A continuously variable transmission having a plurality of planetary rollers arranged around a main shaft. Both ends of a rotary shaft of each of the planetary rollers are held so as to be capable ofbeing displaced in the radial direction with respect to the main shaft. Each planetary roller has a first inclined surface in contact with an input rotating body and as second inclined surface in contact with an output rotating body. The inclination angle of the planetary rollers changes in accordance with the position of a movable ring in the axial direction. Thus, both the contact position of the first inclined surface with respect to the input rotating body and the contact position of the second inclined surface with respect to the output rotating body change. Therefore, the transmission gear ratio between the input rotating body and the output rotating body can be switched. Furthermore, the first inclined surface of the planetary rollers is a spherical surface. Therefore, the directionand magnitude of pressure generated at the contact point of the first inclined surface and the input rotating body does not easily change, regardless of the inclination angle of the planetary rollers.

    该无级变速器具有配置在主轴线的周围的多个行星滚轮。行星滚轮的自转轴的两端部以能够相对于主轴线沿径向移位的方式被保持。各行星滚轮具有:第1倾斜面,其与输入旋转体接触;以及第2倾斜面,其与输出旋转体接触。行星滚轮的倾斜角度根据可动环的轴向的位置而变化。于是,第1倾斜面与输入旋转体的接触位置和第2倾斜面与输出旋转体的接触位置分别发生变化。由此,能够切换输入旋转体与输出旋转体之间的变速比。并且,行星滚轮的第1倾斜面是球面状。因此,无论行星滚轮的倾斜角度如何,在第1倾斜面与输入旋转体的接触点处产生的压力的方向和大小都不容易变化。
