Abstract

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 (31a) 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 (31b) 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.
