PROBLEM TO BE SOLVED: To provide a cap in which its inner surface is not rubbed even by repeating a moving operation for a long period, no crack or craze occurs even when the cap is erroneously dropped on a floor with a stable strength, a clip and a spring can be simply and accurately assembled when mounted at the cap, a reinforcing material is not moved on the inner surface of the cap, and a noise of moving due to rubbing of substances by moving a spring due to the movement of a clip is not generated. SOLUTION: The cap comprises a base of a clip inserted into a window hole provided at a side head of the cap molded by a mold for injection molding. The cap further comprises a spring, one end of which is engaged with a latch of the base disposed in the cap, and the other end of which is fixed in the cap. In this case, the clip is urged inward of the cap. The cap also comprises the reinforcing material disposed by simultaneously molded and fixed to the inner surface of the cap by insert molding to hold the other end of the spring. |
