A castor means (1) which does not turn 180 DEG when being pulled forwards and backwards, but which otherwise has desired possibilities of movement and which may have a larger support area. A vertical mounting shank (3) may by the aid of load directions change sides and always cause the castor means to be in a dragged position, due to the fact that the vertical mounting shank is mounted in the core casing (2) of the castor means and may turn independently of the castor movement. The mounting shank (3) of the castor means projects through an opening (16) in the core casing (2) and is at its lower end movable on the inside of the core casing when the core casing is, during influence of a force caused to turn relative to the axis of rotation (10) of the castors (8, 9). |
