PROBLEM TO BE SOLVED: To make it possible to increase a vehicle traction speed while suppressing a drop-weight falling height.SOLUTION: A collision testing device 1 comprises a drop-weight 23, a suspension part 21b, a traction rope 80 and a moving pulley device 50. The traction rope 80 transmits a falling motion of the drop-weight 23 relative to the suspension part 21b to a vehicle 11 and tows the vehicle 11 in the horizontal direction. The moving pulley device 50 comprises a fixed pulley 61 and moving pulleys (71, 73). A rotary shaft of the fixed pulley 61 is fixed to the suspension part 21b and the traction rope 80 is put on the fixed pulley 61. Rotary shafts of the moving pulleys 71, 73 are fixed to the drop-weight 23 and the traction rope 80 is put on the moving pulleys 71, 73.SELECTED DRAWING: Figure 1 【課題】落錘の落下高さを抑制しつつ、車両の牽引速度を速くできるようにする。【解決手段】衝突試験装置１は、落錘２３と、吊下部２１ｂと、牽引ロープ８０と、動滑車装置５０と、を備える。牽引ロープ８０は、吊下部２１ｂに対する落錘２３の落下運動を車両１１に伝達し、車両１１を水平方向に牽引する。動滑車装置５０は、定滑車６１と、動滑車（７１・７３）と、を備える。定滑車６１は、吊下部２１ｂに回転軸が固定され、牽引ロープ８０が掛けられる。動滑車（７１・７３）は、落錘２３に回転軸が固定され、牽引ロープ８０が掛けられる。【選択図】図１
