In a valve train (1) of an internal combustion engine (10), a tappet push rod (2) comprises on its first end (3), a tappet (5) and an uncoupling device (8) made as a single component, and on its second end (4), a hydraulic lash adjuster (15) that acts on a rocker arm. Due to this spatial separation of the lash adjuster (15) from the single component (5, 8), a component (5, 8) is obtained that has a reduced mass and a smaller diameter as well as a relatively simple structure. In addition, the lash adjuster (15) can now be supplied with hydraulic medium directly out of the rocker arm.
