Abstract
A bidirectional driving mechanism 10 has a drive-side linkage rod 11, a driven-side linkage rod 13, two levers 12 that link the drive-side linkage rod with the driven-side linkage rod, and a guide 14 that regulates the operation of the drive-side linkage rod 11 and the driven-side linkage rod 13. A moveable pin 18 is passed through a first groove cam 16 of the drive-side linkage rod 11, a second groove cam 17 of the guide 14, and third groove cams 19 of the levers 12, and by operation of the drive-side rod 13, the moveable pin 18 moves within the respective groove cams 16, 17, 19, causing the levers 12 to rotate, the driven-side linkage rod 13 to be driven in a direction opposite to the drive-side linkage rod 11, and a driven-side arc electrode 5 to be driven in a direction opposite to a drive-side arc electrode 4.
