PURPOSE: To enable abrasives to be washed immediately after the abrasives are transferred into an abrasive washing device by introducing the abrasives below a tubular polishing device body as well as pinballs separated by a first pinball-abrasives separating unit and providing an abrasive taking-out lid in a second pinball-abrasives sorting unit.

CONSTITUTION: A pinball-abrasives taking-out port 22 is provided openably and closably on the way of a tubular polishing device body 1. A pinball- abrasives sorting unit 24 for separating the pinball from the abrasives sent from said port 22 along with the opening motion of said port 22 is provided. The pinballs (a) separated by said unit 24 are introduced below said body 1 and said unit 24 is provided with an abrasive taking-out lid 27 for taking out the abrasives b' separated in the unit 24 to be washed to the outside, so that only opening operation of said taking-out port 22 provided on the way of the tubular body 1 will do before the stained abrasives are taken out and washed. That is, the pinballs and abrasives are sifted by a machine and only abrasives b' to be washed can be taken out of a pinball polishing machine.
