Abstract

A spring (2, 20) for a spring core (1, 10), wherein the spring has helical windings and a first end winding (201, 2001) and a second end winding (202, 2002), wherein at least the first end winding (201, 2001) has a free end (203, 2003) and the free end (203, 2003) has at least one passage (204, 2004) and the opening of the passage (204, 2004) is directed outwardly with respect to the end winding (201, 2001 or 202, 2002) of the spring (2, 20), is distinguished by the fact that the passage (204, 2004) is inclined out of a horizontal plane preferably about an angle alpha in the compression direction of the spring (2, 20).
