PROBLEM TO BE SOLVED: To restrain vibration of a component along a direction in parallel to a rotary shaft of a measured object to conduct unbalance measurement of a reduced error, as to a support device used for the unbalance measurement of a rotor requiring balance of rotation such as a rotation-measured object of a motor, a fan and a rotary shaft. SOLUTION: This unbalance vibration detection mechanism is provided with a bearing for supporting the shaft of the measured object rotated at a high speed, a bearing member provided with the bearing, a support means for supporting the bearing member to be vibrated freely within a horizontal plane, and a vibration sensor provided in a base. In the unbalance vibration detection mechanism, the vibration generated from the measured object rotated at the high speed is detected by the vibration sensor, and a vibration direction regulating means is provided to regulate at least the vibration in parallel to the rotary shaft of the bearing member.
