A weather-strip-equipped vehicle body structure comprising: a door opening member forming a door opening of a vehicle body; a door for opening and closing the door opening; and a weather strip for sealing between the door opening and the door when the door is closed, wherein the door opening member includes: an outer panel positioned on a side facing a vehicle exterior; an inner panel positioned closer to a vehicle interior than the outer panel, the outer panel includes: a flange joined to the inner panel for forming the door opening; and an adhesion surface, for which the weather strip is positioned at an adhering position of the outer panel, positioned farther away from the door opening than the flange and proximately to the vehicle exterior for allowing adhesion of the weather strip thereto, and the outer panel has, between the adhesion surface and the flange, a projecting surface projecting substantially perpendicularly to the adhesion surface, characterized in that an extension line of the projecting surface is maintained at an acute angle (θ7) relative to a window glass pane, and the adhesion surface is inclined at an obtuse angle of inclination (θ1) relative to the flange, whereby the weatherstrip is pressed against the projecting surface when positioning the weatherstrip at the adhering position. a door opening member forming a door opening of a vehicle body; a door for opening and closing the door opening; and a weather strip for sealing between the door opening and the door when the door is closed, wherein the door opening member includes: an outer panel positioned on a side facing a vehicle exterior; an inner panel positioned closer to a vehicle interior than the outer panel, the outer panel includes: a flange joined to the inner panel for forming the door opening; and an adhesion surface, for which the weather strip is positioned at an adhering position of the outer panel, positioned farther away from the door opening than the flange and proximately to the vehicle exterior for allowing adhesion of the weather strip thereto, and the outer panel has, between the adhesion surface and the flange, a projecting surface projecting substantially perpendicularly to the adhesion surface, characterized in that an extension line of the projecting surface is maintained at an acute angle (θ7) relative to a window glass pane, and the adhesion surface is inclined at an obtuse angle of inclination (θ1) relative to the flange, whereby the weatherstrip is pressed against the projecting surface when positioning the weatherstrip at the adhering position. an outer panel positioned on a side facing a vehicle exterior; an inner panel positioned closer to a vehicle interior than the outer panel, the outer panel includes: a flange joined to the inner panel for forming the door opening; and an adhesion surface, for which the weather strip is positioned at an adhering position of the outer panel, positioned farther away from the door opening than the flange and proximately to the vehicle exterior for allowing adhesion of the weather strip thereto, and a flange joined to the inner panel for forming the door opening; and an adhesion surface, for which the weather strip is positioned at an adhering position of the outer panel, positioned farther away from the door opening than the flange and proximately to the vehicle exterior for allowing adhesion of the weather strip thereto, and the outer panel has, between the adhesion surface and the flange, a projecting surface projecting substantially perpendicularly to the adhesion surface, characterized in that an extension line of the projecting surface is maintained at an acute angle (θ7) relative to a window glass pane, and the adhesion surface is inclined at an obtuse angle of inclination (θ1) relative to the flange, whereby the weatherstrip is pressed against the projecting surface when positioning the weatherstrip at the adhering position.
