To provide a handrail bracket of a system for supporting the butt end position of a handrail bar without causing the wobble of the handrail bar due to the deterioration of the effect of a screw during use.SOLUTION: In a handrail bracket for supporting the butt end position of a handrail bar P by fixing the handrail bar P to a mounting face plate part 11b of the handrail bracket with a screw 3 screwed into the center from the butt end side of the handrail bar P, a seat surface 31a of a head part 31 of the screw 3 is formed into a conical shape, and a seat surface 11c of the mounting surface plate part 11b on which the seat surface 31a of the screw 3 sits is formed in a concave shape of a conical surface, and a top angle θ1 of the seat surface 11c is formed to be 5 to 20 degrees larger than a top angle θ3 of the seat surface 31a of the screw 3.SELECTED DRAWING: Figure 3
【課題】使用しているうちにネジの効きが悪くなって手摺り棒がぐらつくことのない手摺り棒の木口位置を支持する方式の手摺りブラケットを提供すること。【解決手段】手摺りブラケットの取付面板部１１ｂに、手摺り棒Ｐを、手摺り棒Ｐの木口側からその中心に螺入するネジ３で固定して手摺り棒Ｐの木口位置を支持する手摺りブラケットにおいて、ネジ３の頭部３１の座面３１ａを円錐形状に形成し、ネジ３の座面３１ａが着座する取付面板部１１ｂの着座面１１ｃを円錐面の凹み形状に形成し、かつ、着座面１１ｃの頂角θ１を、ネジ３の座面３１ａの頂角θ３より、５°～２０°大きく形成する。【選択図】図３
