置。 A center bending type shield excavator includes a center bending amount detection rod whose base end is attached to the front shield via a universal joint and having a pointer at the tip, a guide member attached to the rear shield, and the center bending amount detection rod. The tip of the rod is supported by the guide member so as to be movable parallel to the axis of the rear shield,
and a connecting member for guiding, and a scale plate attached to the guide member, so that the amount of movement of the tip of the center bending amount detection rod accompanying the center bending operation is indicated by the pointer and the scale plate. A bending amount detection and instruction device for a shield excavator, which is characterized by:
