Abstract

　La présente invention vise à procurer une composition de résine qui permet l'utilisation d'une résine pouvant être obtenue facilement et économiquement et facilite une production de masse, et grâce à laquelle il est possible de former un élément coulissant présentant d'excellentes propriétés coulissantes y compris une résistance à l'usure. La composition de résine pour élément coulissant comprend une résine thermoplastique, du graphite, et un composé à base de bore. Ladite résine thermoplastique est de préférence un polysulfure de phénylène, un polyamide, un polyéther éther cétone, ou une combinaison de ceux-ci, et est plus préférablement un polyéther éther cétone. La teneur dudit composé à base de bore est de préférence comprise entre 0,2 et 5 parties en masse, inclus, par rapport à 100 parties en masse de ladite résine thermoplastique. Le composé à base de bore et/ou le graphite peuvent être inclus en partie ou en totalité dans une poudre de résine qui contient une résine phénolique et le composé à base de bore et/ou le graphite. La taille maximale des particules de ladite poudre de résine est de préférence de 0,04 mm ou moins.
