ている。The patch 8 is usually vulcanized by sandwiching a reinforcing cord layer 9 with a layer 10 of NR type rubber or SBR type rubber, and vulcanized. When used, the inner liner 7 and the patch 8 of the tire are used. The adhesive surfaces are pre-buffed, cement agents are applied to both sides, and then the applied patches are vulcanized and fixed at high temperature. It is known that when a butyl rubber is used for the rubber layer 10 of the patch, it does not substantially adhere to an inner liner of the same quality.

とする。However, when NR rubber is used for the rubber layer 10 of the patch, it is excellent in terms of fixing to the inner liner, but heat is applied to the entire surface exposed to filled air as the vehicle travels. Cracks occur due to oxidative deterioration,
As a result, it often leads to premature failure of the repair position.
Therefore, SBR rubber may be used, but the occurrence of cracks and the resulting failures are still problematic. The present invention has been made in view of the above problems, and an object thereof is to provide a repair patch having excellent durability.

することができるのである。The repair patch according to the present invention is a laminate including a first rubber layer and a second rubber layer which are exposed to the filled air and are to be fixed to the air chamber surface of the tire sandwiching the code layer between them. So, these first and second rubber layers are
The structural feature is that it is made of NR rubber and butyl rubber. As described above, the first rubber layer of the patch adhered to the air chamber surface of the tubeless tire, that is, the inner liner is made of NR rubber, so that the adhesion is strong, and the air does not come from outside the code layer. Made of transparent butyl rubber
(2) By covering with a rubber layer, the structure has a structure in which high-pressure filling air is shut off, so that it is possible to advantageously prevent the oxidative deterioration of the patch and the decrease in the adhesion force, which are promoted by the heat generated during running.
