ABSTRACT:
An offset ratchet wrench is provided having a base seat disposed between upper and lower bars. The base seat is an elongated member, including two lateral faces which are not in contact with the upper and lower bars. A top face of the base seat contacts the upper bar and a bottom face of the base seat contacts the lower bar. At least one pair of locating projections are respectively disposed on the top and bottom faces of the base seat for preventing the base seat from longitudinal or transverse sliding between the upper and lower bars.
