PROBLEM TO BE SOLVED: To display numerical figures large, and make printing the figures easy on the out side of the digit wheel, while making width of a consumed gas integration counter of a gas meter compact. SOLUTION: The integration counter of the gas meter is constitute that the plurality of digit wheels 2 with 0 to 9 figures are aligned rotatably around the shaft 1, while interleaving the supporting plate 4 in-between the adjacent digit wheels, supporting the carry gear 3 on the support shaft 14 of the supporting plate rotatably and both the sides of the carry gear 3 are engaged with the adjacent digit wheels, the intermittent gear 17 which engages once when the lower significant digit wheel turns one revolution is provided one side of the carry gear, and a pinion 16 engaging with the one side of the higher significant digit wheel. The construction of the digit wheel is that from the outer periphery of the disk 6 provided with a shaft to be passed through, extending the outer ring 7 for numerical figure to both the sides, from the inner side of the digit wheel the ring 8 for engaging is extended to both the sides, the inner gear 9 for engaging with the pinion is provided in one side of the inner ring, and the recessed part 10 for intermittently engaging with the intermittent gear is provided on the other side of the inner ring.
