装置。 A plurality of chuck claws are disposed on the substrate so as to be able to slide freely in the radial direction with respect to the center line of the held object, and horizontal racks along the sliding direction are provided, and vertical racks are interlocked and connected to these horizontal racks via pinions. An operating body with a rack attached in a direction crossing the sliding direction of the chuck pawl is provided so as to be movable in the vertical rack direction, and a shaft body in the vertical rack direction connected to this operating body via a screw mechanism is moved in the vertical rack direction. The shaft is arranged to be movable and rotatable around an axis, and a rotation drive device for opening and closing is connected to this shaft, and a biasing means is provided for biasing the shaft toward the approaching movement side of the chuck pawl. A holding device characterized in that it is provided with a control means for detecting a shaft body moving toward the approach movement side of a chuck pawl against a biasing means and stopping the rotary drive device.
