To provide a preceding handrail that facilitates mounting work to a connection receiving part at a high position of a support regardless of the right and left order of a connection member to be mounted.SOLUTION: A preceding handrail 20 has connection receiving parts provided at predetermined intervals along the axial direction, and a horizontal member 21 to be erected in the substantially horizontal direction and a diagonal member 51A to be erected in the oblique direction are connected through a first connection member 30A provided with an insertion part 43 to be inserted into the connection receiving parts from above. A first connecting member 30A is provided with a horizontal member mounting part 34 rotatably mounted in the vicinity of the end part of the horizontal member 21, and a diagonal member mounting part 37 rotatably mounted with the diagonal member 51; the horizontal member mounting part 34 abuts on the horizontal member 21 and is provided with a holding protrusion 34c for holding the insertion member 43 in a substantially right angle direction, and the diagonal member mounting part 37 is provided with a rotation preventing protrusion 37c to abut on the diagonal member 51A.SELECTED DRAWING: Figure 3
【課題】 取り付ける連結部材の左右の順序に関係なく、支柱の高い位置にある連結受部への取り付け作業を容易にする先行手摺りを提供する。【解決手段】 軸方向に沿って所定間隔に設けられた連結受部を有し、所定間隔で立設された支柱の間に、略水平方向に架設される水平部材２１と斜め方向に架設される斜材５１Ａとが、前記連結受部に上方から差し込まれる差込部４３を備えた第１連結部材３０Ａを介して連結された先行手摺り２０である。第１連結部材３０Ａは、水平部材２１の端部近傍と回動可能に取り付けられる水平部材取付部３４と、斜材５１を回動可能に取り付ける斜材取付部３７とを備え、水平部材取付部３４は、水平部材２１と当接し、差込部材４３が略直角方向に保持するための保持用突出部３４ｃが設けられ、斜材取付部３７は、斜材５１Ａと当接する回転防止突部３７ｄが設けられる。【選択図】 図３
