Abstract

L'objectif de la présente invention consiste à améliorer la précision et la résistance d'une section filetée composée d'une résine, la section filetée supportant une tige d'enroulement de sorte que la tige d'enroulement se déplace dans la direction axiale de celle-ci. Un dispositif de store de fenêtre destiné à un véhicule est doté d'un store de fenêtre, d'une tige d'enroulement, d'une tige de support filetée qui est un exemple d'une tige d'une paire de tiges de support, et d'une tige de support côté pression. Un trou fileté est formé dans au moins une extrémité de la tige d'enroulement. La tige de support filetée se compose d'une résine, et une section filetée qui vient en prise avec le trou fileté et un trou central qui s'étend le long de l'axe de la section filetée sont formés dans la tige de support filetée. Une tige de renforcement est introduite dans le trou central. Un mécanisme de pressage qui presse la tige d'enroulement dans la direction d'enroulement se trouve au moins à une extrémité de la tige d'enroulement.
