Connection structure between resin component and metal component and ink-jet head comprising the same
摘要：
The first passage component and the second passage component are fixed with each other as the male screw part is screw-engaged with the female screw hole while the cylinder part is inserted into the through-hole. The second passage component has a convex contacting the head and a spaced surface spaced apart from the head in the axial direction, both in a first annular confronting area confronting the head of the stepped screw, at a surrounding of the through-hole of the third surface. The axial length of the cylinder part is same as the length of a line segment extending to the second surface from the leading end of the convex in the axial direction, while the axial length of the cylinder part is smaller than the length of the line segment until the male screw part is screw-engaged with the female screw hole.
摘要（中）：

当第一通道部件和第二通道部件被插入到通孔中时，外螺纹部分与阴螺纹孔螺纹接合，彼此固定。 所述第二通道部件具有与头部接触的凸起以及与所述头部在轴向上间隔开的间隔开的表面，所述第二通道部件在与所述阶梯螺钉的头部相对的第一环形面对区域中位于所述第三通孔的通孔的周围 表面。 圆筒部的轴向长度与从轴向的凸起的前端延伸到第二面的线段的长度相同，而圆筒部的轴向长度小于线段的长度 直到外螺纹部分与内螺纹孔螺纹接合。
