Zusammenfassung:	To provide a suspension arm that can improve hot water circulation.SOLUTION: A suspension arm 1 formed by casting, comprising a strike plate 2 that receives a load of a spring C1, and a cylindrical part 3 protruding from the strike plate 2, has a configuration in which a volume of a first part 3a is larger than a volume of a second part 3b and/or a height of the first part 3a is larger than a height of the second part 3b, when an upstream side in a direction of hot water flow during casting is the first part 3a in the cylindrical part 3 and a downstream side is the second part 3b in the cylindrical part 3.SELECTED DRAWING: Figure 1 【課題】湯回り性を改善できるサスペンションアームを提供することを目的とする。【解決手段】サスペンションアーム１は、スプリングＣ１の荷重を受ける受座２と、受座２から突出する円筒部３を備え、鋳造により成形されるサスペンションアームであって、鋳造する際の湯流れ方向の上流側を円筒部３における第１部位３ａとし下流側を円筒部３における第２部位３ｂとしたとき、第１部位３ａの体積を第２部位３ｂの体積よりも大きく形成した構成、および／または、第１部位３ａの高さを第２部位３ｂの高さよりも大きく形成した構成である。【選択図】図１
