BEARING MEMBER FOR PEDAL ARM AND PEDAL ARM
摘要:
A bearing member for a pedal arm, which is a tubular bearing member which is disposed in a circular mounting hole formed in a plate member that constitutes the pedal arm and through which a connecting shaft having a cylindrical outer peripheral face is passed so as to be rotatable relative to the bearing member, the bearing member includes: a large-diameter tubular portion having an external diameter larger than a diameter of the mounting hole and having a cylindrical inner peripheral face along which the connecting shaft is extended so as to be rotatable relative to the cylindrical inner peripheral face; a small-diameter tubular portion that is formed continuously and integrally with the large-diameter tubular portion in an axial direction of the large-diameter tubular portion, that has a cylindrical outer peripheral face with a diameter smaller than that of the mounting hole, and that has the cylindrical inner peripheral face formed continuously from the large-diameter tubular portion along an overall length of an axial length t of the small-diameter tubular portion; and a thin-wall tubular portion that is formed continuously with the small-diameter tubular portion in the axial direction so as to be located on a side opposite to the large-diameter tubular portion and so as to be integral with the small-diameter tubular portion, that has an inner diameter larger than a diameter of the cylindrical inner peripheral face of the small-diameter tubular portion, and that has the cylindrical outer peripheral face formed continuously from the small-diameter tubular portion, by inserting the bearing member into the mounting hole from a thin-wall tubular portion side and swaging the thin-wall tubular portion, which projects from the mounting hole to an opposite side, in the axial direction, the bearing member being fixedly fitted to the mounting hole such that a peripheral portion of the mounting hole is held between a swaged portion bulged radially outward and the large-diameter tubular portion.
