A window molding is easy to install, and the installed state remains stable and the external appearance is superior, and does not show floating or generate abnormal noise during highspeed cruising and is able to be flush-surfaced easily. The window molding (4) is constituted by: a molding body (4a) attached along a space between a window plate (3) and a body panel (2); a protruding rib (4b) protruding from the molding body (4a) towards an external surface of the window plate (3); a leg section (4c) extending from the molding body (4a) towards the space (5); a sealing lip (4e) extending from the molding body (4a) towards an external surface (2a) of a body panel (2); a linking lip (4f) extending from the leg section (4c) towards the space-forming surface (2a) of the body panel (2) and linking with a tip of the sealing lip (4e) or in a vicinity of the sealing lip (4e) to form a hollow section (6). <IMAGE>
