The invention refers to a castor wheel with a rotatably supporte forked journal (3, 4). The castor wheel can be attached to a base thereby that an attachment member (8), which is rotatable relative to the forked journal, is provided with a threaded portion (11) intended to cooperate with a correspondingly threaded portion of the base, and thereby that the outer contour of the attachment member has a shape suited for exerting it to a torque. The contour is preferably in the form of a nut. |
