Abstract
A select lever device for an automatic transmission includes: a torque sensor to detect an input torque to a drive shaft of a select lever; a select position sensor to detect the stroke angle of the select lever; a characteristic data storing unit in which a mechanical load characteristic of the select lever is stored; and a control unit to which signals and data of these elements are inputted. Further, the control unit includes an electric motor to output to the select lever assist torque for assisting the operating force by a driver, the assist torque being controlled based on the input torque to the select lever, the stroke angle of the select lever, and the mechanical load characteristic of the select lever.
