Claims

[Scope of utility model registration request]

The stationary side component supported in an internal fit on the inner periphery of the seal housing and the rotating side component supported in an external fit on the outer periphery of the rotating shaft are connected to the stationary seal ring of the stationary side component and the rotating side component. In a mechanical seal formed into a unit capable of moving in the axial direction in a state in which a rotating sealing ring of a component part is brought into relative rotational sliding contact, a stationary side locking body is held on the outer periphery of a stationary side component part, and the stationary side locking body is rotatably held on the outer peripheral part of the stationary side component part. A stationary side engagement surface extending in the axial direction is formed on the inner circumference of the seal housing, and the rotation side locking body is held rotatably on the inner circumference of the rotation side component, and an axis line is formed on the outer circumference of the rotating shaft. What is claimed is: 1. A rotation prevention device for a mechanical seal, characterized in that a rotation side engagement surface extending in a direction is formed with a notch.
