A sealing device is assembled between a cylindrical housing and a rotor located inside the housing coaxially with the housing and rotatable about an axis. The sealing device includes a first seal and a second seal. The first seal includes a body to extend along an outer periphery of the rotor, a port through the body in a radial direction of the body, and a groove on an outer circumferential surface of the body, surrounding the port when the outer circumferential surface is viewed in the radial direction, and including a pair of slopes flaring toward the housing. The second seal is attachable to the groove to be in contact with the pair of slopes and seals a gap between the housing and the first seal.
