Rare technical term for the peg fitted into the cavity of an oar, used in a traditional Japanese oarlock (see 櫓杭).
See also: 櫓杭
The fulcrum peg is an important part that supports the oar of a traditional Japanese boat.
Rare technical term; the kanji 櫓 (oar) and 臍 (navel) are used descriptively.
Variant using 艪 (oar) instead of 櫓; equally rare.
Compound of 櫓 (ro, 'oar') and 臍 (heso, 'navel'), referring to the peg's navel-like shape and function. The exact historical derivation is uncertain.
