<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a base isolation plug capable of enhancing damping performance and displacement followability of a base isolation device, without using lead as a material, and a device for manufacturing the base isolation plug capable of carrying out the manufacturing method. <P>SOLUTION: In this manufacturing method, a powder material 2 is press-molded into a shape recessed in the central part, compared with the peripheral part thereof, when molding the base isolation plug 6 for the base isolation device 8, by press-molding the powder material 2 filled in a molding die 3, and then press-molds a pressure reception face 7 of the press-molded powder material 2 into a planar shape orthogonal to a pressing direction. The base isolation plug 6 is manufactured using the manufacturing method. The manufacturing device is provided with the molding die 3 and a stamper 5 for carrying out the manufacturing method. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
