PURPOSE:To ensure the caulking of an end cap by mounting the end cap on the opening section of a cylindrical member, and caulking a taper section connected to an end cap mounting step section and expanded in diameter toward the opening end toward the caulking face of the end cap. CONSTITUTION:The opening section 21 of a cylindrical member 20 is provided with an end cap mounting step section 27 formed on the inner wall face 25 of the cylindrical member 20 toward the outer wall face 26 of the cylindrical member 20 and having a nearly L-shaped cross section and a taper section 29 connected to it and expanded in diameter toward an opening end 28. An end cap 32 is provided with a wall face 35 vertically erected from the edge section 34 of a bottom face 33 and a caulking face 37 formed into a circular arc shape toward the center section from the periphery section of the wall face 35. When the opening section 21 is caulked after the end cap 32 is mounted on the end cap mounting step section 27 of the opening section 21, the taper section 29 starts to be bent from a boundary section 29a, and the taper section 29 is bent along the caulking face 37 of the end cap 32 while the material flows toward the opening end 28.
