とを特徴とするテレスコピツクカバー構造。 The size of the cover body is changed stepwise from the largest cover body to the smallest cover body, so that each cover body is housed in an adjacent large cover body, and a sliding protrusion is provided at the tip of the cover body. , in a telescopic cover structure in which a protrusion is formed at the base end to engage with a sliding protrusion of an adjacent cover body, a through hole is formed at the same position of the cover body and the sliding protrusion; Countersinking is performed on one side of each through-hole, and the sliding protrusion and the cover body are joined to each other at the non-spotted surfaces to form the sliding protrusion and the cover body. A caulking pin having a head portion corresponding to the above-mentioned counterbore shape and an effective axial length slightly longer than the combined thickness of the sliding protrusion and the cover body is inserted into the through hole, and a caulking pin is inserted from above and below the caulking pin. A telescopic cover structure characterized in that the sliding protrusion and the cover body are fixed by welding.
