Structural characteristics of the tightening point between railway car body and interior equipments conposed of a tightening bolt and an attachment rail made with aluminium hollow extrusion is studied. To investigate the structural characteristics of the attachment rail and dispersion of axial force on the tightening bolt must be separately considered. Scatter of the structural characteristics of the attachment rall accompanied with load relies on constrained force of the tightening bolt is carried out. Dispersion of residual stress of the attachment rail which is caused by bolt tightening shows the same load-stress relationship in high load region an no-fixed model. The FEM calculation with fixed and free model of the tightening bolt is in good agreement with the load test result.
