Claims

[Scope of utility model registration request]

A first magnetic member fixed to the rear extension of the drawer housed in the main body of the reactor control instrumentation panel, and a U-shaped second magnetic member fixed to one side of the support member fixed to the main body. and a U-shaped permanent magnet rotatably supported on a shaft fixed on the other side of the support member at right angles to the end surface of the second magnetic member and provided with an operating rod. The first magnetic member is arranged so that it can move in and out of the recessed part of the second magnetic member, and the end face of the permanent magnet is selectively opposed to and close to the end faces of the first and second magnetic members. A drawer device for a nuclear reactor control instrumentation panel, characterized in that:
