A simulation system predicts a behavior of a molten resin in a mold in filling, packing, and cooling processes by using a fundamental equation formulated by the finite element method, and shrinkage factors in a direction of thickness and planar directions based on anisotropy of a volume shrinkage factor obtained during prediction of the filling, packing, and cooling processes, so that a warp deformation in an injection-molded article can be predicted at a higher precision. In this simulation system, the warp deformation is predicted by calculating the shrinkage factors in accordance with:

Disclosed is a motor having a rotor driven by a vibrator generating a vibration of rope skipping motion. The rotor has a friction portion which is in contact with the friction portion of the vibrator so as to be given the vibration of rope skipping motion by the friction portion of the vibrator, and a supporting portion which is provided at a position spaced apart from the friction portion and which is in contact with a portion of the vibrator. Thus, the motor is constructed compactly.
