PURPOSE:To permit the superior circulation of working oil in the normal and reverse revolution of an oil pump by arranging the working-oil suction port and the oil discharging port of an oil pump driven through the relative revolution between the input and output shafts of a fluid coupling in a fluid transmission apparatus, lower than the liquid level of an oil reservoir. CONSTITUTION:The working-oil supplying and discharging mechanism 2 of a fluid transmission apparatus equipped with a fluid coupling not shown in the figure and an oil pump which is not shown in the figure and driven through th relative revolution between the input and output shafts of the fluid coupling is installed into the fluid transmission apparatus housing 10A and the differential case 10B of a speed change gear case 10, and an oil reservoir 24 is formed in the lower part in the case 10B. The oil level 241 of the oil reservoir 24 is set a little below an axle 77. The working-oil suction port 251 of an oil pump in a working-oil supplying passage 25 and the oil discharging port 265 of a working-oil discharging passage 26 are arranged at the position lower than the oil level of the oil reservoir 24, in traveling and in stop. |
