PURPOSE:To enable the whole dust sampler to be downsized by connecting each unit with circulationable connection parts and arranging the wires and pipes connecting the units nearby. CONSTITUTION:A plurality of sampling units 1 are assembled in parallel and combined at the corners near the back ends with circulatable connection parts. The wires 6 and pipes 7 connecting to the sampling units 1 are arranged near the connection part 2 with marginal width so that the units 1 are circulationable. In normal utilization, each unit 1 is arranged in a row and neighbouring units are connected and fixed with fixing metal parts 10. During an inspection and operation of the units 1, the connection with the fixing metal parts 10 is dissolved to open the units 1 and space is produced between the units for working. By arranging the wires 6 and pipes 7 near the connection part 2 as this, their lengths are shortened, the space occupied for the excess length is reduced and thus the total downsizing becomes possible.
