Abstract

PURPOSE:To bond a window glass to a car-body surely by increasing the bonding area of at least lower part out of the total bonding area of the window glass to the car-body. CONSTITUTION:When a bonding agent 90 is spread on the back side of a window glass 5 by a bonding agent spray gun 31, the bonding agent 90 is spread wavelikely and continuously, as shown by a mark 100, in the case of spreading the bonding agent on the lower part (front end part) 44 of the window glass 5. Thus, on the lower part 44 of the window glass 5, a bonding area is increased so that the bonded status between the lower part 44 of the window glass 5 and the front part of a vehicle can be secured. Therefore, even if an engine is moved backward in the case of the collision of the automobile, the lower end 44 of the window glass 5 is hardly peeled off from the front part of the vehicle and the possibility of coming off of the window glass 5 from the front part 40 of the vehicle becomes small.
