Abstract:
Provided is a vehicle window glass with which it is possible to reduce the quantity of duplicated images, curb the expression of glare on the upper edge side, which has outstanding esthetic properties or design characteristics. This vehicle window glass is mounted to a vehicle, and comprises laminated glass having a pair of glass sheets with chamfered edges; and an intermediate layer which bonds the pair of glass sheets. At least one of the pair of glass sheets has a cross-sectional shape in the vertical direction which is a wedge-shape in which the sheet thickness at the upper edge side is greater than the sheet thickness on the lower edge. With the laminated glass mounted to the vehicle at a predetermined mounting angle θ, the distance d on the upper edge side, between a lower virtual line DL drawn diagonally downwards from the lower boundary line between the glass sheet on the inside of the vehicle and the intermediate layer at an angle of arctan (1/2) with respect to the horizontal direction and an upper virtual line UL drawn from the upper boundary line between the glass plate on the outside of the vehicle and the intermediate layer at an angle of arctan (1/2) with respect to the horizontal direction falls within the range of 0.5 mm to 0.95 mm, inclusive.
