PURPOSE: A sun shade pulling tube cap is provided to strongly combine a pulling tube and a pulling tube cap by supporting the end of a pulling tube at both inside and outside by installing a guide rail within a pulling tube. CONSTITUTION: A sun shade pulling tube cap is composed of a tube opening(1), a roller opening(3), a roller(5), and a roller pin(7). The tube opening is inserted while covering the end part of a pulling tube. A guide rail(11) is formed in the center of the tube opening. The guide rail guides the linear route of the roller pin to an inner wall of the tube opening. The roller opening is opened to the direction perpendicular to the opening direction of the tube opening. The roller is inserted in the roller opening. The roller is rotated around a rotation shaft parallel to the opening direction of the tube opening. The roller pin passes through the center of the roller. The roller pin is used as a rotation shaft of the roller.
