description A ratchet wrench with a direction switching structure includes a wrench body with an axial slot, a control slot, and a pivot slot which are interconnected, and a ratchet wheel, a ratcheting member, and a switching member are installed therein, respectively. The switching member pushes against the ratcheting member through a prop member and selectively controls the engagement between the ratcheting member and the ratchet wheel. The circumferential wall of the pivot slot has a circular slot and a stepped surface formed at a position near an opening of the pivot slot provided for latching the switching member into the circular slot by a latch portion thereon and being stopped by the stepped surface for the positioning purpose. The prop member pushes against an appropriate position of the ratcheting member to prevent an unsecured engagement between the ratcheting member and the ratchet wheel.
