Abstract

L'invention concerne un dispositif de disque permettant de réduire l'épaisseur d'un couvre-plateau et d'un support de plateau à une partie d'extrémité d'un plateau de disque, et de réaliser facilement l'assemblage du couvre-plateau et du support de plateau, le couvre-plateau étant peu susceptible de se détacher. Les nervures d'engagement des ressorts (50) ressortant d'un couvre-plateau (40) sont insérées dans les ouvertures rectangulaires (21b) formées dans une paroi avant (21) du support (20), et à l'arrière de la paroi avant (21), une partie enroulée (61) d'un ressort en fils (60) est fixée à une partie de fixation de ressort (29) du support (20) tandis que les deux extrémités du ressort en fils (60) sont engagées avec les nervures d'engagement des ressorts (50). Chacune des nervures d'engagement des ressorts (50) du couvre-plateau (40) est pourvue d'une partie de panneau parallèle dans une direction croisant la direction d'insertion dans les ouvertures rectangulaires (21), et la paroi avant (21) du support (20) est pourvue de parties d'attaches faisant face aux parties de panneaux parallèles des nervures d'engagement de ressorts (50) sur le bord des ouvertures rectangulaires (21b). La partie enroulée du ressort en fils (60) est insérée et fixée dans une partie de fixation de ressorts en forme de colonne (29) prévue sur la face arrière de la paroi avant (21) du support (20).
