Abstract

A sheave for a continuously variable transmission (100) includes: a boss member (110) being made of a first metal material; and a sheave member (120) that is made of a second metal material which is a different kind from the first metal material, the sheave member (120) including a sheave surface (121) and a rear surface (122). The sheave member is mounted on an attachment region (AR) being a part of an outer peripheral surface (110os) of the boss member (110) via plastic flow coupling. The attachment region has a stepped shape that includes a first region (R1) having a relatively small diameter, a second region (R2) having a relatively large diameter, and a step surface (SS1) located at a boundary between the first region and the second region. The first region, the step surface, and the second region are disposed in this order from the sheave surface side toward the rear surface side, and the sheave member abuts with the step surface.
