SUPPORT STRUCTURE FOR AUTOMATIC VEHICLE DRIVING DEVICE

An automatic vehicle driving device () including a transmission actuator unit () and pedal actuators () is supported as a whole by a frame () and legs (). The frame () extends obliquely downward from a seat back abutting part () located at an upper end of the frame () toward a vehicle front side. The frame () is provided with the pair of legs () at a top end of the frame (). The legs () extend downward along a front end of a seat cushion () and abut against the vehicle body floor (). By tightening a belt () between the frame () and a seat support (), the frame () is pulled obliquely downward and is firmly fixed. Since a flexible seat cushion () does not bear a load of the device (), vibrations of the device () during a running test do not easily occur.
