<p>PURPOSE: To perform a proper conductivity treatment even in an L-type insulation cylinder by providing protrusions at least at two locations on the outer periphery of an external conductive layer via an injection port and covering a conductive rubber sheet with a hole engaged to the protrusions over the injection port of the external conductive layer. CONSTITUTION: Protrusions 10, (10) are formed at two locations on opposing side surfaces via an injection port 5 of an insulation material on the outer periphery of an external conductive layer 3 and at the same time each one hole 12 is formed at both edge sides of a conductive rubber sheet 11 which is formed while it is curved. Then, the conductive rubber sheet 11 may be covered on an L-type insulation cylinder externally and the holes 12, 12 of the sheet are engaged to the protrusions 10, (10) of the external conductive layer, thus depositing the conductive rubber sheet 11 to the outer periphery of the external conductive layer 3, enabling the conductive rubber sheet 11 and the external conductive layer 3 to obtain an electric continuity, and covering the outer periphery including the injection port 5 for proper conductive treatment.</p> |
