PROBLEM TO BE SOLVED: To provide a protective fence column capable of exhibiting an improvement in bearing power, by restraining rupture of a welding part of a column body and a baseplate.SOLUTION: A protective fence column 1 comprises a baseplate 2 fixed to a foundation and a closed cross-sectional hollow-shaped column body 3 erected and joined on the baseplate 2. The baseplate 2 is fixed to the foundation by a fixing member Bo with a line direction Ld of a road as a width direction W, and assuming a substantially orthogonal line to the line direction of the road by passing through a central part Wo in the width direction W in the baseplate 2 as a virtual bending line Li2, the fixing member Bo is arranged in a bending restraining position SP for restraining bending with the virtual bending line Li2 as the axis in the baseplate 2 when the column body 3 receives a load via a cross beam member B. 【課題】支柱本体とベースプレートとの溶接部分の破断を抑制し、支持力の向上を発揮することができる防護柵支柱を提供する。【解決手段】基礎に固定されるベースプレート２と、ベースプレート２上に立設して接合された閉断面中空状の支柱本体３と、を備える防護柵支柱１であって、ベースプレート２は、道路の車線方向Ｌｄを幅方向Ｗとして固定部材Ｂｏによって基礎に固定されており、ベースプレート２における幅方向Ｗの中央部Ｗｏを通過し道路の車線方向に略直交する線を仮想折曲線Ｌｉ２とした場合、固定部材Ｂｏは、横梁部材Ｂを介して支柱本体３が荷重を受けた際のベースプレートに２おける仮想折曲線Ｌｉ２を軸とする折曲を抑制する折曲抑制位置ＳＰに配置されている。【選択図】図６
