The vibration to occur in elevator traction machine may cause the vibration noise in the living room in the neighborhood. In this paper, We tried vibration properties analysis of the trestle of traction machine using the operational mode analysis for the purpose of the transmission reduction to the building of vibration. We confirmed that the mode analysis of the trestle of traction machine under the actual machine operation was possible. In addition, we confirmed the improvement of the vibration transmission characteristic to the building by the structure change plan by an experiment and confirmed the effectiveness of this technique.
