PROBLEM TO BE SOLVED: To provide an operation range measurement device for operation members easily and three-dimensionally measuring an operation range of the operation members.SOLUTION: This operation range measurement device for operation members includes: an operation member substrate 1 and operation members 2 disposed in a matrix state in an X-axis and a Y-axis of the operation member substrate 1, capable of being displaced in a Z-axis direction of the operation member substrate 1, and inserted through the operation member substrate 1. An operator operates spherical bodies 3 each fixed to the distal end of the operation member 2 to three-dimensionally measure an operation range of the operation members 2 by the operator.COPYRIGHT: (C)2014,JPO&INPIT【課題】 操作部材の操作範囲の測定を簡便にしかも3次元的に行うことができる操作部材の操作範囲測定装置を提供する。【解決手段】 操作部材の操作範囲測定装置において、操作部材基板1と、この操作部材基板1のX軸及びY軸方向にマトリックス状に配置され、かつ前記操作操作基板1のZ軸方向に変位可能であるようにして前記操作操作基板1に挿通された操作部材2とを具備し、この操作部材2の先端に固定される球状体3を操作者が操作することにより、操作者による前記操作部材2の操作範囲を3次元的に測定する。【選択図】 図4
