To position a sliding member in a boom without welding a regulation member for positioning the sliding member to the boom.SOLUTION: A positioning structure of a connection slide plate body 30 comprises: the connection slide plate body 30 which is disposed in the inner surface 11a of the tip of a base end boom 11 (outer boom) constituting a telescopic boom 10; and tip plates 51, 52 which are fixed to the surface of a flange 11d of the base end boom 11. Engaging hole 39a are formed in the lower surface 30b of the tip plate body 30 facing the inner surface 11a, teeth 51a, 52a (projected shapes) are formed in the inner edges of the tip plates 51, 52 so as to fit in the engaging holes 39a, and the teeth 51a, 52a fit in the engaging holes 39a to position the connection slide plate body 30 at the prescribed position of the base end boom 11.SELECTED DRAWING: Figure 3
【課題】スライド部材を位置決めするための規制部材をブームに溶接することなく、スライド部材をブームに位置決めする。【解決手段】連結スライドプレート体30の位置決め構造は、伸縮ブーム10を構成する基端ブーム11(外側ブーム)の先端部の内面11aに配置された連結スライドプレート体30と、基端ブーム11のフランジ部11dの面に固定された先端プレート51,52と、を備え、連結スライドプレート体30の、内面11aに向いた下面30bに、係合孔39aが形成され、先端プレート51,52の内縁に、係合孔39aに嵌め合わされる歯51a,52a(凸形状)が形成され、係合孔39aに歯51a,52aが嵌め合わされて、連結スライドプレート体30を基端ブーム11の所定位置に位置決めする。【選択図】図3
