To make compact a wire-twisting machine that twists wires four times.

First to fourth wire-twisting guides D1-D4 are arranged in proximity to first to fourth turn-rollers B1-B4 respectively. Each of wire-twisting guides D1-D4 is turned around a center line M while being integrated with each of turn-rollers B1-B4 respectively. The first and second turn rollers B1, B2 and the first and second wire-twisting guides D1, D2 are turned in the same direction, and the third and fourth turn-rollers B3, B4 and the third and fourth wire-twisting guides D3, D4 are turned in the direction reverse to that of the first turn-roller B1 etc. The four turn-rollers B1-B4 are disposed on the center line M, which connects a twist opening die A and a twisted-wire winding part C, under the positional relationship, so that the path for routing the twisted wire is shortened.
