Patent abstract

An intake system has an intake pipe, a passage member which is inserted into a peripheral wall of the intake pipe in a radial direction to form an intake passage passing across a front end and a rear end thereof in a direction of insertion along with the intake pipe, a seal member which is arranged at a seam between the peripheral wall of the intake pipe and the passage member and seals the seam, and an elastic member which is made of the same material as that of the seal member and is interposed between the peripheral wall of the intake pipe and the front end of the passage member so as to be capable of giving the front end of the passage member an elastic reaction force in a direction perpendicular to the axis of the direction of insertion.
