PROBLEM TO BE SOLVED: To provide an intake manifold capable of easily externally inserting a bearing to a shaft through change of a simple structure.SOLUTION: A manifold body 12 has a common partition wall 12b positioned between mutually adjacent branch passages 14. In the partition wall 12b, a first insertion hole 21 to which a shaft 32 is loosely fitted is formed. In a peripheral wall 12a of the branch passage 14, a pair of second insertion holes 22 to which a cylindrical bearing 40 supporting the shaft 32 is press-fitted are formed. In the shaft 32, a taper part 32a of which the outer peripheral surfaces of both end parts are formed into a tapered shape is formed. |
