Claims

[Scope of utility model registration request]

A pulley shaft provided with a fixed pulley, a movable pulley having a boss portion into which the pulley shaft is slidably inserted, a first cylinder tube fixed to the movable pulley, and a first cylinder tube supported by the pulley shaft. a second cylinder tube slidably inserted into the second cylinder tube, a sleeve concentrically housed in the second cylinder tube, and a support member provided between the second cylinder tube and the sleeve and supporting both ends of the sleeve; a passage formed between the second cylinder tube and the sleeve; a first piston that is continuous with the sleeve and into which the boss part is slidably inserted; and a first piston which is fixed to the boss part and is slidably inserted into the sleeve. a second piston, a first cylinder chamber defined between the movable pulley, the first cylinder tube, the second cylinder tube, and the first piston and containing a fluid that presses the first piston toward the second piston; and,
defined between the pulley shaft, the second cylinder tube, the sleeve and the second piston;
A pulley structure for a wrap-around transmission type continuously variable transmission, comprising: a second cylinder chamber in which fluid to be pressed toward the piston is stored and communicated with the first cylinder chamber via the passage.
