  By providing such an elevator position detection device and a method for mounting the position detection device, the position detection body and the detected body are positioned in a temporarily fixed state while the gap between the position detection body and the detection target is visually observed. In addition to being adjustable, it is possible to adjust the position while confirming the presence or absence of mutual electrical coupling.

  In addition, it is possible to adjust the position of a plurality of position detectors, which has not been conventionally performed, and it is possible to more reliably adjust the position of the elevator position detector.

  Moreover, the difficult work of adjusting the position immediately before the position detection body and the detection target body are permanently fixed, which has been performed by attaching the conventional position detection apparatus, is unnecessary.

  In addition, it is possible to prevent a positional shift when the position detection body and the detection target body are permanently fixed, which has been easy to occur in the past.

  Since the position adjustment of the position detection body and the detection object is performed by the movement of the adjustment screw, more precise position adjustment can be easily performed.

  In addition, since the adjustment jig adjusts the position detection body and the detection object in a fixed state, an accident such as dropping of the jig can be prevented.
