Provided is a small mechanical seal device which can efficiently wash a sealing surface, and can appropriately seal a sealed fluid and a quenching liquid. In a mechanical seal device (1), two sealing surfaces, i.e., an objective fluid sealing surface (131) and a quenching fluid sealing surface (132) are formed in a stationary sealing ring (130), and a quenching fluid passes through a sealing groove (133) provided between the sealing surfaces. Quenching bores (134) which penetrate through the stationary sealing ring (130) in the axial direction are formed in the stationary sealing ring (130). The quenching fluid passes between an intermediate chamber (C) provided on the back side of the stationary sealing ring (130) and the sealing groove (133) via the quenching bores (134). |
