<p>PURPOSE:To provide a vibration measuring device capable of inspecting the noises or the like caused by the mechanical defect of the bearing of a small motor with high precision. CONSTITUTION:A pressing piece 4 is put on the nonrotation section of a motor 2 on a motor holding base 1, and the pressing piece 4 is pressed to the motor 2 side by a pressing means 5 to apply the preset pressure to the nonrotation section. A detector 6 is provided on the pressing piece 4, and the motor vibration acceleration is detected by the detector 6. Whether the detected acceleration is the preset level or below is judged by a judging means 7.</p> |
