The head tube extends integrally from a front end of the upper tube and a front end of the lower tube. The head tube has a chamber communicates with a chamber of the upper tube and a chamber of the lower tube. Two inner tubes are provided in the chamber of the upper tube. The abutted portions of the two inner tubes form a rib such that the structure strength of the upper tube is improved.
