An electric wire twisting device is provided, which is capable of producing a preferable twisted electric wire from a plurality of electric wires of which both ends are cut. An electric wire twisting deviceincludes a first gripping deviceincluding a first clampthat grips a first end of a first electric wire CT, a second clampthat grips a first end of a second electric wire C, and a first holderA that holds the first clampand the second clamp. The electric wire twisting deviceincludes a second gripping devicethat grips a second end of the first electric wire CT and a second end of the second electric wire CT, a first revolving actuatorthat causes the first holderA to rotate around a center line of revolution CL, and a first rotating actuatorthat causes the first clampand the second clampto rotate around a center line of rotation that is parallel to the center line of revolution CL or is inclined with respect to the center line of revolution CL.

An example impeller includes: an impeller body in which an internal channel is formed, the internal channel extending inside the impeller body in a direction of a rotation axis spirally about the rotation axis to connect an inlet and an outlet; and at least one centrifugal vane provided in the impeller body. The internal channel including the inlet and the outlet has a predetermined passage diameter. An external channel is formed so as to continue to the outlet and go around the circumferential surface of the impeller body, the external channel being defined by the centrifugal vane and being recessed inward in the radial direction from the circumferential surface of the impeller body. At least a part in a flow direction of the external channel has a channel width in the direction of the rotation axis smaller than the width of the outlet.
