In addition, noise was increased and the work environment was deteriorated. On the other hand, the one using a motor as a power source,
Although the above-mentioned problems of easy operability and noise deterioration have been solved, there is a drawback that effective vibration cannot be obtained.

Therefore, the present invention has been made for the purpose of solving these problems, and by using a motor as a drive source, it is possible to secure effective vibration while achieving a simple operation and noise reduction. Provided is a surface leveling device for a fluid material.
