PROBLEM TO BE SOLVED: To easily attach a mark to the center of one side surface of a three-dimensional shape such as a column, a building material, a gravestone and a signboard even by a nonexpert.SOLUTION: A centering tool is composed of a long size-shaped plate body having an index in the center, a pair of left-right folding-back members provided in left-right end parts of this long size-shaped plate body, a pair of left-right operation pieces positioned on the inside of the left-right folding-back members, slidably provided in the long size-shaped plate body and having a pair of left-right abutting parts for contacting so as to sandwich both side surfaces of a centering object and a pair of traction members for respectively connecting one end part to the left operation piece and the other end part to the right operation piece and respectively folded back in the left-right folding-back members in a substantially stretched state, and when manually sliding any one of at least the left-right operation pieces to the long size-shaped plate body, the left-right operation pieces mutually synchronously approach or separate with the index as a reference.SELECTED DRAWING: Figure 1
【課題】熟練者でなくても、容易に柱、建材、墓石、看板等の立体的形状の一側表面の中心に印を付することができること。【解決手段】中心に指標を有する長尺状板体と、この長尺状板体の左右端部に設けられた左右一対の折り返し部材と、前記左右の折り返し部材の内側に位置しかつ長尺状板体にスライド自在に設けられ、かつ芯出し対象物の両側面を挟むように接触する左右一対の当接部分を有する左右一対の操作片と、左の操作片に一端部が、一方、右の操作片に他端部がそれぞれ連結されると共に、略張った状態で左右の折り返し部材にそれぞれ折り返された一対の牽引部材とから成り、少なくとも左右の操作片のいずれか一方を手動で長尺状板体にスライドさせると、該左右の操作片は指標を基準にして互いに同期的に接近又は離反する芯出し工具。【選択図】図１
