PROBLEM TO BE SOLVED: To simplify a complicated structure by unnecessiating the separate installation of an advance/retreat changeover of a conventional hydraulic transmission in which the output rotation is continuously variable by arranging a variable hydraulic device and a differential hydraulic device on one shaft. SOLUTION: In the transmission in which a hydraulic continuously variable transmission integrally constituted of the variable hydraulic device 32 and the differential hydraulic device 33 is provided on an output shaft 30 from a driving source, and an output body 37 of the hydraulic continuously variable transmission is constituted of being relatively increasable/decreasable to the output shaft, an advance/retreat changeover device 21 is interlocked and connected to the output body, and at the same time, a changeover body of the advance/ retreat changeover device is interlocked and connected to an advance/retreat changeover operation tool provided to an operation part.
