When the skeletal structure member receives the load from the outside, the internal pressure of the space in the skeletal member increases. At the same time, a wedge-shaped member widens the space by expanding the skeletal member while advancing into the space, and the internal pressure of the space decreases, and excessive pressure is prevented from increasing. Therefore, the internal pressure of the space can be kept approximately constant, and thus, local deformation such as the bend of the member does not occur, and a load which can be supported by the skeletal structure member does not decrease, and a larger load can be supported. Such action continues until the skeletal structure member is crushed, and the skeletal structure member can be deformed to a larger displacement amount while supporting a larger load, and therefore, the absorbed energy amount of the skeletal structure member can be increased.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
