Kind Code:
B2
Abstract:
The present invention is to provide a mechanical seal device capable of suppressing intrusion of grit and dust into a part between a sealing face of a mating ring and a sealing face of a seal ring as far as possible. A mechanical seal device 3 includes a mating ring 30 having an axially perpendicular sealing face 30a and having a flange 31 projecting in a radial direction, an axially movable seal ring 40 having an axially perpendicular sealing face 41a to be brought into contact with the sealing face 30a of the mating ring 30, a resilient member 70 that presses the seal ring 40 to a side of the mating ring 30, and a case 60 inside which the seal ring 40 and the resilient member 70 are accommodated. In the mechanical seal device 3 in which a fluid is sealed by bringing the axially perpendicular sealing faces 30a, 41a of both the rings 30, 40 into contact with each other and relatively rotating the sealing faces, by engaging the case 60 and the flange of the mating ring 30 with each other, the seal ring 40 and the mating ring 30 are resiliently held.
