    摘要： A method of manufacturing a thrust plate for a dynamic pressure bearing in which the upper and lower end surfaces thereof have a highly precise perpendicular angle relative to the central axis thereof. The thrust plate has an annular shape, and a central hole is formed therein in which is fitted a shaft body. Thrust surfaces that form a portion of thrust bearing units are formed at both end surfaces of the thrust plate. The method of manufacturing the thrust plate includes a blanking step in which a plate-like work piece is press-cut to obtain an annular blank intermediate, an end surface polishing step in which both end surfaces of the blank intermediate are polished, and a shaving step in which an inner hole and an outer periphery of the polished blank intermediate are simultaneously press-cut to shave off surfaces thereof.

    摘要： It is an objective of the present invention to provide a battery case lid and a manufacturing method for the battery case lid which inhibit work hardening of a metal plate workpiece and which facilitate manufacture of a battery case lid. Provided is a battery case lid (1) formed by working a metal plate, including: a substrate section (2) and an explosion-proof valve (4) formed in the substrate section (2), wherein the explosion-proof valve (4) has a reduced thickness section (41) thinner than the substrate section (2), and the reduced thickness section (41) is formed by extending the metal plate by applying pressure while the metal plate is kept unrestrained.
