ABSTRACT:
A structure for connecting electrodes of a motor unit and a motor driver unit which is a power circuit for the motor unit in an electric power drive vehicle, so that the motor unit and the motor driver unit are electrically connected to each other, includes: electrode terminals to which a coil of the motor unit is connected and which are provided with fixing nuts; substantially L-shaped electrode plates each formed at one end with a terminal portion connected to the inverter circuit and at the other end with a contact portion to which the electrode terminal is connected, the contact portion being formed with an insertion hole; L-shaped resin electrode bases for attaching the electrodes plates to a metallic frame under an insulated condition, each of the electrode bases including an elongated hole for attaching a bolt to be engaged with the insertion hole of the electrode plate and a guide groove for preventing the electrode plate from rotation; and bolts each extending through the elongated hole of the electrode base so as to connect the electrode terminal to the electrode plate.
