    • PROBLEM TO BE SOLVED: To prevent the deviation of a vehicle by forming a slope or a curved surface on the inside face of a curbstone for a carriage way, to reduce frictional resistance, and guiding a steered wheel in the carriage way without breaking a rim or a tire when it is brought into contact with the curbstone. SOLUTION: A guide face (flat face or a curved face) at the inclination of 80 deg. or below against a road surface 2 is provided on the inside face of a rail (curbstone) for a carriage way provided at a garage, a superhighway tollgate, a drive through or the like. A stainless sheet or the like is provided on the guide face to make the surface smooth and to reduce frictional resistance. When the tire 3 of a steered wheel is brought into contact with the lower section of a rail (curbstone) and tends to ride on it, the tire 3 is slid, the balance of moment around the axes of the right and left kingpins is broken, the steered wheel is oscillated, and a vehicle is guided in the vehicle passage, thereby the deviation of the vehicle to the outside of the vehicle passage is prevented, and safety can be secured.
