In a wire guide device for a wire electrodischarge machine, a holder member has at least an insertion path permitting insertion of wire electrode and a wire guide forming part of the insertion path. A housing holds the holder member and a guide holding sleeve is provided at the holder engaging part of the housing and resiliently holds the holder member by a device for a working fluid. A groove provided between the guide holding sleeve and the holder engagement part and forms a closed path for sealing the working fluid, and a pressure regulating device provided in the housing communicates with the groove. A positioning device positions the holder member with respect to the housing, around the electrode. A stylus shaped cleaning member (element 75) is used to remove chips deposited near the inner end of tapered cooling apertures to eliminate clogging.
