A selector actuator is provided with two controlled attraction parts (5, 6) and three non-controlled attraction parts (7, 8, 9). In the controlled attraction part (5), two magnetic coil poles having attraction sites (16a, 16b) at their top ends are arranged with a magnet in between them. In the non-controlled attraction part (7), three yokes (32a, 32b, 32c) having attraction sites (33a, 33b, 33c) at their top ends are arranged with two permanent magnets (31a, 31b) sandwiched in between them. The controlled attraction part (6) and the non-controlled attraction parts (8, 9) are similarly arranged, respectively. Each magnetic coil pole is arranged to oppose to the ends of two yokes of the same non-controlled attraction part. Hence the magnetic flux leaking from the yoke to the magnetic coil pole flows in a direction substantially perpendicular to a direction in which the attraction site of the magnetic coil pole attracts knitting members, and the magnetic flux leaking from the yoke does not affect needle selection.
