Abstract

A power transmission device (10) for a work vehicle (100) includes a transmission (11) including an input shaft (20) rotationally driven by a prime mover (103), a continuously variable transmission (30), a planetary gear mechanism (40), and a plurality of transmission gears (50). The first planetary gear mechanism (41) includes a first ring gear (41R), a first sun gear (41S), and a first planetary gear (41P). The second planetary gear mechanism (42) includes a second ring gear (42R), a second sun gear (42S), and a second planetary gear (42P). The first planetary gear (41P) further includes a third planetary gear (43P) that meshes with the second planetary gear (42P). An outer diameter dimension (RS1) of the first sun gear (41S) is larger than an outer diameter dimension (RS2) of the second sun gear (42S), and an inner diameter dimension (RR2) of the second ring gear (42R) is larger than an inner diameter dimension (RR1) of the first ring gear (41R).
