A ratchet wrench comprises a body, a ratchet, a first pawl, and a second pawl. Each of the first pawl and the second pawl can move between a first position and a second position relative to the ratchet. The first position is a position where the ratchet wrench can transmit torque to said driven element from respective first pawl or second pawl, and the second position is a position where no torque is transmitted from respective first pawl or second pawl. A control member can pivot or rotate to stay in one of a first position, a second position, and a neutral position for different operations. The body has an operating part comprising a groove. The groove comprises two accommodation chambers having inclined surfaces and can accommodate the first pawl and the second pawl.
