To provide a front axle beam which can improve flexural rigidity in a vehicle length direction while ensuring flexural rigidity in a vehicle height direction.SOLUTION: A front axle beam 1 comprises two king pin attachment parts 2, two spring attachment seat parts 3, a beam part 4, and two arm parts 5. The spring attachment seat part 3 is located between the king pin attachment parts 2. The beam part 4 connects the spring attachment seat parts 3. The arm part 5 connects the king pin attachment part 2 and the spring attachment seat part 3. The arm part 5 has an I-shaped cross section. The beam part 4 has an H-shaped cross section. The spring attachment seat part 3 includes a shank 32. The shank 32 has an O-shaped cross section twisted around an axis.SELECTED DRAWING: Figure 1

    【課題】車高方向の曲げ剛性を確保しつつ、車長方向の曲げ剛性を高めることができるフロントアクスルビームを提供する。【解決手段】フロントアクスルビーム1は、2つのキングピン取付け部2と、2つのバネ取付け座部3と、ビーム部4と、2つのアーム部5と、を備える。バネ取付け座部3は、キングピン取付け部2同士の間に配置される。ビーム部4は、バネ取付け座部3同士をつなぐ。アーム部5は、キングピン取付け部2とバネ取付け座部3とをつなぐ。アーム部5はI字形の横断面を有する。ビーム部4はH字形の横断面を有する。バネ取付け座部3は軸部32を含む。軸部32は、軸回りに捩じられたO字形の横断面を有する。【選択図】図1
