Molding end cap

A molding end cap that is fitted into an end of a molding main body, the molding end cap comprising:

• an end section that closes an open end of the molding main body;
• and
• an insertion section that protrudes from the end section, and is inserted into an opening of the molding main body,
• the molding main body including an outer surface section, and a bent section that is bent inward from the outer surface section on an inner side of the molding main body,
• one of the insertion section of the end cap and the bent section of the molding main body including an engagement protrusion, and the other of the insertion section of the end cap and the bent section of the molding main body including an insertion slope section and a hooking section, the engagement protrusion coming in sliding contact with the insertion slope section, and undergoing elastic deformation in a deformation direction that perpendicularly intersects an insertion direction when the insertion section of the end cap is inserted into the opening of the molding main body, and the hooking section being formed by forming a cut on a back side relative to the insertion slope section, and holding the engagement protrusion in a state in which the engagement protrusion is restored from elastic deformation, and
• the engagement protrusion being formed in a shape of a rib that 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.
