PURPOSE:To enable assembly operation of this sealing member to be automated for reducing man-hours and production cost by performing thermal fusion of the first sealing member in one piece to a cylindrical part within a mold by mold forming. CONSTITUTION:A hollow cylindrical part 11 is formed at a bracket 8 and an attenuation material 12 is enclosed into it. A first sealing member 14 consisting of a soft thermoplastic elastic body is thermally fused in one piece to an annular stage part 13 which is formed on an inner periphery surface of a cylindrical part 11 by injection molding and a recessed part 15 is provided at a central part of the first sealing member 14 for accepting a protrusion 7 of a reproduction device 1. The other edge part of the cylindrical part 11 is sealed by a second sealing member 16, a mounting part 17 of a second sealing member 16 is pressed into the cylindrical part 11, and an annular protrusion 18 is engaged to an annular groove 19, thus enabling the second sealing member 16 to be sealed to the cylindrical part 11. Therefore, it becomes possible to obtain a vibration-proof device which requires less man-hour for assembling attenuation means and can be produced simply. |
