Patent number: 9623882Abstract: 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.Type: GrantFiled: September 4, 2013Date of Patent: April 18, 2017Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Kei Uchida, Seiichiro Yagi, Eiichi Kato, Chihiro Okayama, Toshiyuki Hirashima, Akihiro Tada

Patent number: 9315199Abstract: A driver's cab of a railcar includes: side bodyshells; a roof bodyshell; and an interior panel unit including a pair of side panels located at an inner side of the side bodyshells, a ceiling panel located at an inner side of the roof bodyshell, and a back-surface panel that separates the driver's cab from a passenger room. At least one of the panels includes an opening portion through which an adjusting member can be inserted, the adjusting member being configured to adjust positions of the one panel and the side bodyshell or positions of the one panel and the roof bodyshell. An interior space of the driver's cab is defined by coupling the adjacent panels to one another. The adjusting member adjusts a position of the driver's cab relative to the side bodyshell or the roof bodyshell.Type: GrantFiled: March 26, 2013Date of Patent: April 19, 2016Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Mitsuhiro Matsumoto, Chihiro Okayama
