PROBLEM TO BE SOLVED: To provide a V-belt automatic transmission generating proper side load to a V-belt more suitable for engine torque to enhance efficiency of V-belt transmission. SOLUTION: A fixed boss shaft 2 of a fixed sheave half body A is rotatably disposed to an outer periphery of a driven shaft 1, a movable boss shaft 5 of a movable sheave half body B disposed to the outer periphery of the fixed boss shaft 2, along an axial direction to be slidable, and a push rod 8 is disposed in a driven shaft 1 along the axial direction to be slidable. The push rod 8 can be brought into contact with the movable sheave half body B through long holes formed respectively in the driven shaft 1 and the fixed boss shaft 2. Movement of the push rod 8 is controlled by a shift cam 15 rotated by an electric motor 18. COPYRIGHT: (C)2007,JPO&INPIT
