FIXING TOOL FOR OPTICAL FIBER CABLE SENSOR MEASURING DEVICE

PROBLEM TO BE SOLVED: To provide a fixing tool for an optical fiber cable sensor measuring device having excellent workability, capable of improving greatly an installation or fixing work, and coping with a problem wherein necessity for rewinding a fiber or refastening the fiber by moving it on a reel occurs comparatively frequently. SOLUTION: A pair of fixing tools for the optical fiber cable sensor measuring device for sandwiching a measuring object and fixing it on two points relative to an optical fiber cable having FBG, and measuring displacement of the measuring object has characteristics wherein each fixing tool is equipped with a mounting pedestal provided with a hollow part bent approximately in a recessed shape on the center in the longitudinal direction, a hinge-shaped connection member with one end side mounted on a mounting pedestal surface part, and an optical fiber cable fixing member mountable on/dismountable from the mounting pedestal by using a rotation part of the connection member as a shaft. The optical fiber fixing member has a rotation base part having an approximately cylindrical shape, and a ring-shaped optical fiber cable winding part mounted on a rotation base part and having a sliding prevention rough surface formed on the outer peripheral surface.
