PROBLEM TO BE SOLVED: To provide an orientation direction measuring device allowing an operator efficiently to check an orientation direction of an antenna in a short time in a maintenance for registration of a wireless station.SOLUTION: An orientation direction measuring device 1 includes a planar mirror plate 40, a base plate 10 composed of a planar transparent member, a compass 20a fixed to the base plate 10 and indicating an orientation on the base plate 10, and a protractor 20b attached rotatably centering around the compass 20a. The base plate 10 is provided with a scale 14 in a grid shape displayed thereon at an area in a vicinity of the compass 20a. The scale is composed of multiple vertical lines 14a and transverse lines 14b that are parallel to each other, respectively. A base line 14c that is specific one of the multiple vertical lines 14a and transverse lines 14b passes through the center of the compass 20a. The mirror plate 40 is provided on the base plate 10 and mirrors a measurement object of an orientation direction in the area where the scale 14 is displayed.SELECTED DRAWING: Figure 1 |
