EDDY CURRENT TYPE DAMPER
An eddy current type damper (1) is provided with: a magnet holding member (2); a first permanent magnet (3) of a thickness (H1); a second permanent magnet (4) of the thickness (H1); a conductive member (5); a ball nut (6); a screw shaft (7); and a copper layer (12) of a thickness (H2). The second permanent magnet (4) is adjacent to the first permanent magnet (3) with a gap therebetween in the circumferential direction of the magnet holding member (2), and has magnetic poles reversely disposed to those of the first permanent magnet (3). The ball nut (6) is disposed inside the magnet holding member (2) and the conductive member (5) and is fixed to the magnet holding member (2) or the conductive member (5). The copper layer (12) is fixed to the conductive member (5) and faces the first permanent magnet (3) and the second permanent magnet (4) with a gap therebetween. The thickness (H1) and the thickness (H2) are set such that 0.018 <= H 1 / R 1 <= 0. 060 or 0.0013 <= H 2 / R 1 <= 0.0065 with respect to a distance (R1) between the center axis of the screw shaft (7) and the center of gravity of the first permanent magnet (3).
涡流式减振器(1)具备磁体保持部件(2)、厚度(H1)的第一永磁体(3)、厚度(H1)的第二永磁体(4)、导电部件(5)、滚珠螺母(6)、丝杠轴(7)、以及厚度(H2)的铜层(12)。第二永磁体(4)在磁体保持部件(2)的圆周方向上与第一永磁体(3)隔开间隙地相邻，磁极的配置与第一永磁体(3)的磁极的配置相反。滚珠螺母(6)配置于磁体保持部件(2)以及导电部件(5)的内部，固定于磁体保持部件(2)或者导电部件(5)。铜层(12)固定于导电部件(5)，与第一永磁体(3)以及第二永磁体(4)隔开间隙地对置。厚度(H1)以及厚度(H2)相对于丝杠轴(7)的中心轴与第一永磁体(3)的重心为止的距离(R1)为0.018≤H1/R1≤0.060，并且0.0013≤H2/R1≤0.0065。
