[0052] (Other embodiments)
[0053] (1) In the present invention, the surface 6A of the chafer 6 adjacent to the carcass ply 4 and above the chafer cord 6c may be provided with a second protrusion composed of a second topping rubber 6r. Strip protrusion 61. in Figure 4 A cross-sectional view of the carcass ply 4 and the chafer 6 of this embodiment is shown in FIG. In this embodiment, the carcass ply 4 and the chafer 6 are arranged such that the first ridge protrusion 41 and the second ridge protrusion 61 face each other. Thereby, since the distance between the carcass cord 4c and the chafer cord 6c can be appropriately maintained, deformation at the end of the component can be suppressed, and failures such as delamination can be prevented. However, since the gap between the carcass ply 4 and the chafer 6 becomes larger, there is a possibility of air entering.
[0054] (2) In addition, such as Figure 5 As shown, you can also Figure 4 The illustrated carcass ply 4 and chafer 6 ...
