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.
