The operation of the caster 1 according to this embodiment will be described with reference to FIG. 1. On a flat floor surface, an arrow X
When the direction is suddenly changed diagonally forward or laterally, the caster 1 is pulled by the contact pressure with the floor surface and cannot follow the movement of the cleaner body 2, and the cleaner body is in the position indicated by the imaginary line A. It is rotationally displaced relative to 2. Therefore, the virtual triangle T that connects the contact points between the rear wheels 10 and the floor surface of the small wheel 12 is transformed from the isosceles triangle shape to the isosceles triangle shape, and the rotation direction X thereof with respect to the cleaner body 2 is changed. A tensile force acts in a direction in which the front end corner portion B of the vehicle tilts downward, but at this time, since the caster 1 is arranged at the intake port 7, the distance between the small wheel 12 and the rear wheel 10 is long, and stability is improved. Further, the virtual triangle T connecting the contact points between the rear wheels 10 and the floor surface of the small wheel 12 is deformed from the isosceles triangular shape to the isosceles triangular shape, and the angle C is reduced, so that the caster 1 performs the original function. It is like this.
