| Zusammenfassung: | The utility model relates to a sealing device, which aims to restrain the reduction of sealing performance in a low-temperature environment. An elastic body part (20) attached to the metal ring (10); and a pressing ring (30) which is an annular member. The elastic body part (20) is provided with a sealing lip (21), the sealing lip (21) is an annular part protruding towards the inner side, the sealing lip (21) is provided with a sealing lip front end part (22), and the sealing lip front end part (22) can be in contact with a shaft of an installation object. The pressing ring (30) extends along an annularly extending virtual line (v), is mounted so as to face away from the seal lip tip (22), and applies a pressing force, which is a force for fastening the shaft, to the seal lip tip (22).
