    • 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.
    • 树脂皮带轮包括:外圆筒部,其外周面与外圆筒部的内周面和外筒部的外周面相连接;外筒部, 圆柱形部分由树脂材料形成。 这些肋沿轴向方向相对于径向虚线设置成朝向圆周方向倾斜。 肋的径向外端部形成为使得各个径向外端部相对于径向假想线的倾斜角度随肋的径向向外延伸而增加,肋的径向内端部形成为 当肋沿径向向内延伸时,相对于径向虚线的相应的径向内端部增加。
