上部旋回式車両の方向表示装置。 In an upper revolving vehicle in which the upper revolving body is installed on the lower traveling body via a revolving device, multiple proximity switches are fixed in equal directions at circumferential positions with the same radius from the center of rotation on the lower surface of the upper revolving body. Further, a detectable semicircular donut-shaped dog member of the proximity switch is fixedly provided on the front half side of the lower traveling body at a circumferential position on the upper surface of the lower traveling body corresponding to the circumference, and The circumference of the body is divided into multiples of the total number of proximity switches, and an identification code is set that can be identified by the on/off operation signal of each proximity switch in each of the divisions when the revolving upper structure rotates; A liquid crystal display is provided in the driver's cab, and the liquid crystal display and the proximity switch are connected via a controller, and a plan view image of the undercarriage body corresponding to the identification code can be displayed on the liquid crystal display. A direction display device for an upper-swivel vehicle, characterized in that:
