To attain the aforesaid objective, the present invention provides a distributor in which is accommodated a magnetic rotating member which rotates in synchronization with the rotation of the crankshaft of an internal combustion engine, the improvement comprises said distributor is provided with an air vent portion having a magnetic trap means. Any dust carried in air drawn into the distributor from the outside for ventilation purposes will not penetrate to the interior but will be caught by the magnetic trap means.
This type of angle-of-rotation sensor is usually accommodated in a bearings distributor, but when the distributor is equipped with an air vent, there is a risk that particles such as of dust and metal, and foreign matter, may enter the distributor via the air vent and adhere to the magnetic rotating member of the sensor, thereby causing changes in the magnetic characteristics of the rotating member that render accurate detection of crank angles impossible.
