Claim:
1. A surface treating apparatus for electroplating, comprising: a transport hanger that transports a thin processing object; a plating tank having a tank body that stores a plating solution; and a rise-and-fall mechanism that lowers the transport hanger loaded with the thin processing object into the plating tank and lifts the transport hanger from the plating tank after performing plate processing on the thin processing object, wherein the transport hanger includes an upper gripper that grips an upper part of the thin processing object and a lower gripper that grips a lower part of the thin processing object, and the plating tank includes an upper guide rail that transports the transport hanger in a predetermined moving direction and a member that is provided at a predetermined position of the tank body and that generates an attractive force against the lower gripper of the transport hanger, further wherein a magnetic material is provided within a bottom part of the transport hanger, and the member generates a downward attractive force to stretch the thin processing object, the transport hanger further comprising a plurality of frame-body members interconnecting the upper gripper and the lower gripper each frame-body member having an associated elastic member, wherein the thin processing object is configured to receive a load from the lower gripper through an interaction between the elastic members and the member that generates the downward attractive force, and the lower gripper of the transport hanger moves, from a first position of use further from the member, downward, to a second position of use, toward and closer to the member against the force of the elastic member to place the processing object in the second position of use in a stretched state.
