Abstract
Abstract The stop member has a shape of revolution and an L-shaped cross section. The re-entrant angle defined by the two branches of the L faces the axis of the member. A skirt portion of the member which corresponds to the branch of the L which is parallel to the axis of the member has corrugations. A flange of the member which is perpendicular to the axis of the member corresponds to the other branch of the L. The stop member can be combined with an annular groove of a shaft to axially retain the shaft. The diameter of the opening defined by the flange of the member is slightly larger than the diameter of the shaft and the minimum diameter defined by the corrugated skirt portion is less than the diameter of the shaft. A method and device for producing the stop member are also described.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
98 words
A stop member, in particular for axially retaining at least one element located at the periphery of a central element, said member having a general shape of revolution and a substantially L-shaped cross section, a re-entrant angle defined by the two branches of the L facing the axis of the member, a skirt portion of said member which corresponds to a branch of the L which is substantially parallel to said axis having corrugations, and a flange of said member which is substantially perpendicular to the axis of said member corresponding to the other branch of the L.
Claim 2
Dependent Claim
98 words
A stop member, in particular for axially retaining at least one element located at the periphery of a central element, said member having a general shape of revolution and a substantially L-shaped cross section, a re-entrant angle defined by the two branches of the L facing the axis of the member, a skirt portion of said member which corresponds to a branch of the L which is substantially parallel to said axis having corrugations, and a flange of said member which is substantially perpendicular to the axis of said member corresponding to the other branch of the L.
Claim 3
Dependent Claim
35 words
A stop member as claimed in claim 1, wherein the corrugations have inner crests which define an opening whose diameter is less than the diameter of an opening defined by the flange of the member.
Claim 4
Dependent Claim
21 words
A stop member as claimed in claim 1, wherein the skirt portion has corrugations which are outwardly inclined in some zones.
Claim 5
Dependent Claim
157 words
An axial stop device for acting as a stop for at least one element on a central element, comprising a retaining groove in the central element and a stop member elastically engaged in the groove, the stop member having a general shape of revolution and a substantially L-shaped cross section, a re-entrant angle defined by the two branches of the L facing the axis of the member, a skirt portion of said member which corresponds to a branch of the L which is substantially parallel to said axis having corrugations, and a flange of said member which is substantially perpendicular to the axis of said member corresponding to the other branch of the L, the diameter of the opening defined by the flange of said member being slightly greater than the diameter of the central element and the minimum diameter of the opening defined by the skirt portion being less than the diameter of the central element.
Claim 6
Dependent Claim
157 words
An axial stop device for acting as a stop for at least one element on a central element, comprising a retaining groove in the central element and a stop member elastically engaged in the groove, the stop member having a general shape of revolution and a substantially L-shaped cross section, a re-entrant angle defined by the two branches of the L facing the axis of the member, a skirt portion of said member which corresponds to a branch of the L which is substantially parallel to said axis having corrugations, and a flange of said member which is substantially perpendicular to the axis of said member corresponding to the other branch of the L, the diameter of the opening defined by the flange of said member being slightly greater than the diameter of the central element and the minimum diameter of the opening defined by the skirt portion being less than the diameter of the central element.
Claim 7
Dependent Claim
43 words
A device as claimed in claim 4, comprising an apertured element to be retained, the maximum diameter of said member in the region of the skirt portion being slightly greater than the inside diameter of the aperture of the element to be retained.
