An integrating meter comprising a rotatable masking ring integrally containing elastic members for applying a predetermined thrust pressure to a plurality of less to more significant digit number rings rotatably aligned on a support shaft, the masking ring being positioned to the left of the most significant digit number ring. This construction eliminates the need for a conventional coil spring for pushing the number rings in the thrust direction. With the number of its parts reduced, the integrating meter is easy and inexpensive to manufacture.
