Summary:PROBLEM TO BE SOLVED: To provide a sample attaching device of a vibration tester that makes the accuracy of a vibration test of handling only the Z-axis direction higher than that in the conventional art, by reducing the crosstalk acceleration occurring during the vibration test in the vibration tester.SOLUTION: A vibration tester 200 includes a vibration generator 11 for generating vibration, a vibratable vibration stand 12, a weight 13 as a sample, an L-shaped vibration tool 14, and a sample attaching device 15. The sample attaching device 15 includes an upper plate 16, a lower plate 17, an elastic member 18, a connecting rod 19, and a bearing part 20. Between the upper plate 16 and lower plate 17, the elastic member 18 energizes an elastic force in the direction in which the upper plate 16 separates from the lower plate 17. One end of the connecting rod 19 is oscillatably connected to the lower side of the upper plate 16 via the bearing part 20, and the other end is oscillatably connected to the upper side of the lower plate 17 via the bearing part 20.SELECTED DRAWING: Figure 2 【課題】振動試験装置において振動試験時に発生するクロストーク加速度を低減し、従来よりもZ軸方向のみを対象とした振動試験の精度に優れた振動試験装置の供試体取付装置を得る。【解決手段】振動試験装置200は、振動を発生させる振動発生機11、振動可能な振動台12、供試体であるウエイト13及びL型加振治具14、並びに、供試体取付装置15を有している。供試体取付装置15は、上部プレート16、下部プレート17、弾性部材18、コンロッド19、軸受部20を有している。弾性部材18は、上部プレート16と下部プレート17との間において、上部プレート16と下部プレート17とが離れるような方向に弾性力を付勢している。コンロッド19は、一端が上部プレート16の下部側に軸受部20を介して揺動可能に接続されているとともに、他端が下部プレート17の上部側に軸受部20を介して揺動可能に接続されている。【選択図】図2
