranged between the engine and the pivot axis, a pair of shaft drive mechanisms provided for the pair of rear wheels, respectively, and arranged to transmit the drive force of the differential mechanism to the pair of rear wheels, and a pair of constant velocity universal joints provided for the pair of shaft drive mechanisms, respectively, each including a pair of universal joints connected by a coupling yoke, the coupling yoke being located on the pivot axis, and the pair of universal joints being arranged in a positional relationship of point symmetry.
