Abstract
An amusement track ride system comprises a pair of rails forming a track including a spinning section. A car traveling along the rails includes a chassis, a passenger seat on the chassis, and a plurality of wheel portions situated close to the feet of a passenger in a passenger seat. In the spinning section, the rails extend in a helix along an inner surface of an imaginary cylinder having a central axis, the diameter of the imaginary cylinder being set so that the axis of helical rotation of the car traveling in a spin along the rails passes through the car and is substantially in alignment with the central axis of the imaginary cylinder. The holding device has a shoulder retainer provided at the back rest for holding down the shoulders of the passenger in the passenger seat from above. The retainer is guided by a guide mechanism to be movable in the extending direction of the seat back rest, and locked by a locking mechanism in a position where the retainer abuts against the passenger's shoulders.
