The purpose of this invention is to prevent magnetic flux and electric wave noise leaking from electric motor from affecting the magnetism prevention components of other materials, to reduce the number of assemblies and number to be assembled, and to fulfill reduction of cost. For this purpose, the present invention provides a magnetism prevention structure of a motor assist apparatus for a vehicle, having an electric motor which is directly connected with an engine and consists of a motor rotor and a motor stator, comprising: a rotational position sensor which consists of a sensor rotor and a sensor stator, wherein said motor stator and said sensor stator are each attached to a motor case installed in a cylinder block of the engine. The motor rotor and the sensor rotor are each attached to a rotor installation member that is installed in a crank shaft; and the motor assist apparatus which integrates a magnetism prevention part to prevent magnetic flux and/or electric wave noise leaking from the electric motor from leaking through the motor case between motor rotor and motor stator of electric motor and a signal line connected to the sensor stator of said rotational position sensor and/or the sensor stator.
