IPC: F16L11/08
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To improve the durability while maintaining the expansion, shrinkage, and reinforcing performances of a bias cord layer by providing a cushion rubber layer having a specific thickness between cord layers. SOLUTION: A plurality of cord layers 3 in which long fiber materials are spirally arranged in parallel are provided between an inner face rubber layer 1 and an outer face rubber layer 2, a bias cord layer 4 in which the cord layers 3 which are adjacent mutually are arranged in such a way that their spiral winding directions differ from each other is provided, and a cushion rubber layer 5 having a thickness of 2 mm or more and 10 mm or less is provided between the cord layers 3. This cushion rubber layer can absorb the energy generated due to the displacement of a reinforcing cord to suppress the generation of load in the cord layer 3 and improve the durability of the cord layer. At this time, if the cushion rubber layer 5 is too thin, it cannot absorb the energy sufficiently.  Moreover, if it is too thick, each cord layer acts independently across the cushion rubber layer 5, and the synergistic reinforcing effect cannot be exhibited.
