摘要： A ratchet wrench includes a body, a ratchet wheel, a pawl, a switch member and a resilient member. The body has three recesses to respectively accommodate the ratchet wheel, the pawl and the switch member. The pawl has a driving portion to be engaged with the toothed portion of the ratchet wheel. The pawl has a second engaging portion which is engaged with a first engaging portion of the ratchet wheel to position the ratchet wheel and the pawl in the two respective recesses respectively. The pawl has a protrusion which has a curved recess and a first stop. The switch member has a second stop, a reception recess and a hole. The protrusion is accommodated in the reception recess. The resilient member extends through the hole and the two ends of the resilient member contact the reception recess and the curved recess respectively.
