1. A wire electric discharge machine comprising:
a wire electrode supporting device that holds one end portion of a wire electrode; and a wire electrode forwarding device that includes
an aspirator that supplies a fluid to forward the wire electrode from a wire electrode guiding section to a wire electrode collecting section,a rotating body positioned on a path between the aspirator and the wire electrode collecting section, and diverting the forwarding direction of the wire electrode, anda rotation restraining device that restrains rotation of the rotating body rotated by the fluid supplied from the aspirator, wherein the rotating restraining device comprises a brake member that is provided in a rotating body block that rotatably supports the rotating body, and an ejection device that ejects a fluid to the brake member to press the brake member against the rotating body to restrain rotation of the rotating body.
