ABSTRACT:
A distributor for a contactless ignition apparatus of an internal combustion engine is disclosed. An ignition control circuit unit of contactless type is comprised of a case containing the ignition control IC circuit and a mold resin of the pick-up coil integrally formed with the case. The distributor contains closed magnetic circuit-forming means comprising a distributor shaft rotatable in synchronism with the engine, a reluctor or rotor fixed on the shaft and having claws in the number corresponding to the number of engine cylinders, a stator having a pair of claws opposed to the claws of the reluctor and mounted on the movable base of the angle advancer for advancing the ignition timing in response to a negative vacuum pressure, and a permanent magnet for generating a closed magnetic circuit through the reluctor stator and shaft. The pick-up coil of the ignition control circuit unit is arranged to cross the closed magnetic circuit, which unit is fixed within the distributor.
