Claims

[Scope of utility model registration request]

A plurality of number rings are rotatably provided on the support shaft, continuous teeth are formed on the lower digit side of the number ring, and one intermittent tooth is formed on the front side of the upper digit side of any number ring in the digit rotation direction. At the same time, at least one intermittent valley tooth is formed on the rear side of the intermittent mountain tooth in the direction of shift rotation, so that the continuous tooth can be simultaneously engaged with the adjacent intermittent mountain tooth and intermittent valley tooth, thereby increasing the tooth width. A pinion is provided which has long long teeth and short teeth with short tooth widths alternately, and a locking surface that can be opposed to one side of the short teeth on the upper digit side of the number ring and a locking surface that can be opposed to one side of the short teeth and the top surface of the two adjacent long teeth are provided at the same time. A reverse rotation prevention device for a totalizer, characterized in that the totalizer is provided with an opposing locking peripheral surface other than the intermittent valley teeth to prevent reverse rotation, and is configured with a spring member capable of regulating the free movement of the pinion. .
