A window glass can be accurately and preferably mounted by correcting a displacement of a curved surface shape of the window glass in the crosswise direction even when there is a displacement of the curved surface shape of the window glass in the crosswise direction. A slit laser beam is irradiated with from slit laser beam irradiators 12c and 12d across the right and left ends of the window glass 6, the circumference of a window glass mounting opening 8, and a windshield pillar section 11; rotation adjustment of the window glass 6 is performed, based on a processed image obtained by image processing of images, which have been photographed with a CCD cameras 10c and 10d, of the slit laser beams, in such a way that clearances in the pressing direction at the right and left ends of the window glass 6 are the same as each other; and the window glass 6 is pressed onto a window glass mounting surface on the circumference of the window glass mounting opening 8 for mounting onto the surface.

L'invention concerne un mécanisme de fixation appropriée d'une vitre avec grande précision même si la forme de la surface latérale courbe de la vitre n'est pas homogène, par correction de la non-homogénéité. Un faisceau de lumière fendu est appliqué de manière oblique par des organes d'irradiation par laser (12c, 12d), de manière que le faisceau traverse les parties terminales droite et gauche de la vitre (6), la périphérie d'une ouverture (8) de fixation de la vitre et une partie montant avant (11). Une image du faisceau lumineux est ensuite photographiée par des caméra CCD (10c, 10d) et traitée. En fonction de l'image traitée, la vitre (6) est ajustée en rotation, de manière que les espaces dans le sens de pression aient la même taille au niveau des parties terminales gauche et droite de la vitre (6), laquelle est ensuite poussée contre la face de fixation entourant l'ouverture (8) permettant la fixation de la vitre avant sa fixation en place.
