シール。 A seal is created around the circumference of the rotary shaft inserted into the housing of the aircraft by the biasing force of a coil spring backed up within the casing fixed to the rotary shaft side against a mating ring fixed to the housing side. In a mechanical seal in which rings are axially biased toward the mating ring side and built into slidable contact with each other, a locking piece is protruded from an end surface of the casing facing the seal ring, and the seal ring is fixed to the mating ring. When assembling the seal ring while moving it against the biasing force of the coil spring backed up in the casing, the back surface of the seal ring is brought into contact with the locking piece of the casing, so that the coil spring is always kept in a non-adhesive state. A mechanical seal characterized by being maintainable.
