PURPOSE: A device of a tire balance measurement unit for returning a sensor to a starting point is provided to reduce position errors of a 3-point supporting sensor and a measurement unit when seating the measurement unit on the sensor for measuring a tire balance value after transferring the measurement unit, thereby enhancing the reliability of measurement. CONSTITUTION: A device of a tire balance measurement unit for returning a sensor starting point accurately maintain seated states of a measurement unit(1) and 3-point supporting sensors(2a,2b,2c). Three ball casters(3a,3b,3c) are included in the lower part(1a) of the measurement unit. The ball casters are seated respectively on a cone-insertion groove(4), a V-shaped insertion groove(5), and a flat mounting surface(6) of the 3-point supporting sensors, thereby setting a sensor starting point of the measurement unit.
