Claims

[Scope of utility model registration request]

a fixed seal ring attached to the outer peripheral surface of the shaft; and a fixed seal ring disposed on the axial end side of the shaft,
A fixed housing that surrounds the outer circumferential side of the fixed seal ring and is pressed against the outer circumferential side of the fixed seal ring via an annular elastic member, and a rotary seal that is attached to the outer circumferential surface of the shaft on the bearing side of the fixed seal ring. and a rotating housing connected to the shaft via a bearing, surrounding the rotating seal ring, and press-welded to the outer circumferential side of the rotating seal ring via an annular elastic member, the fixed seal ring and the rotating seal ring. A conical surface for mounting an elastic member is formed on the outer circumferential side of the shaft, and the fixed seal ring and the rotating seal ring are attached to the shaft with sliding surfaces formed on the inner circumferential side in sliding contact with each other, A floating seal device characterized in that each sliding surface is formed in a region closer to the shaft than a line of action in which the load of each of the elastic members acts on each conical surface along the axial direction of the shaft.
