Abstract

La présente invention a trait à un appareil de commande permettant de faciliter l'opération de montage de disques de friction sur une patte de fixation installée sur la carrosserie d'un véhicule. Les emplacements permettant de monter un premier disque de friction (6) et un second disque de friction (7) sont limités à la colonne extérieure (11) uniquement. Par conséquent, l'opération de montage du premier disque de friction (6) et du second disque de friction (7) en les plaçant l'un sur l'autre suivant une direction prédéterminée est extrêmement facile. Lorsque la colonne extérieure (11) subit un déplacement dans une direction télescopique, une tige de serrage (5) est contiguë à une rainure oblongue (72) du second disque de friction (7). Par conséquent, le second disque de friction (7) se balance avec une protubérance cylindrique (71) en tant que centre de balancement. La rainure oblongue (72) est formée de manière à être longue dans une direction d'ajustement de position de basculement. Par conséquent, la rainure oblongue (72) absorbe la différence entre la trajectoire du mouvement de balancement du second disque de friction (7) et la trajectoire du mouvement linéaire de la colonne extérieure (11). En conséquence de quoi, le second disque de friction (7) se balance sans à-coups, ce qui a pour résultat qu'il est possible d'ajuster sans à-coups la colonne extérieure (11) dans la direction télescopique.
