摘要： A hydraulic continuously variable transmission has a variable displacement type first hydraulic system having a first plunger and a plunger abutting section which actuates the first plunger, and a second hydraulic system having a second plunger and provided with an output rotary section which rotates with abutment on the second plunger. A cylinder block rotates about an axis and has a first plunger hole and a second plunger hole which respectively retain the first and second plungers. A hydraulic closing circuit connects the first and second plunger holes and circulates a working oil between the first and second plunger holes. The continuously variable transmission has a distributing valve for controlling circulation of the working oil in the hydraulic closing circuit, a valve hole, formed in the cylinder block, for retaining the distributing valve, and a shaft which penetrates the cylinder block. The shaft and the cylinder block rotate synchronously and the output rotary section is rotatably supported around the shaft. The valve hole is formed in parallel to the shaft, and restriction means is arranged inclined with respect to the shaft and rotates in synchronism with the cylinder block to reciprocate the distributing valve with the distributing valve being restricted.
