Abstract

Se proporciona un miembro de tornillo externo que se puede usar como un tornillo autorroscante, y tambien se puede usar como un perno adaptado para atornillarse en un tornillo interno, mientras se eliminan las materias extranas adheridas al mismo; se puede suprimir un aumento en el torque motor y se puede suprimir una cantidad de virutas que se generaran; ademas, en los casos en que el miembro de tornillo externo se usa para el tornillo interno con materia extrana adherida al mismo, es posible no solo eliminar la materia extrana de manera confiable, sino tambien descargarla suavemente, lo que permite evitar atascos de la materia extrana; En una parte de una rosca del tornillo (5) que se extiende desde una porcion roscada conica (32) a una porcion roscada paralela (31), se forman porciones convexas (4) que sobresalen en una direccion radialmente externa desde una cresta de la rosca del tornillo (5); una cara extrema del lado del atornillado (4d) de la porcion convexa (4) forma un plano inclinado que se eleva gradualmente en una direccion opuesta a la direccion del atornillado de la rosca del tornillo desde una posicion de raiz de la cara extrema (4d) en el lado de la cresta de la rosca del tornillo hacia una cresta (4a) de la porcion convexa (4) para alcanzar la cresta (4a) de la porcion convexa (4).
