との間に設けられるブッシュの構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle door hinge, and more particularly to a structure of a bush provided between a shaft thereof and a hinge piece.
従来の自動車のドアヒンジには、軸とヒンジ片との間
に、それらの相対回転を円滑にするためのブッシュが設
けられている。A conventional vehicle door hinge is provided with a bush between the shaft and the hinge piece for smoothing relative rotation between them.
このようなブッシュとしては、一方のヒンジ片の軸孔内
に嵌合される筒部と、その筒部の一端に連設された拡径
鍔部とを有するもの、及びこれに、筒部から拡径鍔部に
かけてスリットを設けたもの等がある。As such a bush, one having a tubular portion fitted in the shaft hole of one hinge piece and a diameter-expanding flange portion connected to one end of the tubular portion, and from this, the tubular portion For example, there is a slit provided on the expanded collar portion.
上述のような従来のブッシュは、通常、その内面とその
中に嵌合された軸との間で相対回転するように、内面を
円滑面とし、かつ外周面は、ヒンジ片の軸孔内に嵌合し
たときヒンジ片と相対回転しないように、不円滑面とし
てある。The conventional bush as described above usually has a smooth inner surface and an outer peripheral surface in the shaft hole of the hinge piece so as to rotate relatively between the inner surface and the shaft fitted therein. It is a non-smooth surface so that it does not rotate relative to the hinge piece when fitted.
しかし、ブッシュは、本来的に、ヒンジ片に対して相対
回転することは避けられず、特に、スリットを設けたブ
ッシュにあっては、ヒンジ片の軸孔内への圧入力が弱い
ため、ヒンジ片に対して相対回転するおそれが大であ
