Claim 0:
1. 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 two surfaces arranged diametrically opposite each other at an upper annular end face of the tubular housing, the two surfaces: i) indented relative to an outer casing of the tubular housing, and ii) comprising a first pin supporting a cam follower roller;
a transverse beam having:
an upper end face configured to lie against axial inner end faces of the two surfaces; and
a lower end face facing a lower annular end face of the tubular housing is provided with a non-stepped second pin protruding from the tubular housing; and

a spring plate attached to an inner casing of the tubular housing, the spring plate having:
a sleeve-like inner collar configured to guide the non-stepped second pin, the sleeve-like inner collar having an annular end face facing the transverse beam in a direction of the inner casing of the tubular housing; and

a wedged piece bent in a direction of the transverse beam and extending from the annular end face of the sleeve-like inner collar, and the transverse beam configured to be held relative to the two surfaces via an annular tip of the wedged piece and the non-stepped second pin configured as an adapter piece arranged between the tappet and the pump piston.
