Problems solved by technology

However, in this case, in order to prevent the strength reduction of the machined part, it is necessary to make the thickness of the inner ring thicker, so the radial dimension may be increased by the amount by which the thickness of the inner ring is increased

Abstract

A manual transmission (10) includes a shaft (21) that has an axial oil passage (61) that extends in an axial direction of the shaft (21), and a radial oil passage (62) that is communicated with the axial oil passage (61) and extends in a radial direction of the shaft (21); an inner race (37) that is provided on an outer periphery of the shaft (21) and includes an oil passage (72) that is communicated with the radial oil passage (62) and extends in the radial direction of the shaft (21); a rolling element (36) that is provided on an outer periphery of the inner race (37); and a cylindrical pin (81) that is provided along the radial oil passage (62) and the oil passage (72), on an inner peripheral side of the radial oil passage (62) and the oil passage (72).

Description

technical field [0001] The present invention relates generally to a manual transmission, and more particularly, to a manual transmission provided with a mechanism for supplying lubricating oil to bearings supporting idler gears. Background technique [0002] As a related manual transmission, for example, Japanese Patent Application Publication No. 2010-236589 (JP 2010-236589 A) describes a manual transmission aimed at further shortening the axial dimension. The manual transmission described in JP 2010-236589 A has an input shaft, a first countershaft, a second countershaft, and a plurality of gears provided idly rotatable on these shafts via bearings such as needle bearings. [0003] In addition, Japanese Patent Application Publication No. 2009-63152 (JP 2009-63152 A) and Japanese Patent Application Publication No. 2012-154444 (JP 2012-154444 A) also describe various manual transmissions. [0004] In the manual transmission described in JP 2010-236589 A, as means for supply...
