ABSTRACT:
A hub driving assembly is adapted to uni-directionally transmit a driving force of a sprocket to rotate a hub, and includes a sprocket-mounting cylinder having retreat bores which respectively extend from a tubular end surface through an outer cylindrical surface, and positioning holes which extend axially from the tubular end surface. A plurality of pawls are disposed in the retreat bores, and are biased by biasing members in the retreat bores to be movable between a driving position, where the pawls extend radially and outwardly for engaging the hub, and an idle position, where the pawls retreat into the retreat bores. A barrier member includes a ring abutment and a plurality of inserts fitted into the positioning holes to bring the ring abutment into abutment against the tubular end surface so as to prevent removal of the pawls and the biasing members from the bores.
