<p>Disclosed therein is a wrench with a retractable ratchet. The wrench includes a ratchet fixing hole formed from a side to an inner face of one of jaws of the wrench, wherein a sealing member is welded to the ratchet fixing hole in a state where a ratchet, an elastic member for retractably moving the ratchet, and the sealing member for supporting the elastic member are inserted into the ratchet fixing hole in order, or wherein a first sealing member is welded to the ratchet fixing hole in a state where a ratchet, an elastic member for retractably moving the ratchet, and the first sealing member for supporting the elastic member are inserted into the ratchet fixing hole in order, and a space of the ratchet fixing hole formed at a rear end of the first sealing member is filled and finished with a second sealing member. The wrench is prevented from being easily damaged due to a crack (formed on the slot of the jaw of the conventional wrench) and can be mass-produced since the ratchet fixing hole is formed integrally with the wrench by the casting work.</p> |
