The utility model discloses a rubber module which comprises a bracket. The bracket is provided with a first oblique surface. The first oblique surface is provided with a rubber member which abuts against the first oblique surface. The bracket is provided with a fixing buckle for fixed mounting. The utility model further discloses a bill counter rubber module fixing structure which comprises the rubber module and a bill conveying rack. The bill conveying rack is provided with a second oblique surface which matches the first oblique surface. The second oblique surface is provided with a through hole which downwards penetrates through the bill conveying rack and matches the bracket. The side wall of the through hole is provided with a buckling part which buckles with the fixing buckle. The bill conveying rack is also provided with a bill conveying elastic sheet which closely presses the rubber member. According to the rubber module, through arranging the first oblique surface on the bracket, arranging the rubber member which abuts against the first oblique surface and arranging the fixing bracket for fixed mounting on the bracket, higher positioning accuracy of the rubber member is realized. By means of an inherent elastic force of the bill conveying elastic sheet, the bill conveying elastic sheet compresses the rubber member. Not only is labor saving realized in rubber member changing, but also simple and firm structure and convenient and safe assembling are realized.
