The present invention relates to a tab setting device for stopping a carriage of a typewriter at a desired position. This tab setting device includes an unusual-shape hole formed in a frame of the typewriter in which a tab bracket can rock. In this unusual-shape hole, two pairs of projections for supporting the tab bracket are formed on the bottom surface, one pair of the projections serve as fulcrums for rocking of the tab bracket when a tab pin or pins are tab-set, while the other pair of the projections serve as fulcrums for rocking of the tab bracket when a tab pin or pins are cleared.
