ROD-SHAPED BODY AND CYLINDRICAL BODY
To provide means for carrying out connection between rod-shaped bodies with a less workload by a simple structure.SOLUTION: A rod-shaped body has a diameter-reducing face constituted by that a radius from an axis is progressively reduced, a diameter-increasing face constituted by outer circumferences of protruded parts with a relatively large diameter and aligned in an axis direction, and a recessed diameter face constituted by a bottom face of recessed parts recessedly provided alternately with the protruded part in the axis direction. Relative to the diameter-reducing face, the diameter-increasing face and the recessed diameter face are connected along a circumferential direction. The protruded part is constituted by having a width-reducing part continuously or intermittently extending in approximately arcuate shape toward a circumferential direction and having a width reducing from a side of the diameter-increasing face toward the diameter-reducing face.SELECTED DRAWING: Figure 1
【課題】簡易な構造によって、少ない作業負担で棒状体同士の連結を行うための手段を提供する。【解決手段】軸からの半径が漸次縮径して成る縮径面と、比較的大径で軸方向に列設される凸部の外周が成す拡径面と、軸方向に向かって上記凸部に交番して凹設される凹部の底面が成す凹径面と、を有する棒状体であって、上記縮径面に対し、周方向に沿って上記拡径面と上記凹径面が連設され、上記凸部は、周方向に向かって連続的又は断続的に略弧状に延在し、上記拡径面側から上記縮径面側に向かって縮幅する縮幅部を有して構成される。【選択図】図１
