  • Patent number: 8740276
    Abstract: A molding end cap includes an end section and an insertion section that is inserted into a molding main body. The molding main body includes an outer surface section and a bent section. One of the insertion section and the bent section includes an engagement protrusion and the other thereof includes an insertion slope section and a hooking section. The engagement protrusion undergoes elastic deformation by the insertion slope section in a deformation direction that intersects an insertion direction. The hooking section holds the engagement protrusion in a state in which the engagement protrusion is restored from elastic deformation. The engagement protrusion formed in a shape of a rib ensures that the engagement protrusion is deformed to only a small extent in the insertion direction but easily undergoes elastic deformation in the deformation direction.
