NOVELTY - The vehicle has a rear body (12) with rear body frames (19) attached in a transversely tiltable manner with respect to the body frame. A chassis (17) is attached to the rear body frame through a pivot shaft on a vehicle forward side in a vertically swingable manner. A motor control device (37) which serves as a battery control device is located on the vehicle forward side of the battery case (48). A contactor (18) which has a function to open and close a connection between the batteries (BF,BR) and the motor control device is located on the lateral face of the battery case.    USE - Electric three wheeled vehicle.    ADVANTAGE - The size of the battery case located on a rear body can be small and the number of components can be decreased. The motor control device is located outside the battery case and at the front of the rear body such that it is easily cooled by a wind during a run. This eliminates the need for installing an electric fan for cooling the motor control device so the body structure can be simplified and the number of components can be decreased. The motor control device and the contactor are close to each other such that the length of a high voltage harness for connecting them is shortened. Using the space created by a level difference on the bottom of the battery case effectively, the down regulator can be installed in a way not to cause interference with the chassis. The front battery can be installed in a lower position while providing a sufficient clearance to prevent interference between the chassis and the battery case even when the chassis swings vertically to lower the center of gravity of the vehicle body. The down regulator is attached to the bottom of the battery case such that the wire for connecting the battery charge port and the down regulator can be shortened. The mounting surface of the board housed on which various electric components are mounted is oriented toward the vehicle forward direction so that the motor control device is less susceptible to transverse tilting motion of the rear body frames and is cooled more stably.
