Abstract: In a structure for fixing a window glass to a window opening edge of a vehicle body, providing: an adhesive for bonding an outer periphery of the window glass to a glass receiving surface in the window opening edge of the vehicle body; and a dam mounted on an inner surface of the window glass along the adhesive for preventing the adhesive from projecting inwardly, in which the dam includes: a first recess formed at a first middle part of a side surface of the dam, to make the first middle part thinner than an upper surface of the dam; a second recess formed at a second middle part of a bottom surface of the dam where the dam contacts the glass receiving surface; and a pair of legs formed on both sides of the second recess, the dam can be smoothly bent along the corner of the window glass, with a less inclination thereof and a little deformation of the cross sectional configuration thereof.
