<p>PURPOSE:To surely obtain electrical conduction of a guide member further to swivel the guide member accurately further stably, by forming one part of a supporting member, which comes into contact with a metallic part of the guide member, from metal. CONSTITUTION:A guide member 2 is rotatably provided for a pin 3 with a supporting point A serving as the center. The pin 3 is obtained by injection molding by integrally forming a pin main unit 3a, consisting of plastic material, with a cylindrical pipe 3b made of brass. Conduction between the pin main unit 3a and the cylindrical pipe 3b is ensured because they are integrally molded. A device, stopping the pin main unit 3a by a machine screw 11 to a device main unit side plate 7, ensures conduction between these pin main unit 3a and device main unit side plate 7. While conduction between the cylindrical pipe 3b and a bottom side guide plate 2b is ensured because they are formed by fellow metals. Accordingly, a necessary electric characteristic can be realized for the guide member 2 because the conduction is surely obtained between the device main unit side plate 7 and the guide member 2 through the pin 3.</p> |
