PURPOSE:To perform the stable operation of guiding a wire electrode, by providing guides around the wire electrode in such a manner as to divide a guide into a plurality of divisions, pressing and holding the wire electrode from at least one way with the divided guides. CONSTITUTION:Wire guides 21, 22, 23 for guiding a wire electrode 1 reeled and moved are formed by dividing a guide into a plurality of guides around the wire electrode 1. Each of the divided guides 21, 22, 23 is supported in a state press balanced by springs 41, 42, 43 to stably guide the wire electrode 1 without directional quality. |
