カルシールの回り止め機構。 A mechanical seal that seals fluid by sliding a mating ring fixed to a rotating shaft side and a floating seat fixed to a non-rotating housing side to each other, both of the housing and the floating seat, Engagement means that engage with each other are provided, and in the detent mechanism that prevents relative rotation between the two, the engagement means is engaged with the engagement means formed on the floating sheet or the support member of the floating sheet. A knock pin has one end supported by means such as screwing onto a rising surface of a recessed step in the housing inner cavity, and the other end is inserted into a knock pin support hole bored in a surface opposite to the rising surface. A mechanical seal rotation prevention mechanism characterized by being supported by.
