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