摘要

A ratchet-type ring spanner includes a handle (11) and a head portion (10) which, in turn, includes a circular peripheral wall (10a) defining a receiving compartment (12) and including a web area (10b) which connects with the handle (11), a cavity (13) being defined in the web area (10b). A ratchet wheel (20) is received in the compartment (12) and includes a plurality of teeth (21) in its outer periphery and a polygonal inner periphery. A pawl (14) is mounted in the cavity (13) and includes a plurality of teeth (142) defined on a first side for engaging with the teeth (21) of the ratchet wheel (20) and a second side bearing against a wall defining the cavity (13). A stop member (15) is mounted in the cavity (13) and includes a first end thereof bearing against the wall defining the cavity (13). A spring (16) is mounted between the stop member (15) and the toothed member to bias the toothed member away from the stop member (15).
