The neutron beam shutter system of JSNS, which has 23 beam ports, at J-PARC has a particular design that enable all the beam shutter to behave independently. This unique feature is realized by adoption of an electric servo motor system using compact ball screw jack. We have paid attention on workability of maintenance in a little space of a neighboring drive assemblies, barycenter of every shutter gate including its insert, and so on. We have carried out off-beam commissioning in middle 2007, and validated our design of shutter system in detail, including maintenance method.
