CONSTITUTION:Winding stairs K1 having oblique steps 1 as stairs of a house are arranged, and a notch part 2a is formed in an almost upper half part of a central pillar 2 being the center of a winding part of the oblique steps 1. A handrail A whose installing parts are formed by bending both end parts in the same direction in a longitudinally long shape, is installed/fixed in the vertical direction on/to a vertical side surface of this notch part 2a by fixing bolts.
