PURPOSE:To prevent a transmission case from becoming longer as well as to aim at the promotion of its miniaturization and lightweightiness, by installing an oil passage to be interconnected to both of the oil passage of a drive pinion shaft and a lubrication flange being attached to the transmission case. CONSTITUTION:In a lubricating part of a hydraulic clutch for a running transmission mechanism, there is provided with each of oil passages 01 and 02 in a part between bearings 29 and 30 in front and in the rear of a bearing body 28 which is originally formed in thickness enough in order to be bearable to the thrust force of a drive pinion shaft 8 so that there is no need to install a new a special thick part for forming the oil passage, meaning that a transmission case 1 is in no case lengthened any longer, not to mention its lightweightiness, thus conducing to its miniaturization and lightweightiness. Since most of the length of these oil passages 01 and 02 as well as P1 and P2 is formed in the bearing body 28, troublesome on such work for drilling as in a construction that forms the whole length of the oil passage in the long transmission case 1 is thus eliminated. |
