Interior equipment installation structure for railcar
In the interior equipment installation structure for a railcar according to the present invention, a first installation member is mounted to a roof body shell along the car longitudinal direction or the car width direction. Second installation members are attached to the first installation member using mechanical fastening tools such as bolts with the positions of the second installation members adjusted in the up-down direction of the car. The second installation members are used for installing lighting appliances such as fluorescent lights, each has a size corresponding to each of the lighting appliances, and are continuously installed. There are portions in which plate members are overlapped with each other between respective adjacent ones of the second installation members, and hand strap receivers are installed in these portions.

one of the inner members has inner member bent portions, the inner member bent portions being bent upward and extending in the longitudinal direction of the second installation members, at one side thereof,
a gap is formed between each of the inner member bent portions and the extending portion, and
each of the bent insertion portions formed on one of adjacent ones of the second installation members is inserted into the gap formed at the other one of the second installation members and connected thereto.
6. The interior equipment installation structure for a railcar according to claim 3 , further comprising inner members to be attached to the respective short side ends of each of the second installation members, wherein
each of the second installation members has bent insertion portions, the bent insertion portion being bent upward and extending in the longitudinal direction of the second installation members, at one of short side ends of the horizontal portion, and an extending portion extending in the longitudinal direction of the second installation members at the other short side end thereof,
one of the inner members has inner member bent portions, the inner member bent portions being bent upward and extending in the longitudinal direction of the second installation members, at one side thereof,
a gap is formed between each of the inner member bent portions and the extending portion, and
each of the bent insertion portions formed on one of adjacent ones of the second installation members is inserted into the gap formed at the other one of the second installation members and connected thereto.
7. The interior equipment installation structure for a railcar according to claim 6 , wherein each of the inner member bent portions has a distal end being inclined so as to guide the insertion of a corresponding one of the bent insertion portions.
