<p>A shifting and power transmission device having a hydrostatic stepless shifting section (20) into which the output of an engine (1) is inputted; a planetary power transmission section (3a) having planetary power transmission mechanisms (PF, PR) for combining drive force outputted from the hydrostatic stepless shifting section (20) and engine drive force not subjected to a shifting action by the hydrostatic stepless shifting section (20) and also having output members (41, 42); and a shifting and output section (3b) having an output shaft (70) and outputting the combined drive force, outputted from the output members (41, 42), in multiple speed ranges from the output shaft (70). The shifting and output section (3b) has power transmission mechanisms (71-74) arranged between the output shaft (70) and the output members (41, 42) and also has clutches (CL1-CL4) arranged corresponding to the power transmission mechanisms, respectively.</p> |
