Claims

[Scope of utility model registration request]

The movable V pulley includes a fixed V pulley piece, and a movable V pulley piece disposed on the axial extension of the fixed V pulley piece so as to be slidable in the axial direction in opposition to the fixed V pulley piece.
In the variable speed pulley having a configuration in which the width of the V groove between the movable V pulley piece and the fixed V pulley piece is varied by sliding of the pulley piece, a support portion that supports the movable V pulley piece is positioned near the V belt position. A speed change pulley, characterized in that it is disposed at a position with a large rotation radius around a shaft, and a bearing member is interposed in the support portion.
