Abstract
A glass run of the invention includes a furrow part on which a window glass moves and slides. The furrows of the furrow part are inclined at a predetermined angle with respect to the sliding direction of the window glass. When dirt or dust is deposited in between the window glass and the furrow part, it enters the furrows of the furrow part. The slanted configuration of the furrows of the furrow part, in combination with the sliding force of the window glass, moves dust or dirt along the furrows to a position where the dirt does not rub against the end face of the window glass. The structure of the invention keeps the window glass from undesirably rubbing dust or dirt, thus preventing an increase in sliding resistance and undesirable noise.
