To provide a leaf suspension device capable of improving durability furthermore than hitherto without worsening riding comfort.SOLUTION: A leaf suspension device formed by laminating a plurality of leaf springs 2A, 2B, and by fixing mutually respective intermediate parts in a longer direction, has a constitution in which, concerning a leaf spring 2A on the first stage from above, a plate thickness of a more front part than the intermediate part is relatively increased to a rear part so as to be formed front-and-rear asymmetrically, and concerning a leaf spring 2B on the second stage, a plate thickness of a more rear part than the intermediate part is relatively reduced to the front part so that front-and-rear spring constants of the whole leaf springs 2A, 2B become equal.SELECTED DRAWING: Figure 1

    【課題】乗り心地の悪化を招くことなく耐久性を従来より向上し得るリーフサスペンション装置を提供する。【解決手段】複数枚のリーフスプリング2A,2Bを積層し且つ夫々の長手方向の中間部を相互に固定したリーフサスペンション装置に関し、上から一段目のリーフスプリング2Aについて中間部より前方部分の板厚を後方部分に対し相対的に増やして前後非対称に形成し、二段目のリーフスプリング2Bについては中間部より後方部分の板厚を前方部分に対し相対的に減らしてリーフスプリング2A,2B全体の前後のバネ定数が同等となるように構成する。【選択図】図1
