The utility model relates to a lever inner diameter meter able to eliminate gaps. An inner diameter meter is applied to measure tolerance of an inner dimension and the shape, which is achieved in the way that a movable probe is provided at one end of the main body of the inner diameter meter frame; when the movable probe moves, the lever is driven to revolve and the probe of the indicator is driven by the mandrel so that the needle of the indicator revolves. But this structure can not remove invalid stroke between the movable probe and the lever, which makes the needle not able to restore and provides a poor indicating stability. The lever inner diameter meter able to eliminate gaps in the utility model comprises a main body (2), a movable probe (1), a lever (3), a mandrel (4) and a tapered spring (5); wherein the movable probe is provided at one end of the main body (2), the tapered spring is provided on the movable probe (1); moving of the movable probe (1) enables the lever (3) to revolve; the movable probe (1) contacts with the lever (3) all along. The utility model is applied to measure tolerance of an inner dimension and a shape.
