Abstract: An oil-feeding member (100) catches oil picked up by a gear, and is provided with a gutter (132) guiding the oil from one side to the other of a transmission in an axial direction. The gutter (132) has a bottom which is divided into a first bottom portion (141) and a second bottom portion (142). The second bottom portion (142) is provided with an oil-dripping hole (142a, 142b). The first and second bottom portions (141, 142) are configured so that (i) the oil flows over only the first bottom portion (141) toward the other side if an amount of the oil caught by the oil-feeding member (100) is smaller than or equal to a predetermined amount, and that (ii) the oil flows over both of these bottom portions (141, 142) toward the other side if the amount of the oil is greater than the predetermined amount.

Abstract: An oil feeding member (100), catching oil picked up by a gear, includes a gutter guiding the oil from one end to the other end of a transmission in its axial direction. The gutter is comprised of a first gutter (131) and a second gutter (132). A portion of the oil feeding member closer to the one end includes a catching wall (124) standing between the first and second gutters, catching the oil picked up by a speed change gear (21, 22) serving as the gear, and guiding the oil into the first gutter. A transmission case (2) includes a guiding portion (150) guiding, into the second gutter, the oil picked up by the speed change gear and deposited on a ceiling surface (2c) of the transmission case.

Abstract: A guide groove including a groove section extending from the vicinity of an entrance of a main passage to a side opposite the entrance is formed on the inner circumferential surface of a main passage. The groove section is provided in an inclined fashion with respect to the axial direction such that lubricating oil inside the groove section is sent towards the side opposite the entrance by rotation of a rotary shaft in a predetermined direction. Of a plurality of subsidiary passages, the entrance of a subsidiary passage that is most distant from the entrance of a main passage is disposed in the guide groove. In a lubrication structure for a transmission, insufficient lubrication is effectively prevented in parts requiring lubrication corresponding to the subsidiary passages, irrespective of the positions of the subsidiary passages in the axial direction, while avoiding increase in the size of the transmission.

Abstract: A gear train for first gear, a gear train for another specified forward gear and a gear train for reverse gear are arranged in order from the opposite side to an engine. A synchronizer for reverse gear is arranged on a first countershaft between a first driven gear of the gear train for reverse gear and a driven gear of the gear train for first gear. The synchronizer for reverse gear connects the first driven gear of the gear train for reverse gear and the driven gear of the gear train for first gear when a reverse shift is selected. Accordingly, the manual transmission which can shorten its axial size can be provided.

Abstract: The present invention is directed to a transmission capable of minimizing the number of speed-change driven gears on a first countershaft to ensure a layout space in an engine compartment of a vehicle, and reducing a driving torque to be applied to a second countershaft to facilitate downsizing of the transmission. In the transmission, the first countershaft 2 is arranged at a position above an input shaft 1, and a first-speed driven gear 14 and a second-speed driven gear 24 are provided on the first countershaft 2.

Abstract: A transmission equipped with a cable-type shift device comprises a control shaft to control a shift change with rotation and axial-direction movement thereof, an outer lever to be rotated by a shift-direction operation of a change lever, and a counterweight to rotate with the rotation of the control shaft, but not to move with the axial-direction movement of the control shaft. The counterweight includes first and second weight portions, an arm portion to interconnect these weight portions, and a support axis disposed so as to extend vertically. The support axis rotatably supports a substantial gravity center of the first and second weight portions and the arm portion. Accordingly, the counterweight can be supported smoothly and the shift feeling can be improved properly with a relatively small force for the select-direction operation of the change lever.
