Beschreibung
Zusammenfassung:	Disclosed is a shift power transmission apparatus for readily suppressing or avoiding size increase thereof. The apparatus includes an input shaft (22) receiving engine drive force, a hydraulic continuously variable transmission (30) driven by the input shaft (22), a planetary power transmission section (40) combining drive force from the input shaft (22) and output from the hydraulic continuously variable transmission (30) for outputting the combined drive force, and an output rotary member (24) outputting power to a travel apparatus. The planetary power transmission section (40) and the output rotary member (24) are arranged on a side of the hydraulic continuously variable transmission (30) associated with an engine-coupled side of the input shaft (22). The drive force is inputted to the planetary power transmission section (40) from a portion between the engine-coupled side and the hydraulic continuously variable transmission-coupled side of the input shaft (22).
