V-engine air intake structure

A V-engine air intake structure comprising a first cylinder and a second cylinder that are arranged mutually inclined or perpendicular when viewed in a crankshaft direction, wherein the first cylinder has a first throttle body mounted on a cylinder side surface on a side opposed to the second cylinder, and the second cylinder has a second throttle body mounted on a cylinder side surface on a side opposed to the first cylinder, the first throttle body includes a first valve rotation device that drives a first throttle valve, and the second throttle body includes a second valve rotation device that drives a second throttle valve independently of the first valve rotation device, and the first throttle body and the second throttle body are arranged such that the first and second valve rotation devices have states rotated around bore central axes to cause respective throttle valve rotation shafts forming angles with respect to reference lines, wherein the reference lines are parallel to a crankshaft in an engine top view, wherein the second cylinder has a cylinder axis line shifted to one side with respect to a cylinder axis line of the first cylinder.
