対する垂直度やピン相互間のピッチ間精度および機械的
な強度が要求される。A plurality of chassis boss seats are usually installed on the chassis, and mechanical parts, lever mechanisms, guide rollers, etc. are attached using pins erected on the chassis boss seats. Therefore, this pin is required to have perpendicularity to the chassis, pitch accuracy between the pins, and mechanical strength.

【発明が解決しようとする課題】しかし上記従来の方法
には、次のような欠点があった。[Problems to be Solved by the Invention] However, the above conventional method has the following drawbacks.
【０００５】（１）ボス部分を成形する時の樹脂の収縮
現象により、金属板の穴と樹脂成形部との間に隙間がで
き、ボス座のピッチ間精度が悪い。(1) Due to the shrinkage phenomenon of the resin when molding the boss portion, a gap is created between the hole in the metal plate and the resin molded portion, resulting in poor pitch accuracy of the boss seat.
【０００６】（２）樹脂成形部が厚肉のため、均一冷却
が困難となり、ボス座の中央穴に圧入した金属軸の金属
板に対する垂直度が悪い。(2) Since the resin molded part is thick, uniform cooling is difficult, and the perpendicularity of the metal shaft press-fitted into the central hole of the boss seat with respect to the metal plate is poor.
【０００７】（３）ボス座に圧入した金属軸の横方向に
荷重をかけた場合の強度が不足する。(3) The metal shaft press-fitted into the boss seat lacks strength when a load is applied in the lateral direction.

ある。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which a cylindrical protrusion 2 is formed on the surface of a metal plate 1 of a chassis by burring, etc., and the outer circumference, inner circumference and thickness direction of the metal plate are A boss portion 3 continuous to both sides of the boss portion 3 is molded with resin, and a metal pin 4 is press-fitted into the central hole of the boss seat thus created, and has the following features.
【００１２】（１）ボス部分を成形する時の樹脂の収縮
により、金属板に加工された円筒状突起部外周を締付け
るためにボス座のピッチ間精度は非常に良くなる。(1) Due to the shrinkage of the resin when molding the boss portion, the pitch accuracy of the boss seat becomes very good because it tightens the outer periphery of the cylindrical projection formed on the metal plate.
【００１３】（２）金属板の円筒状突起を挟んだ構成に
なり、樹脂部を薄肉化し、均一冷却が可能となり、金属
板に対する垂直度が良くなる。(2) The structure is such that the cylindrical protrusion of the metal plate is sandwiched between the resin parts, the resin part is thinned, uniform cooling is possible, and the perpendicularity with respect to the metal plate is improved.
【００１４】（３）金属板の円筒状突起によりボス座の
中央穴に圧入した金属軸の横方向への荷重に対する強度
は非常に高くなる。(3) Due to the cylindrical protrusion of the metal plate, the strength against the lateral load of the metal shaft press-fitted into the central hole of the boss seat is extremely high.
