PURPOSE:To reduce the rotational torque of an integrating meter by pressing a spacer toward a digit wheel with a spring and securing a gap equivalent to a proper thrust between the digit wheel and the spacer by means of a stage part formed to a shaft supporting the digit wheel. CONSTITUTION:The integrating is carried out by 1/10 revolution of an upper digit adjacent to a lower digit to a revolution of a digit wheel 16 from a driving shaft via a transmission shaft 8, a gear shaft 12 and the 1st gear 13. Then a spacer 20 is pressed by a spring 21, and the barrel part 20b of the spacer 20 abutes a stage part 14a of a shaft 14. As a result, a proper gap A is formed between a flange 20a of the spacer 20 and the most significant digit of the wheel 16. This prevents the application of the force of the spring 21 to each wheel 16 and therefore avoids the application of excessive load to each wheel 16. Thus the smooth integrating drive is possible. |
