ABSTRACT:
The present invention relates to a device for optically monitoring or detecting information regarding a moving object by using optical fibers. The object of the invention is to prevent output characteristics from deteriorating with the passage of time. This deterioration is caused by the fact that a resin-made holder of a detecting section is deformed or a position in which the holder is installed shifts particularly because of heat and vibrations. An intermediate member is disposed between the holder and a fixing member. The holder is secured to the intermediate member which is used as a member for absorbing heat and vibrations.
