PURPOSE:To provide a compact step-less transmission by disposing a variable width pulley at the primary side and fixed and movable pulleys opposed in parallel at the secondary side to form a fluid chamber between the fixed pulley and the movable pulley located at the central section. CONSTITUTION:Respective fixed pulleys 4, 7 at the primary side are opposed to respective by movable pulleys 14, 17 at the secondary side. The fixed pulleys 4, 7, 15, 18 and the movable pulleys 5, 8, 14, 17 at the primary side and at the secondary side are provided at the reverse positions. Also, oil pressure chambers 10, 20 are formed between both pulleys 4, 8 and 14, 18 and oil pressure chambers 13, 24 are formed at the primary and secondary sides. Thus, variable width pulleys can be disposed on respective shafts to provide a compact transmission without enlarging size of the transmission. |
