A cylindrical part 17A of the flanged resin bush 17 is fitted into an inner circumference side of the metal bush 15. An annular flange part 17B of the flanged resin bush 17 is inserted between an outside link part 13 and the metal bush 15, and between the outside link 13 and an inside link part 14 to position the cylindrical part 17A in the metal bush 15 in an axial direction.
