noboribari 登梁

Lit. "rising beam," "raking beam."

1　Also *noboriki 登木 or *nobori 登. Transverse beams in a timber-framed roof, set at a pitch instead of horizontally. An economy measure, used to achieve sufficient headroom for lofts and attics (*zushi 辻子, *tsushi nikai 厨子二階) in the roof-space, while keeping the level of the eaves *noki 軒 relatively low, noboribari usually spanned from the purlin *keta 桁 to the beam beneath the ridge pole *jimune 地棟. Associated with shallowly-pitched tiled or shingle roofs, rather than thatch, the slope of noboribari varied, but was usually less steep than the pitch of the roof. The end might project beyond the plane of the wall on the outside to support a round eaves purlin *dashigeta 出桁. Much used and perhaps pioneered in town houses *machiya 町家, noboribari later came to be used in shingled farmhouses, especially those involved with sericulture. Also found in outhouses and storehouses *dozō 土蔵.

2　Alternative term for *hiuchibari 火打梁.
