PROBLEM TO BE SOLVED: To provide a speed change transmission device that can easily be suppressed and avoided in the enlargement of the device.SOLUTION: The speed change transmission device comprises: an input shaft 22 that is input with an engine drive force; a hydraulic continuous variable transmission 30 driven by the input shaft 22; a planetary transmission part 40 which synthesizes the drive force of the input shaft 22 and an output of the hydraulic continuous variable transmission 30, and outputs the synthesized drive force; and an output rotating body 24 which outputs power to a traveling device. The planetary transmission part 40 and the output rotating body 24 are arranged at the same side as a side at which the engine connecting side of the input shaft 22 is positioned with respect to the hydraulic continuous variable transmission 30. The drive force is inputted to the planetary transmission part 40 from a region between the engine connecting side of the input shaft 22 and the hydraulic continuous variable transmission side.
