Abstract

La presente invención proporciona un generador AC para un vehículo, en el cual un recipiente de resina (26) incluye porciones convexas (33) formadas sobre una superficie circunferencial externa del recipiente de resina (26) a fin de extenderse en una dirección axial del recipiente de resina (26) para entrar en contacto a presión con una superficie de pared circunferencial interna de una porción de alojamiento de soporte de ramal conductor contrario (24), y porciones convexas (34) formadas sobre una superficie circunferencial interna del recipiente de resina (26) a fin de ser opuestas a las porciones convexas (33) . Las porciones cóncavas (34) permiten el desplazamiento de las porciones convexas (33) en una dirección radialmente hacia dentro del recipiente de resina (26) Mediante una fuerza elástica generada por el desplazamiento de las porciones convexas (33), el recipiente de resina (26) se integra con la porción de alojamiento de soporte de ramal conductor contrario (24).
