Abstract

L'invention porte sur un support supérieur dans lequel il n'est pas nécessaire de découper la surface périphérique extérieure d'une monture intérieure pour fixer une monture anti-rebond, le coût de fabrication du support supérieur peut être réduit, une opération d'emboutissage peut être effectuée facilement par une petite force et la monture anti-rebond peut être fixée rigidement à la monture intérieure dans la direction de la rotation. Dans le support supérieur disposé entre une carrosserie de véhicule et un pare-chocs, ce qui empêche les vibrations au moyen de la déformation élastique d'un élément élastique en caoutchouc, des pièces de monture saillantes (58) sont disposées partiellement sur la surface d'extrémité supérieure d'une monture intérieure (12) dans la direction circonférentielle et sont en saillie vers le haut sur une longueur supérieure à l'épaisseur d'une monture anti-rebond (18), et des parties en renfoncement (66) correspondant aux pièces de monture saillantes (58) sont disposées dans la monture anti-rebond (18). Pendant que les pièces de monture saillantes (58) sont insérées de bas en haut et ajustées sur les parties en renfoncement (66), les parties des pièces de monture saillantes qui sont exposées sur la surface supérieure de la monture anti-rebond (18) sont repliées et serties pour fixer la monture anti-rebond (18) à la partie supérieure de la monture intérieure.
