A ratchet wrench includes a head. The head delimits a receiving space and a recess. The recess connects with the receiving space. The recess delimits an opening adjacent to the receiving space. A gear wheel is disposed in the receiving space and includes an outer circumference defining a first engaging area. A pawl mechanism is restrained in the recess and includes a surface defining a second engaging area facing and in ratcheting engagement with the first engaging area. A groove is defined on the outer circumference of the gear wheel. The pawl mechanism engages with the groove and restrains the gear wheel in the receiving space.
