The ratchet wrench has a body, a drive ring, two pawls, two resilient arms, a retaining ring and a split ring. The body has a handle and a box end with a ratchet hole and multiple ratchet teeth formed around and protruding into the ratchet hole. The drive ring and pawls are mounted rotatably in the ratchet hole, and the resilient arms connect the pawls to the drive ring and press the pawls against the ratchet teeth. The retaining ring is mounted around the drive ring and holds the retaining ring in the ratchet hole. The split ring connects the retaining ring to the drive ring.
