To provide a posture change jig for changing a posture in a state where an object such as an arch timbering is suspended with a simple structure.SOLUTION: This posture change jig interposed between a crane and an object to change a posture in a state where the object is suspended comprises at least: a body 10; a first wire 20 moored from at least two points of the body 10 to a hook of the crane; a sheave 30 provided in the body 10; a second wire 40 moored at one end to the hook and wound at the midway on the sheave 30; a winch 50 to which the other end of the second wire 40 is connected to be wound up; and a third wire 60 provided in the body 10 to be able to suspend the object. The posture of the object suspended by the third wire 60 can be changed through rotation of the body 10 based on winding-up of the second wire 40.SELECTED DRAWING: Figure 1
