PROBLEM TO BE SOLVED: To provide a displacement measuring device the structure of which is simple and compact, the installation location of which is not limited and which is capable of highly accurately measuring an interlayer displacement of a structure without being applied with an unreasonable force even when a large deformation is generated in the out-of-plane direction.SOLUTION: A diagonal member 2 constituting a displacement measuring device 1 is attached with a linear shaft 6 via a linear bush 5 at one end of a main body cylinder part 21, and the liner shaft 6 is constituted in such a manner that a part thereof slides on the same axial line as the main body cylindrical part 21, while being taking out and inserting into the inside of the main body cylindrical part 21. Both end parts of the diagonal member 2 are connected to a lower floor (foundation 91) and an upper floor (floor beam 92) via a ring ball 4 capable of being bent in an arbitrary direction. The expansion/contraction displacement of the diagonal member 2 can be obtained by measuring an axial direction displacement between the main body cylindrical part 21 and a measurement point provided on the other of the linear shaft 6 by a displacement meter 3 added to one of the main body cylindrical part 21 and the linear shaft 6 in the vicinity of the linear bush 5.SELECTED DRAWING: Figure 1 |
