Driven pulley for a continuously variable transmission

A driven pulley for a continuously variable transmission comprising:

• a fixed sheave;
• a movable sheave operatively connected to the fixed sheave, the movable sheave being movable axially relative to the fixed sheave;
• a spring biasing the movable sheave axially toward the fixed sheave;
• and
• at least one roller assembly connected to one of the fixed sheave and the movable sheave,
• another one of the fixed sheave and the movable sheave having at least one ramp configured for abutting the at least one roller assembly;
• each roller assembly of the at least one roller assembly having:
• a pin defining a radially extending pin axis, the pin having:
• a first pin portion received in an aperture defined in the one of the fixed sheave and the movable sheave;
• a second pin portion extending radially from the one of the fixed sheave and the movable sheave;
• and
• an annular flange disposed radially between the first pin portion and the second pin portion, the flange having a first annular width, the flange abutting a surface of the one of the fixed sheave and the movable sheave surrounding the aperture;
• and
• a roller disposed on the second pin portion, the roller being rotatable about the pin axis, the roller being slidable radially along the second pin portion, the roller having at least one annular portion, the at least one annular portion of the roller having a second annular width,
• the first annular width being at least half of the second annular width.
