A garnish has an upper mounting projection concealed by a corner pad and a lower mounting projection concealed by a lower end of a vertical sash portion. The upper mounting projection is mounted in an upper mounting hole of the vertical sash portion. The lower mounting projection is mounted in a lower mounting hole of an outer panel. The upper mounting hole is concealed by the corner pad, and the lower mounting hole is concealed by the lower end of the vertical sash portion. This ensures a high quality appearance of the garnish without employing additional materials or components. Also, the garnish is mounted in a front door without reducing the surface area of the corresponding window of the vehicle.
