のである。 Next, the operation of this embodiment will be explained. When the engine is operated and the drive shaft 6 is rotated, the rotor shaft 14 and therefore the signal rotor 21 are rotated via the centrifugal advance mechanism G. And signal rotor 21
When each protrusion 21a faces the tip e of the iron core 26 in the pulse generator P, the magnet 2
5, iron core 26, signal rotor 21, rotor shaft 1
4. Magnetic transmission plate 29, inner ring 22b, support fittings 24
A magnetic flux is formed between the signal rotor 21 and the magnet 25, and then the protrusion 21a of the signal rotor 21 and the iron core 26
Since the magnetic flux changes as the tips e of the two discs shift, a pulse-like voltage is generated in the pickup coil 27. That voltage operates the ignal iterator unit 54 to cut off the primary current flowing through the primary coil 46 of the ignition coil 33;
Next, a high voltage is generated in the coil 48, and the high voltage is distributed to the corresponding side electrodes 31 via the high voltage terminal 51, conductive element 63, conductive rod 61, center electrode 32 and power distribution electrode 30, and sparks the ignition plug. It is something.

で、これによつても点火時期が進角される。 This ignition timing is determined by the rotation of the drive shaft 6 being transmitted to the rotor shaft 14 via the centrifugal advance mechanism G and the rotation speed of the signal rotor 21 being accelerated. The angle is advanced by shortening the time from one facing position to the next facing position. Further, since the inner ring 22b of the bearing 22 is rotated by the vacuum advance mechanism V, the ignition timing is also advanced by this.

心振れを起こすことがない。 In this case, the recess 51a of the high voltage terminal 51 is surrounded by a cylindrical portion 49b;
Since the creepage distance is longer on the outer peripheral surface, creeping discharge along the outer peripheral surface of the case 49 of the high voltage terminal 51 is prevented. Further, since the drive shaft 6 is supported by the bearings 7 and 8 in a double-sided manner, the drive shaft 6 does not run out.
