A ratchet wrench includes a head rotatably receiving a drive member and slideably receiving two pawls each having a coupling portion. An elastic element is mounted between the pawls to bias the pawls to engage with a coupling section of the drive member. A ring is received in the head and pivotably mounted around an engaging portion of the drive member about a pivot axis. A reversing plate is pivotably mounted around a portion of the engaging portion of the drive member beyond the head about the pivot axis between first, second, and third operative positions. The reversing plate is connected to the ring to allow joint pivotal movement about the pivot axis. The ring includes a tail having two actuating portions respectively and releasably engaging with the coupling portions of the pawls responsive to movement of the reversing plate between the three operative positions.
