PURPOSE:To prevent a vibration absorbing device from being damaged due to shocks arising during transport of operation by a constitution wherein a weight rod with a weight fixed at its one end is arranged on the outer wall of a closed vessel and yet the excessive displacement of said weight with respect to said vessel is rendered to be limited. CONSTITUTION:The weight rod 12, at one end of which the weight 15 is fixed, is fitted to a nut 11 fixed by welding on the outer wall of the closed vessel 1. In addition, a displacement limiting piece 16 so constituted as to have a small gap 14 with respect to the weight 15 is fitted to the weight rod 12. Due to the constitution as mentioned above, even when the long weight rod 12 of the vibration absorbing device 17, the excessive displacement due to shocks arising during transport or operation is limited, resulting in preventing the vibration absorbing device 17 from being damaged and deformed. |
