Is adjusted along the longitudinal direction of the pair of rail members 121.
Is maintained at a predetermined size, and in this state, the mounting position of the gauge body 125 is adjusted along the direction orthogonal to the longitudinal direction of the base body 128 by the operation of the second position adjusting means.

In this embodiment, the pair of grips 12
In a state where the rail members 121 are gripped by the rails 6 and 127, the rollers of the gripping parts 126 and 127 are in a state of being able to roll on the rail members 121, so that the centered rail member 121 is moved up and down via the rail bracket. When fixing to the road, the centering device can be moved in the vertical direction of the hoistway without releasing the gripping state of the rail member 121, and the centering operation of the rail member 121 can be performed from this point. It can be performed efficiently.
