摘要： Provided is a power transmission device in which leakage of an electromagnetic wave between a space (1) and a space (2) can be suppressed. The power transmission device includes an electromagnetic wave-shielding wall (10) partitioning the space (1) and the space (2), a rotating shaft (20) penetrating through the electromagnetic wave-shielding wall (10) to transmit rotating drive force, and a bearing (80) supporting the rotating shaft (20). The rotating shaft (20) includes a first shaft member (30) pivotally supported by the bearing (80), a shaft joint part (50) provided on an end (31) of the first shaft member (30), and a second shaft member (40) rotating together with the first shaft member (30). The first shaft member (30) and the second shaft member (40) are formed of a conductive material, and the shaft joint part (50) has an insulating part (51) formed of an insulating material. An outer race component part (16) of the bearing (80) has an annular close-contact surface (18) formed of a conductive material.

摘要： A mechanical seal having a floating sheet which comprises an integrally formed slide ring and a retainer, the slide ring, which is provided with a sliding surface, being insert-molded into one end of the retainer at the time of molding of the latter, the sliding ring being difficult to be machined because of its thereto wear- and corrosion-resistance properties, as well as a method of making such floating sheet. The mechanical seal has a highly airtight sliding surface.
摘要翻译：具有浮动片的机械密封件，其包括一体形成的滑环和保持器，所述滑动环设置有滑动表面，其在成型时嵌入成型在保持器的一端中，滑环由于其耐磨性和耐腐蚀性而难以加工，以及制造这种浮动片的方法。机械密封具有高度气密的滑动表面。
