DEFINITION

Classification: 411/124

Projection on member and coacting formation in substructure:

(under subclass 123) Device wherein the means on the member is in the form of one or more teeth, ridges or the like, which form axial extensions of the member, and wherein the substructure has one or more recesses, grooves or the like for either receiving the teeth, etc., or otherwise cooperating with them to restrict rotation of the member relative to the substructure.
