  • Snap-ring-connected coaxial annular members
    Patent number: 4013373
    Abstract: Two annular members, such as a sleeve and an abutment ring, are held together by a snap ring of generally V-shaped (or Y-shaped) cross-sectional profile with a pair of lips with a mirror-symmetrical confronting annular grooves of the members, the arms of the V (or Y) resting against tapering rims of the grooves. The rims and the arms terminate in beveled edges serving, upon the fitting of one lip of the connecting ring into the groove of one member, to cam the other lip radially inwardly for letting it snap into the groove of the other member as the two members are axially pressed together.
