摘要：
A heat exchanger tube vibration suppression device and a steam generator are provided. The heat exchanger tube vibration suppression device includes: a plurality of sleeves (101) disposed in a heat exchanger tube (66) with a predetermined gap in relation to an inner surface of the heat exchanger tube (66) so as to extend in a longitudinal direction of the heat exchanger tube; and a connecting member (102) that connects the plurality of sleeves (101) so as to be movable between a contracted position at which adjacent sleeves (101) overlap at least partially and an extended position at which the amount of overlap of the adjacent sleeves (101) is minimized. In this way, it is possible to suppress the vibration of the heat exchanger tube appropriately.
