Abstract
A through section shielding construction is disclosed in which a partitioning wall defines a slit-like opening extending along a lateral direction as a moving passage of a penetrating member relative to the partitioning wall, and a plurality of shielding plates for closing the slit-like opening are juxtaposed along the slit-like opening as being suspended pivotally to be pushed open one after another by the penetrating member moving along the slit-like opening. The shielding plates are provided as adjacent pairs, and there is provided an operative coupling mechanism for operably coupling, with each other, two shielding plates constituting each pair in such a manner that in association with one of the paired shielding plates being pushed open in one direction by the penetrating member, the other shielding plate is pivotally opened in the opposite direction to the one direction.
