The object of the invention is a base structure for fixing a vertical post of a traffic sign, of a lamp or corresponding to a platform structure, such as to a lattice-type platform or to a concrete platform. The base structure comprises at least a fixing part to be position-wise adjustably fixed to the platform structure by the aid of a spherical adjustment part. The spherical adjustment part is at the bottom end of the fixing part, and the base structure comprises a locking means provided with a hole, which locking means when locking the fixing part into its position is placed by its hole on top of the spherical adjustment part of the fixing part. |
