A ratchet device for a screwdriver comprising:

• a body adapted to be partially secured in a handle of the screwdriver and including:
• a first through hole longitudinally and centrally defined in the body, the first hole being a sunken hole;
• a column adapted to be securely received in the handle of the screwdriver;
• a pivot seat integrally and radially extending from the body out of the handle of the screwdriver, wherein the first through hole has a first section defined in the column and a second section defined in the pivot seat, the first section of the first through hole having a diameter smaller than that of the second section of the first through hole in the pivot seat;
• a channel defined in the pivot seat, the channel corresponding to and communicating with the second section of the first through hole in the body;
• and
• a recess defined in a top of the pivot seat, the recess communicating with the first through hole and the channel in the body;
• a barrel partially and pivotally received in the first through hole in the body, the barrel having a series of teeth formed on an outer periphery of the barrel and a polygonal hole longitudinally and centrally defined in the barrel, the polygonal hole extending through the barrel;
• and
• a controller pivotally mounted on the pivot seat and including:
• a first pawl and a second pawl each received in the channel and corresponding to each other, the first pawl and the second pawl selectively engaged to the series of the teeth on the barrel to control an operated direction of the barrel;
• a spring received in and mounted between the first pawl and the second pawl, the spring having two opposite ends each abutting a corresponding one of the first pawl and the second pawl;
• a cover pivotally mounted around the pivot seat for driving the first pawl and the second pawl to selectively engage to the series of teeth on the barrel;
• and
• a guiding plate fixedly received in the recess in the pivot seat and having a second through hole defined to align with the first through hole in the body, the guiding plate having a first guiding groove and a second guiding groove defined therein, the first guiding groove and the second guiding groove each having a first portion diametrically corresponding to each other relative to the second through hole and concentrically located relative to the second through hole, the first guiding groove and the second guiding groove each having a second portion extending from the first portion and directing to a periphery of the guiding plate.
