PURPOSE:To contrive to reduce the size and weight of a distributor and enable to ignite securely by a method wherein a distributor rotor rotated as one body with the shaft of the distributor can be moved relative to a side electrode for a distributor cap by a centrifugal force arising from the rotation. CONSTITUTION:A weight 19 flown outward with a pivot shaft 18 as an axis by the centrifugal force arising from the rotation of the shaft 2 is provided at a plate 17 which is clamped to a bearing part 12 integral with the shaft 2. The weight 19 is provided with a rod 20 which is engaged with a guide bush 22 made of an abrasion-resistant metallic material or the like at a part of the distributor rotor 21 in such a manner that the rod 20 can slide with an appropriate clearance. Under the centrifugal force according to the revolution speed of the shaft 2, the weight 19 flies outward with the pivot shaft 18 as an axis to such a position that the force of a spring 24 is balanced. The rotor 21 is rotated by the rod 20 in the rotating direction (a) of the shaft 2 in an integral manner and with an amount of advance corresponding to the amount of the flying motion of the weight 19. Accordingly, the facing of the rotor 21 and the side electrode 15 can be corrected sufficiently. |
