PROBLEM TO BE SOLVED: To provide a recliner seat for a vehicle which allows a backrest of a vehicle seat to be rotated and fixed at predetermined angles.SOLUTION: A recliner shaft 100 for a vehicle includes: a hollow pipe shaped body 200; a plurality of spline projections 300 formed to project radially outward on an outer peripheral surface of the body, and extending along a long direction of the body; and a plurality of groove parts 400 formed to be recessed outward radially corresponding to each spline projection on an inner peripheral surface of the body. The plurality of the spline projections are spaced apart by α angle along a circumferential direction of the body, any one pair of adjacent spline projections among the plurality of the spline projections are spaced apart by β angle larger than the α angle, and a protrusion 500 having a width larger tan the spline projections are formed between the pair of the spline projections.SELECTED DRAWING: Figure 1

    【課題】車両シートの背もたれを一定の角度で回転及び固定できるようにする車両シート用リクライナーシャフトに関する。【解決手段】車両シート用リクライナーシャフト100は、中空パイプ形状の本体200と、本体の外周面で半径方向外側に突出形成され、本体の長さ方向に沿って延長される複数のスプライン突起300と、本体の内周面でスプライン突起にそれぞれ対応して半径方向外側に陥没形成される複数の溝部400を含み、複数のスプライン突起は本体の円周方向に沿ってα角度間隔で離隔し、複数のスプライン突起のうち隣接する何れか一対のスプライン突起はα角度よりさらに大きいβ角度間隔で離隔し、一対のスプライン突起の間には一対のスプライン突起の間にはスプライン突起よりさらに大きい幅を有する突出部500が形成される。【選択図】図1
