PROBLEM TO BE SOLVED: To provide a space stabilizing device which uses a shim or a wave washer made of shape memory alloy between a rotatable shaft supporting loads and a bearing, and enabling to stably operate corresponding to temperature changes. SOLUTION: The space stabilizing device comprises the first shaft (9) having a load (8) between a pair of bearings (4, 5) of a U-shaped supporter (1), and circular shims or wave washers (13, 14) made of shape memory alloy provided between step parts (11, 12) at the both side of the first shaft (9) and the bearings (4, 5). The device stably operates by applying adequate preload to each of the bearings (4, 5) when temperature changes. COPYRIGHT: (C)2005,JPO&NCIPI
