Claims

[Scope of utility model registration request]

An ignition coil disposed in a housing, a drive shaft supported by the housing and rotated in synchronization with the crankshaft of the internal combustion engine, and a vane made of a magnetic material provided on the drive shaft and rotated together with the drive shaft. and a unit which is provided in the housing and integrally includes a Hall effect sensor device having a magnetic sensor and a magnet, and a power transistor, and a unit which is attached to the ignition coil side of this unit and which dissipates the heat generated by the power transistor. A power distribution device for internal combustion engine ignition, comprising: a heat dissipation plate that emits heat to the outside; the vane passes through a gap between the magnetic sensor and the magnet; and an electrical signal is generated to the Hall effect sensor device; is an internal combustion engine ignition power distribution device characterized by being composed of a magnetic material.
