Abstract
An amusement ride device comprises a track composed of a pair of parallel rails and having a central axis extending between the rails, and a car adapted to travel along the track. The car includes a car body, a pair of front wheels and a pair of rear wheels adapted to be rotated in contact with the rails, thereby allowing the car body to travel along the rails, a swinging frame, having the rear wheels rotatably supported on each end thereof and extending substantially at right angles to the advancing direction of the car, and a bogie shaft attached to the car body so as to extend in the advancing direction of the car and pivotally supporting the swinging frame. The track includes a first straight section, a twist section continuous with the first straight section, at which the rails are twisted together at a predetermined angle to the central axis, a second straight section continuous with the twist section and having an overall length at least equal to that of the car, and an arcuate curve section continuous with the seocnd straight section, the respective central axes of the first and second straight sections and the twist section being substantially in line with one another.
