In an automatic transmission apparatus ( 10 ) for a vehicle provided with a shift lever ( 20 ) manually changing a position of an automatic transmission ( 50 ), a torque detector ( 30 ) for detecting a changing operation force of the shift lever, and an assist force applying means ( 40 ) for applying a backup force to the manual operating force of the shift lever so as to transmit to the automatic transmission via a transmitting means ( 52-54 ), thereby changing to a desired position, a lever base ( 26 ) of the shift lever ( 20 ) is mounted to an input shaft ( 31 a) of the rotation axis ( 31 ) of the torque detector ( 30 ), and an output gear ( 43 ) of the assist force applying means ( 40 ) is mounted to an output shaft ( 31 b) of the rotation axis ( 31 ) of the torque detector ( 30 ), and the rotation axis of the shift lever ( 20 ), the rotation axis ( 31 ) of the torque detector ( 30 ) and the rotation axis of the assist force applying means ( 40 ) are arranged in a line.
