PROBLEM TO BE SOLVED: To improve assembling property of a fuel delivery pipe disposed under a surge tank for an intake device of a V-type engine, and facilitate manufacturing, and to secure the sealability of an inlet pipe without providing a fastening bolt on the inside part of the surge tank, omit a fastening bolt, simplify the structure and reduce in weight. SOLUTION: In the V-type engine, an intake system structure is composed of the surge tank and a first and a second inlet pipes, the intake structure is disposed on divided surfaces which are parallel to each other and under the surge tank by being divided into an upper block which is constituted of the surge tank and a first and a second upper pipe parts of the first and the second inlet pipes and a lower block which is constituted of a first and a second lower pipe parts of the first and the second inlet pipes. A first and a second sealing parts which surround the first and the second inlet passages are provided on the divided surface of the upper block. A first and a second linear inside sealing surface parts are provided by molding in positions directing to insides of a first and a second engine banks within the first and the second sealing parts. Only the first and the second linear inside sealing surface parts are disposed under the surge tank.
