Classical model of helium atom is numerically studied. The phase space is investigated with several types of configurations. While most of orbits cause autoionization via chaotic transients, three types of tori are found. One type of torus is quantized semiclassically with the EBK scheme. Chaotic motion due to the strong interactions between electrons is always unbounded and leads to autoionization. Complex structure of phase space with tori and unstable autoionizing orbits is studied.
