Abstract: When a pillar bracket is formed, as a protruding portion is integrally formed outward from an edge of a headliner, and a weather strip is fitted onto the protruding portion, the weather strip may maintain a predetermined shape to prevent a gap from being generated between the headliner and the weather strip. In this case, as the protruding portion is formed to always remain in close contact with a vehicle body panel, since the protruding portion fixedly supports the weather strip in close contact with the vehicle body panel and is not pushed any further, the weather strip may not be pushed or bent any further and may always maintain a predetermined shape. In addition, as a protruding rib integrally protrudes from the protruding portion, the protruding portion may fixedly support the weather strip more firmly in close contact with the vehicle body panel and thus more firmly and fixedly support the weather strip.
