Abstract
A resin pulley includes an outer cylindrical portion including an outer circumferential surface on which a belt is to be wound, an inner cylindrical portion, and a plurality of ribs connecting an inner circumferential surface of the outer cylindrical portion and an outer circumferential surface of the inner cylindrical portion, which are formed of a resin material. The ribs are provided so as to be inclined towards a circumferential direction relative to a radial imaginary line as viewed in an axial direction. Radially outer end portions of the ribs are formed such that inclination angles of the respective radially outer end portions relative to the radial imaginary line increase as the ribs extend radially outward, and radially inner end portions of the ribs are formed such that inclination angles of the respective radially inner end portions relative to the radial imaginary line increase as the ribs extend radially inward.
