Title: Oneway ratchet wrench

Abstract: A oneway ratchet wrench includes a wrench body, a ratchet wheel, and a drive mechanism. The drive mechanism includes a support plate, a oneway pawl member, and an elastic member. Thus, the elastic member is mounted between the support plate and the oneway pawl member, so that the wall of the receiving recess of the drive head needs not to additionally provide a blind hole for mounting the elastic member, thereby facilitating assembly of the oneway ratchet wrench, and thereby decreasing costs of fabrication.
