<p><P>PROBLEM TO BE SOLVED: To provide a lubricating oil passage structure for an automatic transmission, capable of supplying a lubricating oil in a suitable amount to respective positions of a transmission mechanism regardless of the number of revolutions of a rotating shaft. <P>SOLUTION: In the automatic transmission 1, the transmission mechanism 2 is arranged in the vicinity of an input shaft 11A and an intermediate shaft 11B, and the lubricating oil is introduced into the lubricating oil passage structure 10 formed in the input shaft 11A and the intermediate shaft 11B from an oil pump body 4, and is delivered to the transmission mechanism 2. As the lubricating oil passage structure 10, an axial direction oil passage 21b allotted for a front side part AreaF of the transmission mechanism 2 and axial direction oil passages 22Ab and 22Bb allotted for a rear side part AreaR of the transmission mechanism 2 are formed with different lengths in the input shaft 11A and the intermediate shaft 11B, and the lubricating oil is independently supplied to the front side portion AreaF from the axial direction oil passage 21b through a delivery hole 21c and the rear side part AreaR from the axial direction oil passages 22Ab and 22Bb through a delivery hole 22c. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
