To provide a spacer capable of preventing arrangement displacement of a reinforced cage with respect to a drilled hole.SOLUTION: A spacer 1 is attached to a reinforced cage 20 built into a drilled hole 30. The spacer 1 includes a protruding portion 11 extending from the reinforced cage 20 toward an outside in a radial direction. In a process in which the reinforced cage 20 is built into the drilled hole 30 while making a tip portion of the protrusion 11 be in contact with a hole wall 31 of the drilled hole 30, a posture of the protrusion 11 is changed by an elastic force so as to change a radial dimension according to a distance between the reinforced cage 20 and the hole wall 31.SELECTED DRAWING: Figure 3
【課題】掘削孔に対する鉄筋籠の配置ずれを抑制することができるスペーサを提供する。【解決手段】スペーサ１は、掘削孔３０に建込む鉄筋籠２０に取り付けられる。スペーサ１は、鉄筋籠２０から径方向の外側に向かって延設された突出部１１を有し、突出部１１の先端部を掘削孔３０の孔壁３１に接触させながら鉄筋籠２０を掘削孔３０に建込む過程において、突出部１１は鉄筋籠２０と孔壁３１との間の距離に応じて径方向の寸法を変化させるように弾性力をもって姿勢変更される。【選択図】図３
