Disclosed is a barrier unit provided with: a screw hole (211) for a screw (11) to go through; a base section (2) fixed to an object by the screw (11) going through the screw hole (211); a sliding section (3) attached to the base section (2) in a manner allowing sliding; and an external barrier (4) that is attached to the surface of the sliding section (3) that is opposite to the surface thereof attached to the base section (2), said external barrier permanently covering the base section (2) and sliding section (3) from the point of view of the attached side. At one or more of the positions to which the sliding section (3) can be slid with respect to the base section (2), said sliding section does not intersect a cylindrical region which extends in the direction of a line going through the screw hole (211) and the outer edge of which goes through the rim of the screw hole (211).
