A ratchet wrench (10) includes a driving end (12) including a ratchet member (20), two pawl mechanisms (30) releasably and selectively engaging with the ratchet member for setting the ratchet wrench in two operation modes, and a switching mechanism (40) disposed between the pawl mechanisms (30) and including limits urging the respective pawl mechanisms (30) such that one limit engages with one pawl mechanism to urge it to disengage from the ratchet member (20) while the other limit disengages from the other pawl mechanism (30) to allow it to engage with the ratchet member (20) in one operation mode, and the other limit engages with the other pawl to urge it to disengage from the ratchet member (20) while the one limit disengages from the one pawl to allow it to engage with the ratchet member (20) in another operation mode. Additionally, the pawl mechanisms are prevented from being mis-shifted by the switching mechanism.
