To provide a simplified yawing device of an automobile collision simulation test device capable of reproducing yawing operation, and reducing a device cost and a necessary space.

This simplified yawing device of the automobile collision simulation test device has a sled for loading a specimen thereon, a guide rail for supporting the sled slidably forward and backward, and a body device equipped with an actuator for discharging the sled from the state in contact with the front end of the sled. Two rails for pitch are provided along the guide rail, and a rail for pitch and yaw is provided on the outside thereof. The sled supports a longitudinal frame vertically rotatably, and connects a middle sled to the longitudinal frame vertically rotatably, vertically slidably, horizontally unrotatably and horizontally unmovably. The middle sled is loaded with the specimen in the offset state, and the front and rear parts thereof are shoe-supported by the rail for pitch and the rail for pitch and yaw. The rail for pitch and yaw in a section where the shoe is slid is formed by changing the lateral direction displacement distance.
