摘要： The present invention provides a tire balance measuring device capable of minimizing the influence exerted on a measured value due to an inclination of a lock shaft even when the lock shaft (fitted shaft) is inclined in a random direction at an angle created by a gap corresponding to a fitting allowance every time a tire is supplied with gas. The tire balance measuring device of this invention comprises a sensor for measuring the inclination of the lock shaft, and a computing unit for computing an amount of change in a unbalance of the tire from an output value received from the sensor after the tire is supplied with gas, and correcting a result of measuring a balance of the tire using the computed amount of change in the unbalance.
