PROBLEM TO BE SOLVED: To supply lubricating oil surely and with good efficiency on necessary positions for each shaft in the case where lubricating oil is reduced to some extent by supplying lubricating oil toward necessary positions for each shaft in a series passage, in a shaft system which consists of an input shaft, an output shaft, a counter shaft, and a reverse idling shaft. SOLUTION: Oil collected in an oil pan 20 is entered into an oil chamber 22 through a connecting passage 21. Oil flows from an oil receiving part 22a toward an oil sump part 22b, an in-shaft inner oil passage Lr of a reverse idling shaft. In this case, the height of the reverse idling shaft is set some lower than that of an input shaft Si. When oil entered into the oil sump part 22b is spilled over from the oil passage Lr, oil is entered into the bearing support part 22c of the input shaft Si so as to lubricate a bearing Bil. After that, oil flows into the bearing support part 22e of a counter shaft Sc through the oil sump part 22d. Oil is guided to a shaft end cover 23, and is led to the in-shaft oil passage Lc of the counter shaft Sc so as to lubricate the bearing of a free rotating gear 5Gc for 5 speed. |
