できる。According to the present invention, the lubricating oil splashed up to almost the highest position of the transmission housing by the gear collides with the fixed bolt boss portion arranged above the lubricating oil collecting passage. Lubricating oil particles are attached and collected on the fixing bolt boss portion.
Then, the lubricating oil adhering to the surface of the fixing bolt boss drops as an oil drop and drops downward, but since the fixing bolt boss is extended above the lubricating oil collecting passage in the same direction as the fixing bolt boss, it is fixed. Lubricating oil drops falling from the surface of the bolt boss are collected in the lubricating oil collecting passage. Therefore,
For example, unlike the conventional lubricating device disclosed in Japanese Utility Model Laid-Open No. 60-189663, it is not necessary to provide a lubricating oil receiving portion for collecting the lubricating oil splashed by the gear, and the lubricating oil collecting passage is Since it can be formed into a simple shape such as an ordinary gutter, the lubricating device can have a simple and lightweight structure.

同様の構成となっている。As shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the gear-type transmission 1 uses the torque of the input shaft 2 at a predetermined gear ratio corresponding to the selected gear stage. It has a basic configuration that is transmitted to the third party. A synchronous meshing device 4 is provided to synchronize the rotation on the input shaft side and the rotation on the output shaft side when shifting to a desired gear. The synchronous meshing device 4 is, for example, 4 if the synchronous meshing device 4 for the third speed and the fourth speed, which is located substantially in the center of the gear type transmission 1, is taken as an example.
At the time of high speed, the torque of the fourth speed gear 5 loosely fitted to the output shaft 3 is sequentially applied to the spline portion 6 of the fourth speed gear 5 by a hub sleeve 7, and the inner peripheral portion is spline fitted to the output shaft 3. On the other hand, the outer peripheral portion is adapted to be transmitted to the output shaft 3 via the hub sleeve 7 and the clutch hub 8 which is spline-fitted. When shifting to the 4th speed, the synchronizer ring 9 synchronizes the rotations of the input side and the output side in a normal manner. Although not described, the other gears have the same configuration.

る。As is apparent from FIG. 3, the fixing bolt boss portion 16 projects downward from the lower surface of the upper wall of the housing 13 and extends in the longitudinal direction of the gear type transmission 1.
Lubricating oil particles splashed up by each gear 4 and scattered obliquely upward in the width direction of the gear type transmission 1 as shown by arrows C and D collide with the fixed bolt boss portion 16 and adhere to the surface thereof. Then, the lubricating oil attached to the surface of the fixing bolt boss portion 16 collects into oil droplets of the lubricating oil, and when the oil droplets exceed a certain size, they drop and enter the lubricating oil collecting passage 11. Since the fixing bolt boss portion 16 is formed in the vicinity of the upstream end 11a of the lubricating oil collecting passage 11, that is, above the portion having the highest vertical level, the fixing bolt boss portion 16 is provided at the portion having the highest level in the lubricating oil collecting passage 11. The dropped lubricating oil flows down the lubricating oil collecting passage 11 from the upstream side to the downstream side, and is supplied to a predetermined lubrication required portion.
