A structural member in the roof of the main part of a dwelling, placed above the 1-bay wide corridor, *irikawa 入側, between the body of the building and the veranda. Often it is a large curved beam, sloping downward in the same direction as the rafters. The upper end is connected to a strut that is part of the roof framework, koya 小屋, using a tenon, *hozo ほぞ, secured by a plug, hanasen 鼻栓. Occasionally, it receives the cantilever cushion, *hanegimakura 桔木枕, on its lower end to strengthen the roof framework so that it can bear the weight of heavy, thick thatch or tile roofing material. Although all extended beams like cantilevers can be called dashibari, the true cantilever is not normally attached at its upper end and therefore is different from the dashibari.
