Corner seal for rotary piston engines comprising a substantially cylindrical body which is formed with a groove for accommodating an end of the apex seal. The corner seal has an end surface adapted to be brought into a slidable engagement with the inner surface of a side housing. The end surface of the corner seal is formed with a recess so that the area of the sliding surface is decreased to 45 to 75% of a sum of the area of the sliding surface and the area of the recess.
