Therefore, a fitting projection is provided in advance on a vehicle window glass. The fitting projection is fitted into a fitting hole provided in the opening frame portion, or the vehicle window glass and the opening frame portion are engaged with each other via a surface fastener.
Until the adhesive is solidified, a technique for temporarily fixing the adhesive stably has been proposed.

FIG. 6 is an explanatory diagram showing a conventional example (see Japanese Utility Model Publication No. 7-12115) in which the surface fastener is used in the above-mentioned temporary fixing method.

According to FIG. 1, a window glass 11 for a vehicle is used.
When the vehicle is mounted on the opening frame 1 of the vehicle, hook-and-loop fasteners 51 and 52 are previously attached to facing portions of the frame 13 integrally formed with the vehicle window glass 11 and the opening frame 1, respectively. Until the adhesive 3 solidifies and exhibits the required adhesive strength, the surface fastener 51,
52 are engaged with each other so that they can be temporarily temporarily fixed.
