Abstract

Construction of door glass runs in a motor vehicle, wherein: there are provided vertical side glass runs and a top side glass run, which are secured to vertical sides and a top side of a door frame, respectively, in vehicle door with the door frame; the vertical side glass runs slidably guide a forward end sliding portion of a slider in the opening or closing direction of a door glass and restrain the forward end sliding portion in the direction of thickness of the door glass, the slider is mounted to end edges of the door glass in the longitudinal direction thereof, and, has the forward end sliding portion shifted into a compartment and being of a crank shape in cross section; and the top side glass run has an inner lip for contracting the inner surface of a top end edge of the door glass to seal when the door glass is fully closed; the inner lip in the top side glass run is decreased in cross section thereof toward the vertical side glass runs within a range of contacting the slider when the door glass is fully closed, made gradually thinner at the distal ends thereof in wall thickness than the other general portion thereof and thicker at the proximal ends thereof in wall thickness than the other general portion thereof.
