PROBLEM TO BE SOLVED: To provide a vacuum pressing-force multipoint contact piece and a metallic spring pressure generation method, the vacuum pressing-force multipoint contact piece capable of reducing heat generation and operation force by disposing many movable contact parts between a pair of solid contact piece and a movable contact piece in a vacuum container so as to divert an electric current, and the metallic spring pressure generation method capable of generating a spring pressure for the vacuum pressing-force multipoint contact piece in the vacuum container.SOLUTION: A plurality of solid contact pieces 5 having a gap is disposed so as to be movable individually by spring pressing-force. Thus, a multipoint contact is achieved between the plurality of solid contact pieces 5 and movable contact pieces 6 to divert an electric current for reducing heat and operating force. After completion of high-temperature work in vacuum container manufacturing, a loss of spring-force due to high-temperature deformation of parts and a vacuum high-temperature adhesion between parts during vacuum container manufacturing can be avoided by a method in which an external projection 22 of a supporting pin housing a spring is put in a supporting plate hole so as to allow the spring to produce a spring force required. The spring pressing-force produced by the work following to the completion of the high-temperature work can maintain the functions of the plurality of solid contact pieces 5. |
