Ratchet wrench

A ratchet wrench comprising:

• a main body having a handle and a head section connected with a front end of the handle, the head section being formed with a receiving space axially passing through the head section, a cavity being formed at the front end of the handle and communicating with the receiving space of the head section;
• a ratchet wheel formed with ratchets and disposed in the receiving space of the main body;
• a restricting member connected with the head section for preventing the ratchet wheel from dropping out of the receiving space of the head section;
• two pawls disposed in the cavity, a post being connected with each pawl, the head section being formed with two slots respectively corresponding to the pawls, the posts of the pawls being slidably fitted through the slots, whereby the pawls can slide within the cavity along the slots, the pawls being formed with ratchets, a resilient member being compressed between the two pawls to abut against the two pawls;
• a shift member arranged on the head section of the main body for driving the pawls to slide and making one of the pawls engaged with the ratchet wheel;
• and
• a frictional plate tightly sandwiched between the shift member and the head section, the frictional plate having a boss protruding toward the head section, the shift member having a connecting section drivingly connected with the frictional plate.
