Abstract
A ratchet wrench includes a head with a ratchet wheel received in the first room in the head. A second room is defined in the inner periphery of the first room. The head has a top closed portion and a bottom closed portion, the second room is located between the top and bottom closed portions. A pawl is located in the second room and a resilient member is biased between the pawl and the inside of the second room so as to engage the pawl with the ratchet wheel. A positioning hole is defined through the top and bottom closed portions. A pin extends through the positioning hole and has a section located in the second room to restrict the movement of the pawl in the second room. The pawl can be made smaller than the pawls used in the conventional ratchet wrenches.
