PURPOSE: A connecting structure between a drive motor and a transmission of a non-contact electromagnetic inductive charging type electric vehicle is provided to improve output efficiency by absorbing a shock generated between a drive motor and a transmission. CONSTITUTION: A coupling unit(300) absorbs a shock generated between a motor shaft of a drive motor and a transmission shaft when the power is transmitted. A coupling unit(300) includes a motor shaft connection part(310), a connection link(320), and a coupling ring(330). The motor shaft connection part is connected to the motor shaft of the drive motor. The connection link is coupled with the motor shaft connection part so as to transmit the torque of the motor shaft connection part to the transmission shaft without the shock. The coupling ring is formed to couple the connection link with the motor shaft connection part.
