<p>The invention relates to a screwing/unscrewing tool of the gun type, comprising: a body (30) extended by a handle (31) and housing a pneumatic motor (32) which can turn in order to rotate a terminal member about an axis (R); means (36) for selecting the direction of rotation of said motor (32) that can move between at least two positions each corresponding to one direction of rotation of said motor (32); and means (50) for reversing the direction of rotation of said motor (32). According to the invention, said reversing means (50) are integrated in a casing (502) so as to constitute an actuator which is independent of said selection means (36), and comprise shifting whereby said means (36) for selecting the direction of rotation can be shifted from one of said positions to the other, said shifting means being able to be actuated by successive translational movements having the same sense and direction.</p> |
