On the outer peripheral surface 16a of a cylindrical rib 16, convex parts 30 are formed in the middle portions between the portions in which radial ribs 18 adjoining each other are connected to the cylindrical rib 16. The cylindrical rib 16 is formed so that the thickness T in the radial direction thereof is decreased gradually from the base part 16c thereof toward the tip end part 16d.
