PURPOSE:To simplify mounting and demounting of a tire wheel, by a method wherein a fixed point for mounting and demounting of the tire wheel is positioned on a parallel line to the center line of an axle. CONSTITUTION:A tire wheel support plate 2 is formed in the shape to which the diameter of a wheel support plate is increased, and the forward end thereof is formed into a cylindrical type to form a tire wheel engaging part. Tire guiding piece 4 are disposed in several spots on a circumference, and serve to facilitate matching of the position of a rod 5 with the position of a hole in the tire wheel when the tire wheel is forcibly pressed in. After mounting of the wheel, the rod 5 is positioned outside the width of the wheel support plate 2, and this prevents the occurrence of power strain in a way that rotation of a wheel exerted on the rod 5 and a force in a reverse direction are exerted on the plate togetherwith the rod 5. This permits facilitation of mounting and demounting of the tire wheel. |
