Claims

[Scope of utility model registration request]

A floating seat, which is a rotating ring, is fitted onto the stepped part of the impeller which is fixedly attached to the shaft via a cushioning rubber;
In a mechanical seal that seals fluid by closely sliding with a seal ring that is a fixed ring fixed to the housing side, the shaft hole of the buffer rubber is made slightly smaller in diameter than the shaft, and the buffer rubber is crimped onto the inner periphery of the shaft hole. A mechanical seal characterized by forming a lip part that becomes
