摘要： To prevent falling away of a backup ring (3) from a main lip (12) when uninstalled to a device and prevent inverse assembling, a sealing device is provided with an attaching ring (11), a main lip (12) integrally provided on an inner periphery of the attaching ring, and a backup ring (3) supported to a backup ring support portion (15) formed on an inner periphery of the main lip (12) so as to be positioned at an atmospheric air side than a sliding surface with a shaft, the backup ring support portion (15) and the backup ring (3) are fitted to each other with their fitting surfaces (15a, 31a) which become smaller in diameter relatively toward an outer side in an axial direction, whereby the backup ring (3) is fitted to the backup ring support portion (15) and has directionality in the fitting surfaces (15a, 31a).
