A seal structure for an in-wheel electric motor drive system. The seal structure is used for forming a seal between a first sealed portion (90s) of an output shaft and a second sealed portion (10s) of a housing. The seal structure (1) comprises a dustproof ring (11) and a seal assembly (12). The dustproof ring (11) is used for being fixed to the first sealed portion (90s); the dustproof ring (11) extends radially outwards, so that the dustproof ring (11) and the second sealed portion (10s) form a labyrinth seal structure (1); the seal assembly (12) is used for being fixed to the second sealed portion (10s); and the seal assembly (12) is provided with a plurality of lips extending towards the first sealed portion (90s) and/or the dustproof ring (11), and is used for blocking the communication between the labyrinth seal structure (1) and the interior of an in-wheel electric motor drive system, thereby greatly reducing the probability of the lips of the seal assembly being damaged due to water freezing after same enters the position where the seal assembly is located. Further provided is an in-wheel electric motor drive system comprising the seal structure.
