Abstract
Abstract A toy building set element is formed of a first part and a second part which is slidable and resiliently journaled with respect to the first part. Both of the parts have coupling elements thereon which permit coupling of the parts to other elements of the toy building set. One of the parts may be adapted to receive a shaft through a cylindrical opening that runs perpendicular to the displacement direction of the parts with respect to each other.
