Power transmission belt and method for fabricating the same
A power transmission belt includes a transparent or semitransparent sheet material covering a portion of a surface of a belt body including a mark. At least a portion of the belt body covered with the sheet material is made of a rubber composition vulcanized with sulfur. The sheet material is made of a rubber material containing a diene rubber. The sheet material is vulcanized with sulfur together with the rubber composition forming the portion of the belt body covered with the sheet material such that the sheet material is connected to the belt body.
