The present invention provides a mechanical seal device (1), capable of sealing special fluid such as chemicals, easy to be mounted to a device and small in size. The mechanical seal device (1) comprises a seal cover (30), a first seal ring (3) axially-movably arranged in an inner circumference side of the seal cover (30), a second seal ring (10) fixed to a rotary shaft (70), a spring (9) arranged in the inner circumference side of the seal cover (30) and pressing the first seal ring (3) in a direction toward the second seal ring (10) and a bellows (5) mounted to the inner circumference side of the seal cover (30) and axially-expandably mounted between the seal cover (30) and the first seal ring (3). The spring (9) is mounted to the seal cover (30) along the axial direction in which the bellows (5) is expanded and contracted. |
