A saddled vehicle includes: a scavenge pump (121) fixed to a crankcase (29) and recovering oil in a crank chamber (41); and a link boss (167) formed at the crankcase (29) and holding a shaft element (166) to be rotatable about a swing axis (Sx) parallel to a rotation axis of a rear wheel, the link boss (167) coupling the crankcase (29) to the vehicle body frame. The scavenge pump (121) is disposed between the link boss (167) and the crankshaft (42) as seen in a side view of the vehicle. This provides a saddled vehicle including a scavenge pump that displaces by a smaller amount when a unit-swing type power unit swings.
