Abstract
A ratchet wrench includes a head with a first room in which a ratchet wheel is rotatably received. A second room is defined in the inner periphery of the first room and a pawl is received in the second room. The pawl is biased by a resilient member in a recess defined in the inner periphery of the second room. A restriction member is located in the second room and has a first contact portion for contacting one end of the pawl, a second contact portion for contacting the engaging teeth of the pawl, and a contact corner for contacting the inside of the second recess. A gap between the first contact portion and the end of the pawl is 0 to 1 mm. The restriction member restricts the movement of the pawl in the second room.
