摘要： A friction stir welding apparatus includes: a rotating shaft, on which a thread for friction stirring is formed; and a drive unit rotatably supporting the rotating shaft. A rotating shoulder configured to rotate together with the rotating shaft to generate frictional heat between the rotating shoulder and back surfaces of workpieces is fixed to a distal end of the rotating shaft. The rotating shoulder is pushed against the back surfaces of the workpieces by a pushing mechanism. A stationary shoulder penetrated by the rotating shaft and configured to hold the workpieces in a sandwiching manner together with the rotating shoulder is non-rotatably mounted to the drive unit or a member connected to the drive unit.

摘要： A railcar includes an underframe and an energy absorber provided at the underframe. The underframe includes a first end beam, a second end beam, and a sliding center sill connecting the first end beam and the second end beam with each other. The sliding center sill includes a first beam member connected to the first end beam, a second beam member connected to the second end beam, and a coupling member coupling the first beam member to the second beam member. The first beam member slides relative to the second beam member when the coupling member breaks by application of an impact load higher than a predetermined load. The sliding center sill and the energy absorber are arranged in a region located between the first end beam and the second end beam.

摘要： A plurality of side modules include a first module, a second module and a third module extending between the first module and the second module in the carbody longitudinal direction and joined to the first module and the second module. A lower end portion of the first module and a lower end portion of the second module oppose and are joined to a floor bodyshell. A lower end portion of a region of the third module opposes the floor bodyshell, the region being located between the first module and the second module. The lower end portion of the region of the third module is freer with respect to the floor bodyshell than the lower end portion of the first module and the lower end portion of the second module. The third module is supported by the floor bodyshell through the first module and the second module.
