Abstract
An electric motor vehicle includes a motor case having first and second hollow section, with the first hollow section having a smaller diameter than that of the second hollow section, forming a step between the first and second hollow sections; a stator provided in the second hollow section and having an end engaged with the step; a motor cover having a cylindrical projection in sliding relationship to the second hollow section and sufficiently long to press the stator against the step and provide a space between the motor case and the motor cover for a minimum thickness of the stator; and a filler made of a liquid packing provided in the space between the motor case and the motor cover for sealing the motor against winds and rains.
