GLASS RUN

A glass run includes a body part including exterior and interior side walls and a bottom wall connecting the exterior and interior side walls; an exterior lip projecting from the exterior side wall toward the bottom wall and configured to slidably contact an exterior side of a door glass; and an interior lip projecting from the interior side wall toward the bottom wall and configured to slidably contact an interior side of the door glass. The interior lip includes a base end portion extending toward the bottom wall and is curved to be oriented toward an exterior of the vehicle as extending to its distal end portion, and the interior side wall includes a protuberance protruding toward the exterior, and the protuberance is positioned to be able to contact the interior lip when the interior lip is pressed toward an interior of the vehicle by the door glass to deform.
