PROBLEM TO BE SOLVED: To provide a falling moment measurement method in a vibration generator capable of measuring a relatively accurate falling moment. SOLUTION: This falling moment measurement method in a vibration generator is used for measuring the falling moment acting on the vibration generator 100 by a specimen 115 when the vibration is generated. The method includes respective steps comprising a step for installing one or more measurement means 113, etc., capable of calculating acceleration on the side faces of the specimen attached to a vibration base 105 and at positions flush with the gravity center of the specimen, a step for calculating acceleration in a direction perpendicular to the vibrating direction of the vibration generator based on the measurement result by the measurement means, and a step for finding the falling moment by the resonance of the specimen based on the calculated acceleration, the mass of the specimen and the height from the center of the vibration generator to the measurement means.
