Abstract: A rear wheel suspension device of a motorcycle has rear end portions of an upper arm member and a lower arm rotatably joined to a knuckle member, which pivotally supports a rear wheel. The rear wheel suspension device can obtain a progressive cushion property while avoiding an increase in the number of parts. At the same time, the rear wheel suspension device can make the acquisition of extra rigidity of the vehicle body frame unnecessary. One end of a rear cushion unit is joined to one of an upper arm member and a lower arm member. A rear end portion of another of the upper arm member and the lower arm member is rotatably joined to a knuckle member in front of a rear wheel support portion of the knuckle member. Another end of the rear cushion unit is joined to one of another arm member and knuckle member.
