Abstract: [Object] In a vehicle-collision simulation testing apparatus, to make it possible to downsize the apparatus with lightweight. [Solution] A sled 11 is supported in a movable manner in a back-and-forth direction, a yawing sled 14 is arranged on the sled 11 in a horizontally rotatable manner with a front portion supported by a rotation shaft, on which a product under test can be mounted, an eccentric mass 17 is arranged on a side of a rotation shaft on the yawing sled 14, and a launching device 18 that applies a backward acceleration on a front side of the sled 11.
