PROBLEM TO BE SOLVED: To provide a reflection target device 1 for measurement that has a light weight and a small size and is easily carried with a dedicated storage case while securing a large elevation angle range of a reflection prism 10.SOLUTION: In the reflection target device 1 for measurement, a flat outside surface 9a is formed on a casing 9. Therefore, when a reflection prism 10 is rotated upward, the flat outside surface 9a does not become an interference object against a pole 2 in a midway, and a margin occurs in the upward rotation. Therefore, the vertical rotatable range of the reflection prism 10 with respect to the pole 2 is increased, and a large elevation adjustable range &phgr; can be obtained. As a result, even when there is a large elevation difference between a mechanical point and a measured point, the observation point distance (distance between the mechanical point and the measured point) can be measured with no difficulty.SELECTED DRAWING: Figure 4 |
