PURPOSE:To provide a jig device which prevents sticking of a plating soln. on the shaft of a cylinder by tightening double cylindrical bodies to be fitted to the shaft of the cylinder by means of a chuck consisting of a wedge body and a tapered body, fixing a covering cylinder to an outside cylinder, and installing immovably the same to the cylinder. CONSTITUTION:Double cylindrical bodies 4, 5 of a jig 1 are fitted to a shaft B of a cylinder A in a plating device for a cylinder. When the screw parts 2, 3 of the bodies 4, 5 are turned, the inside body 4 is tightened to the outside circumference of a shaft 1 by means of a chuck 6 constituted of a wedge body 6a and a tapered body 6b, by which the outside cylindrical body 5 is fixed immovably to the body 4. A covering cylinder 7 is then screwed forward over the body 5 and the end 8 of the cylinder 7 is fitted tightly to the shaft part B of the cylinder A, then the end of the cylinder A and the shaft B are covered with the bodies 4, 5 and the cylinder 7. If the cylinder A is installed freely rotatably on the plating device by using such jig 1, the generation of an inconvenience such as sticking of the plating soln. on the shaft B is obviated. |
