Abstract
A filter outer cylinder container is a hollow container, and a filter medium is mounted in the container. Fluid passage holes, opened in a side surface member of the filter outer cylinder container, are located at or above a fixed height from a bottom portion of the filter outer cylinder container, whereby a machining liquid is stored in the filter outer cylinder container, so that the filter medium can be always submerged in the machining liquid.
