According to the invention, a retarder for attachment to a transmission is proposed, which retarder comprises a housing device (12), which encloses a retarder oil chamber (7), and a shaft (2), which has a first portion (13) on which a rotor is arranged for conjoint rotation and a second portion (14) on which a step-up mechanism toothed gear (3) is arranged for conjoint rotation. The first portion is positioned in the retarder oil chamber and the second portion projects into the transmission oil chamber, wherein a sealing element (5) is arranged between retarder oil chamber and transmission oil chamber such that these are fluidically separated from one another. To improve operational reliability, it is proposed that, in the shaft, a channel (8, 9, 10) is provided via which oil can be conducted from the transmission oil chamber to the sealing element.
