To provide a ratchet wrench by which the rotational direction of a socket can be switched with only a hand of one side while used to grip a handle. In a ratchet wrench, rotation of an output shaft of an air motor is transmitted to a ratchet unit via a reduction gear unit in order to rotate a spindle connected to the ratchet unit, and the ratchet unit is accommodated within a ratchet housing. The ratchet wrench includes a cover plate which covers one face of the ratchet housing opposite the other face thereof from which the spindle projects. A pair of reverse buttons are disposed on the cover plate to be slidable along a direction parallel to an output shaft of the air motor. A pair of reverse arms rotatably are attached to the reverse buttons, each reverse arm being movable together with the corresponding reverse button. The ratchet wrench further includes a reverse gear which the reverse arms engage upon movement of the reverse arms caused by sliding movement of the reverse buttons. The reverse gear is rotated in one direction when one of the reverse arms engages the reverse gear and rotated in the opposite direction when the other reverse arm engages the reverse gear. |
