Document Type and Number:
WIPO Patent Application WO/2015/045847
Kind Code:
A1
Abstract:
A driven pulley for a stepless transmission is configured so that the driven pulley does not require grease, and consequently the slipping of a clutch, etc. is prevented and cost is reduced by a reduction in the number of seal parts. This movable sheave structure is provided with: a boss (5) for a stationary sheave; a boss (6) for a movable sheave; a cam mechanism (7); first and second resinous members (16, 17); and a resinous collar (21). The cam mechanism (7) is provided to the boss (5) for a stationary sheave and to the boss (6) for a movable sheave and applies axial thrust force to the boss (6) for a movable sheave. The first and second resinous members (16, 17) constitute slide sections located between the boss (5) for a stationary sheave and the boss (6) for a movable sheave. The resinous collar (21) constitutes the slide section of the cam mechanism (7).
