Removal of a pivotal element from its support is prevented when the pivotal element is subjected to a force in the direction of the pivot axis. A paper table 1 of a typewriter has a page end indicator 2 pivotally connected thereto through a mushroom 3, which comprises four separate portions, on the paper table 1 extending through an opening 4 in the page end indicator 2. This enables the page end indicator 2 to pivot about the center of the opening 4. When assembling the page end indicator 2 and the paper table 1, the mushroom 3 passes through the opening 4 in the page end indicator 2. A pin 5, which is supported on a bridge 6 mounted on the page end indicator 2, extends into the opening 4.
