The invention relates to the filtration devices, in particular to the oil coarse filters of the internal combustion engine. The oil coarse filter of the internal combustion engine contains a body, separated into two isolated from each other sections: for unrefined and refined oil, filtering devices placed into the body, each including a stack of round plates, fixed onto a vertical shaft, and a pillar adjacently mounted to the latter, with knives-scrapers fixed thereto in tiers and placed into the round plate clearance, and a mechanism of vertical rotation of the shaft. The filtering devices are mounted into the body in two rows, and the rotation mechanism contains a worm shaft, set in motion by a handle with the help of the gearing and placed between the rows of filtering devices, and engaging into mesh with some worm wheels, each wheel being fixed in the superior part of the shaft of each filtering device. Each filtering device may be equipped with a safety clutch, installed onto the vertical shaft above the worm wheel. Claims: 2Fig.: 2
