摘要

A tire balance measuring apparatus (1) comprises a rotary drive section (17), an eccentric force measuring unit (16), a calculation unit (22), and an evaluation unit (23). The eccentric force measuring unit (16) measures an eccentric force (F) generated in a main shaft (12). The calculating unit calculates an eccentricity amount of the main shaft based on the eccentric force measured by the eccentric force measuring unit. The evaluation unit (23) evaluates the eccentricity amount of the main shaft (12) based on a correlation between the eccentric force (F) measured by the eccentric force measuring unit (16) when the main shaft (12) is rotated at a predetermined rotational speed is, and the rotational speed.
