HANDRAIL BAR AND MANUFACTURING METHOD OF HANDRAIL BAR
To provide a handrail bar capable of improving workability during manufacture, and a manufacturing method of the handrail bar with improved workability during manufacture.SOLUTION: A handrail bar 1A comprises an elongate substrate 2 and a surface layer sheet 5. The substrate 2 comprises a first recess part 3 and a second recess part 4. In an axial direct cross-sectional view, an angle α2 of a side surface 4a of the second recess part 4 relative to an outer peripheral surface 2f of the substrate 2 is greater than an angle α1 of a side surface 3a of the first recess part 3 relative to the outer peripheral surface 2f of the substrate 2. The surface layer sheet 5 is disposed on the substrate 2 so that an end edge part 5e of the surface layer sheet 5 reaches at least the side surface 3a of the first recess part 3.SELECTED DRAWING: Figure 1A
【課題】製造時の作業性が改善できる手摺棒と、製造時の作業性が改善された手摺棒の製造方法と、を提供する。【解決手段】手摺棒1Aは、長尺状の基材2と、表層シート5と、を備えている。基材2は、第一凹部3と、第二凹部4と、を備えている。軸直断面視において、基材2の外周面2fに対する、第二凹部4の側面4aの角度α2は、基材2の外周面2fに対する、第一凹部3の側面3aの角度α1よりも大きい。表層シート5は、当該表層シート5の端縁部5eが、少なくとも第一凹部3の側面3aに達するように、基材2に配置されている。【選択図】図１Ａ
