PROBLEM TO BE SOLVED: To reduce sucking resistance in an intake air passage in an intake air passage structuring section, and to easily improve engine output, in a vehicular V-type engine intake device wherein a pair of fore-and-aft banks is disposed in a V-shape on a flat surface orthogonal to an axis of a crank shaft, and wherein the intake air passage structuring section equipped with at least a throttle body and independently corresponding to each cylinder is disposed between both banks and connected to inner surfaces of a cylinder head. SOLUTION: A plurality of throttle shafts 33A, 33B rotatably supported by throttle bodies 34A, 34B is coaxially disposed so as to intersect the axis C of the crank shaft in a plane view. Center lines CLA, CLB of the intake air passages 40A, 40B respectively formed by the intake air passage structuring sections 31A, 31B are disposed on a straight line orthogonal to the axes of the throttle shafts 33A, 33B in the plane view.
