An operator state determining device is provided, which includes an image pick-up device disposed inside a vehicle cabin, and configured to image an operator from the side, a torso angle detector configured to detect an operator's torso angle, a posture measuring module configured to measure a head-pitch angle change that is a difference between a head-pitch angle of the operator before the operator becomes unconscious and a head-pitch angle of the operator after the operator becomes unconscious, based on the image, a memory configured to store a given turnout angle and a given head-pitch angle change, and an abnormality determining module configured to determine an operator's abnormality. The abnormality determining module determines that the operator is in an abnormal state when an initial torso angle before becoming unconscious is inclined rearward more than the turnout angle, and the head-pitch angle change is greater than the given head-pitch angle change.
