Abstract:
1. An angle measuring device for measuring an angle formed between a measured line connecting a first position and a second position on a body and a predetermined reference line by using a sensor capable of detecting the angle, the angle measuring device comprising: a first pointing device for pointing to the first position; a second pointing device for pointing to the second position; a first holding device for holding the first pointing device; a second holding device for holding the second pointing device; a moving mechanism that allows the first holding device and the second holding device to be movable so that a line segment connecting the first pointing device and the second pointing device and the measured line are on the same plane; and a relative position indicating section that indicates relative positions of the first pointing device and the second pointing device; the moving mechanism including a first turning mechanism and a second turning mechanism; the first turning mechanism allowing the first holding device and the first pointing device to be turnable about a position away from the first position; the second turning mechanism allowing the second holding device and the second pointing device to be turnable about a position away from the second position; the relative position indicating section including a first angular scale mark and a second angular scale mark; the first angular scale mark indicating a turned amount by the first turning mechanism associated with the first pointing device; and the second angular scale mark indicating a turned amount by the second turning mechanism associated with the second pointing device.
