The invention proposes a deactivating element (1) for a valve train of an internal combustion engine. The deactivating element (1) comprises a housing (2) and an inner element (4) that is axially displaceable in the bore (3) of the housing (2). According to the invention, the pistons (7) arranged in the inner element (4) for coupling into an annular groove (12) in the housing (2) possess two flattened regions (10, 15) arranged diametrically opposite each other in axial direction of the deactivating element (1). The height of the annular groove (12) is reduced by a measure of a height of the second, additional flattened region (15). Due to the reduction of height of the annular groove (12), its volume is also reduced. This results in advantages activation and deactivation times.
