To disclose a seat angle adjuster and a ratchet wheel for the seat angle adjuster.SOLUTION: The present invention discloses a ratchet wheel (3) for a seat angle adjuster. The ratchet wheel (3) comprises a base plate (A) having a pressed groove (a), and a peripheral wall of the pressed groove (a) is provided with ratchet teeth (3a) of the ratchet wheel whose depth is greater than thickness of the base plate (A). The present invention further provides a seat angle adjuster. The ratchet wheel (3) of the present invention is press-formed from the base plate (A), the ratchet teeth (3a) of the ratchet wheel is arranged so that depth thereof is larger than the thickness of the base plate (A). The thickness of the base plate (A) is thinner and weight of the base plate (A) is lighter, compared with the prior art, so that weight and thickness of the seat angle adjuster are reduced, and the requirement for light weight is met.SELECTED DRAWING: Figure 1

    【課題】本発明は、シート角度調整器及びこのシート角度調整器のための爪車を開示する。【解決手段】本発明は、シート角度調整器のための爪車(3)を開示し、爪車(3)は、プレス溝(a)を有するベースプレート(A)を含み、プレス溝(a)の周壁には、深さがベースプレート(A)の厚さより大きい爪車ラチェット歯(3a)が設けられている。本発明は、シート角度調整器をさらに提供する。本発明の爪車(3)は、ベースプレート(A)からプレス成形され、爪車ラチェット歯(3a)の深さは、ベースプレート(A)の厚さより大きくするように配置され、従来の技術に比べると、ベースプレート(A)の厚さは薄くなり、重量は軽くなり、シート角度調整器の重量及び厚さを低減させ、軽量化の要求を満たす。【選択図】図1
