In particular, the present invention relates to a power distributor having a structure suitable for assembly, waterproofness, and vibration resistance.
従来の点大コイル一体形配電器は、特公昭６〇−１ｇ８
３４号に記載のように、ハウジングの側部に点火コイル
を取り付け、配電器軸方向に対して直角方向からネジ止
めし固定する構造となっていた。The conventional large point coil integrated power distribution device is
As described in No. 34, the ignition coil was attached to the side of the housing and fixed by screwing from a direction perpendicular to the axial direction of the power distributor.
