Abstract
A propulsive apparatus for use in an electric vehicle includes a gear rotatable by a propulsive motor and having first teeth, and a constant velocity joint having an outer member which includes a larger-diameter portion having second teeth on an outer wall surface thereof. The second teeth serve as part of a speed reducer mechanism which is thus interposed between the propulsive motor and the constant velocity joint. When the gear is rotated by the propulsive motor, the propulsive power is transmitted through the speed reducer mechanism to the constant velocity joint for rotation.
