Claims

[Scope of utility model registration request]

In a device in which an inner filter housed in an index tube of a control rod drive mechanism is attached to a stop piston, a mounting hole is formed in the inner filter passing through the inner filter in the axial direction, and a mounting hole is formed in the upper end of the stop piston. A protrusion is provided, and the mounting protrusion is inserted into the mounting hole, and the upper end of the mounting protrusion protrudes from the upper end of the mounting hole to directly oppose the lower end of the uncoupled rod. An inner filter mounting structure for a control rod drive mechanism, characterized in that a retaining member is attached to the upper end.
