PROBLEM TO BE SOLVED: To understandably display an axial condition of an external sensing means of a radar device or the like, by utilizing an existing meter visibly provided in a car room. SOLUTION: A scale of 90 km/h of a speedometer 33 is made a reference scale 36r, when a pointer 32 is deviated to a right side from the reference scale 36r, it is displayed that an axis of an external sensing means is deviated 0.1 deg. to a right side per one scale, and when the pointer is deviated to a left side, it is displayed that the axis is deviated 0.1 deg. to a left side per one scale. A scale of 4000 rpm of a tachometer 35 is made a reference scale 37r, when a pointer 34 is deviated to a right side from the reference scale 37r, it is displayed that the axis of the external sensing means is deviated 0.1 deg. to an upper side per one scale, and when the pointer is deviated to a left side, it is displayed that the axis is deviated 0.1 deg. to a lower side per one scale. When an axial deviation in a vertical/lateral direction is generated in a permissible range of±0.5 deg., a lamp in the left end of an inter-vehicle distance display lamp 39 is lighted to inform completion of aiming.
