A ratchet wrench includes a wrench body, a ratchet wheel, a pawl member, and an elastic member. Thus, when the ratchet wrench jams during operation, the jamming prevention portion may force the pawl member to detach from the ratchet wheel, thereby preventing the ratchet wrench from jamming during operation. In addition, when the pawl member compresses the elastic member to a determined extent, the jamming prevention portion applies a reaction on the wall of the locking recess of the wrench body, so that the pawl member will not compress the elastic member to an excessive extent, thereby preventing from wearing the elastic member.
