[Problem] To provide a small-sized saddle riding vehicle and a rigidity adjustment device of a body frame of a vehicle which can effectively displace a body frame and the like so as to assist movement of a suspension device such as a suspension mainly against a force in a jolting direction from a road surface. [Solution] In a rocking vehicle 10, a front wheel suspension device 12 suspends a front wheel 13 in an upwardly displaceable manner due to a reaction force from a road surface. The rocking vehicle 10 includes a cushion support arm 64, on a body frame 11 side, including a cushion support portion of the front wheel suspension device 12, and a rigidity adjustment device 90 which is extended between plural portions of the cushion support arm 64. The rigidity adjustment device 90 applies a pre-tension to the cushion support arm 64, and the pre-tension generates a pre-force component in the cushion support portion in the same direction as the upward moving direction of the front wheel 13 due to a reaction force of the front wheel 13 from the road surface.
