<P>PROBLEM TO BE SOLVED: To provide a fuel exchanging machine for improving aseismatic performance. <P>SOLUTION: This fuel exchanging machine 1 includes: a rail 10 for a bridge installed on a floor 3 in the periphery of a nuclear reactor pool 2 in which a fuel bar for nuclear reactor is housed; and a bridge 20 having a bridge wheel 21 which travels on the rail 10 for a bridge and a bridge leg part 22 by which the bridge wheel 21 is held so as to freely rotate. A guide member 70 extended along the longitudinal direction of the rail 10 for a bridge is installed at the side part of the bridge leg part 22, and a force absorbing mechanism 80 is interposed between the bridge leg part 22 and the guide member 70. The force absorbing mechanism 80 includes: an abutting member 82 configured so as to freely abut to the guide member 70; a force absorbing part 84 configured to absorb a force in a direction orthogonal to the longitudinal direction of the rail 10 for a bridge; and an abutting member guide part 90 configured to regulate the longitudinal displacement of the rail 10 for a bridge to the bridge leg part 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
