In assembling parts, we sometimes have to use large deformation of flexible parts. Buckling deformation of beam has been analyzed mainly for the strength of beam that supports large longitudinal load, but not for the large deflection. We know a rare research for assembling a beam into a hole in a specially deformed beam case, where the beam has small longitudinal load and the deflecting end(DE)lies on the tangent of fixed end of the beam(TFEB). This paper deals with large load acting at the DE and large deformation where the position of DE offsets itself largely from the TFEB and sets itself on shortened position along the TFEB compared with the beam length. Jumping position from a type of beam deformation to another type and the DE traces of those types are clarified and checked experimentally.
