Claim 13:
14. A tappet configured for acting on a pump piston of a high-pressure fuel pump of an internal combustion engine, the tappet comprising:
a tubular housing having first and second indented surfaces arranged diametrically opposite each other at a first end of the tubular housing, the first and second indented surfaces configured to receive a first pin supporting a cam follower roller;
a transverse beam having:
an upper end face configured to engage: i) a first axial inner end face of the first indented surface, and ii) a second axial inner end face of the second indented surface; and
a lower end face configured to engage a second pin, the second pin protruding beyond a lower annular end face of the tubular housing;

a spring plate disposed within the tubular housing, the spring plate having a wedged piece comprising:
a sleeve-like inner collar configured to guide the second pin, the sleeve-like inner collar having an annular end face; and
from the annular end face, the spring plate extends radially outward and upward toward the lower end face of the transverse beam such that an annular tip is formed, the annular tip configured to rest against the lower end of the transverse beam; and
from the annular tip, the spring plate extends radially outward and downward toward the lower annular end face of the tubular housing such that an annular collar is formed, the annular collar pointing downward and configured to attach the spring plate to an inner casing of the tubular housing.
