Abstract: A ratchet wrench is designed to prevent overshooting and unintended switching of drive direction. The ratchet wrench has a wing member 44, which is biased by a spring 58 through a bushing pin 56, wherein an elastic member 66 formed of an elastic material, such as rubber, is incorporated into an axial internal space of the spring 58. Thereby, it is possible to strengthen a pressing force in a direction of holding engagement between a pawl of the wing member 44 and an internal gear 30 of an oscillating member 26. Thereby, in the case where a force is exerted on the wing member 44, in a direction tending to release the engagement between the pawl 46 of the wing member 44 and the internal gear 30 of the oscillating member 26, the spring 58 and of the elastic member 66 exert a reaction force, and the elastic member 66 functions as a stopper to prevent overshooting.
