A housing structure of a distributor for an internal combustion engine including an ignition coil is disclosed. The housing structure comprises a cup-shaped base accommodating the ignition coil and a cap fitted thereon and accommodating a distributor rotor. A cap-shaped partitioning cover is disposed between the base and the cap to separate the distributor rotor portion therefrom. The high output voltage of the ignition coil is supplied to the distributor rotor through a hollow cylindrical tower fixed to the ignition coil and an insertion electrode which is integral with the cap and fits into the hollow cylindrical tower. The cover has a cap-shaped side extension having a annular disk-shaped top which passes through the insertion electrode. A sealing member, which is disposed between the side extension of the cover and the top portion of the high-voltage tower, includes a portion tightly held between the top end of the tower and the top annular disk of the cap-shaped side extension, and a surface tightly pressed against the side surface of the insertion electrode.
