Claims

[Scope of utility model registration request]

In a mechanical seal in which a pair of sealing members facing each other have sliding surfaces airtightly supported on the shaft side and the housing side, and the sliding surfaces are pressed against each other and rotated to seal the shaft, a low pressure communicating with the sliding surfaces is used. A mechanical seal that has a water-absorbing material made of a hydrophilic material installed in the side passage, and has the function of absorbing liquid or vapor leaking from between both sliding surfaces and temporarily retaining it inside the mechanical seal.
