Zusammenfassung:	A ratchet mechanism of a ratchet wrench having a pawl carrier and first and second pawls. The pawl carrier includes a groove and is rotatable to cause selection of one of first and second drive directions. The first and second pawls are adapted to selectively engage with a toothed portion of a ratchet gear for selecting one of the first and second drive directions. Each of the first and second pawls includes a projection adapted to engage the groove when the pawl carrier is rotated to cause one of the first and second pawls to disengage from the toothed portion and the other of the first and second pawls to engage the toothed portion.
