PURPOSE:To obtain a stopper mechanism which exhibits the effective displacement restraining function by providing an outer cylindrical fitting with a through window, providing stopper rubber and a cylindrical member, and thereby pushing stopper rubber into a cavity by the use of the cylindrical member. CONSTITUTION:In an integrally vulcanized and molded article 18, stopper rubber 46 which is projected outside for positioning through the second window section 30 of an outer cylindrical fitting 12, is pressed at its projected end face by a mounting cylindrical fitting 16 when the mounting cylindrical fitting 16 is outwardly fitted or fixed to the integrally vulcanized and molded article 18. This thereby causes stopper rubber to be pressed in a cavity 20. This thereby causes stopper rubber 46 to be projected into the cavity 20 side by the amount pushed in. When stopper rubber 46 is projected into the cavity 20 side, the inside dimension of the cavity 20 is compressed so as to be smaller than the integrally vulcanized and molded article 18, stopper rubber 46 is brought into contact with the inner circumferential surface of the cavity 20 at an inner cylindrical fitting side with stopper rubber pushed in by the mounting cylindrical fitting 16. |
