Abstract
To assemble a positioning member, which is to come into abutment with a liquid ejection apparatus, to a liquid ejection member, the present disclosure has adjustment parts for adjusting positions of the positioning member and the liquid ejection member and securing parts for coupling and securing the positioning member and the liquid ejection member and thereby couples and secures the positioning member and the liquid ejection member. Thus, the positions of ejection ports of the liquid ejection head set in the liquid ejection apparatus and reference positions can be positioned with high accuracy.
Claims13
