Abstract:
PROBLEM TO BE SOLVED: To provide a detection device that can be attached to a blade in a prescribed positional relationship in respect to the blade.SOLUTION: The detection device comprises: a first member having a rotating shaft, rotatable around the rotating shaft, connected to a blade long in a direction parallel to the rotating shaft and rotated around the rotating shaft together with the blade; a second member connected to the first member, having a first mark indicating a position related to a rotating direction around the rotating shaft and rotated together with the first member around the rotating shaft; and a detector which comprises: a shaft member connected to the second member, having a second mark indicating a position related to the rotating direction and rotated together with the second member around the rotating shaft; and a body member for rotatably supporting the shaft member. The detector outputs a reference value when the shaft member is arranged at a reference position in respect to the rotating direction, and the shaft member is connected to the second member in such a way that the position of the first mark and the position of the second mark may coincide to each other in respect to the rotating direction.
