PROBLEM TO BE SOLVED: To provide a work centering device capable of easily disposing a processing object part of work along a center shaft of a processing portion when processing is performed on a required part of flexible work linearly extending.SOLUTION: A work centering device 1 which guides work to a processing portion having a center axis in a horizontal direction of the processing device to be positioned, has a work supporting portion 100 which can move in parallel with the center axis of the processing portion, and can support the work in parallel with the center axis of the processing portion； and a work guide portion 200 which can move in parallel with the center axis of the work supporting portion. The work guide portion has a work centering portion 210 which is installed so as to project out to the processing device side than the work supporting portion, decreases downward in a vertical direction, and is formed with a recessed portion having a center axis in a horizontal direction on a vertical plane including the center axis of the work supporting portion. The work centering portion matches the center axis of the recessed portion and the center axis of the work in a vertical plane view, while receiving and supporting the work in the recessed portion.SELECTED DRAWING: Figure 1【課題】線状に伸びる可撓性のワークの所望の部位に処理を施す際に、ワークの処理対象部位を処理装置の処理部の中心軸に沿って容易に配置することが可能なワークセンタリング装置を提供すること。【解決手段】ワークを処理装置の水平方向に中心軸を有する処理部に誘導して位置決めするワークセンタリング装置１であって、処理部の中心軸に平行に移動可能で、ワークを処理部の中心軸に平行に支持可能なワーク支持部１００と、ワーク支持部の中心軸に平行に移動可能なワークガイド部２００とを有し、ワークガイド部は、ワーク支持部よりも処理装置側に突出するように設置され、鉛直方向下側に向かって縮小し、ワーク支持部の中心軸を含む鉛直平面上に水平方向の中心軸を有する凹部が形成されたワークセンタリング部２１０を有する。ワークセンタリング部は、ワークを凹部に受け入れて支持しつつ、凹部の中心軸とワークの中心軸とを鉛直方向平面視で一致させる。【選択図】図１
