To surely fix a car body panel and a neck part to each other by providing the neck part formed of synthetic resin, and integrally forming an outward flange for fixing the neck part to the car body on the outer periphery of the neck part.
Outward flanges 41a, 41b formed like a rhomboid in appearance are provided around the outer cylinder part of the upper end of a neck part 4. Fit-in parts 42a, 42b V-shaped in section, in which the circumferential end for forming an opening 21 of a car body panel 2 is fitted are formed on the outward flages 41a, 41b. Further, a bolt fixing hole 8b is formed in the outward flanges 41a, 41b, in such a manner that when the neck part 4 is fitted in the opening 21 of the car body panel 2, it corresponds to a bolt fixing hole 8a. The lower end part 61 of the neck part 4 and the upper end part 62 of the filter tube main body 1 are joined to each other by welding or bonding to be united in a body.
