LONG-SIZED MEMBER AND MANUFACTURING METHOD OF THE SAME

Japanese Patent JP2018002016

A

PROBLEM TO BE SOLVED: To provide a long-size member which allows an opening width of a clamping part to be partially differentiated without requiring to partially differentiate an angle formed by a lateral wall and a bottom wall, and to provide a manufacturing method of the long-size member.SOLUTION: A long-size member is arranged in order to perform sealing to an opening part periphery of a vehicle body. A clamping part 10a constituted with a bottom wall 11, a first lateral wall 12 and a second lateral wall 13 is provided and a seal part 17 is provided on an outer surface of the first lateral wall 12. A width direction development size of the clamping part 10a is constant over the whole of longitudinal direction, however, a width size of the bottom wall 11 is partially different in the longitudinal direction. The long-size member is continuously processed successively in the longitudinal direction according to an extrusion molding. A manufacturing process of the long-size member includes a preliminary molding process and a width varying process of the bottom wall for bending a bending point between the bottom wall 11 and the second lateral wall 12 while varying the bending point, on the other hand, retaining an angle of the first lateral wall 12 with respect to the bottom wall 11 as it is.SELECTED DRAWING: Figure 9
