Abstract
An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, a mechanically connecting means connecting them, and an assist actuator to apply assist force to a select lever of the select lever unit. A control unit for controlling the actuator is electrically connected to an operating state sensor detecting an operating state of the select lever. The control unit executes assist control to control the assist actuator based on the operating state signal of the operating state sensor, and maintains the assist control for a predetermined period after the ignition switch is turned to OFF.
