In a transmission structure according to this invention, speed change ratios of input side first and second transmission mechanisms (50(1)-(2)) are set so that the rotational speed of a planetary second element (38) is same when an HST output is set to a second HST speed in a first transmission state and when a second transmission state is engaged, and the rotational speed of a planetary first element (36) is same when the HST output is set to the second HST speed in the second transmission state and when the first transmission state is engaged. The speed change ratios of output side first and second transmission mechanisms (70(1)-(2)) are set so that the rotational speed developed in a speed change output shaft (45) when the HST output is set to the second HST speed is same in the first and second transmission states.
