The one described in Publication No. 0431 is known. As shown in FIG. 9, the clutch hub 1 is disposed inside a clutch drum 3 that is locked to a first shaft 2 as an output shaft and has spline teeth 3A on the inner circumferential surface of the cylindrical portion, for example, and serves as an input shaft. It is used by being locked to the second shaft 4.

面に導くのである。One end surface of the clutch hub 1 is open, and a boss portion IB is formed at the other end, and the clutch hub 1 is formed as a whole from a plate-shaped material by drawing. Further, the appropriate number of spline teeth IA includes drive plates 5.5. ..., driven plate 6.6. ...An oil passage hole is drilled to supply oil to the frictional engagement surface between. However,
The centrifugal force caused by the rotation of the clutch hub 1 causes the boss portion IB to
The oil passing through the shaft is guided to the friction engagement surface through the oil passage hole.

。[Problems to be Solved by the Invention] However, in such a clutch hub 1, the back surface of the spline ilA is flat due to the nature of the drawing process, and one end surface is open. Most of the oil that comes in flows out from the open end without being guided to the oil passage hole, which tends to result in insufficient oil supply to the frictional engagement surface between the drive plate and the driven plate, resulting in seizure, etc. was there.

の問題があった。As a countermeasure for the above, it may be possible to attach a separate member to the open end surface by means such as welding in order to prevent oil from flowing out from the open end, but such a method increases costs due to increased man-hours. There is a problem in that accuracy is reduced due to thermal distortion caused by welding heat, and there are also problems in that the direction of assembly is restricted when the drive plate is assembled.

It is a sectional view taken along the line BB in the figure. In the above diagram, 10 is the clutch hub Osumi, I
OA is a cylindrical portion, and 10B is a boss portion. IOC is a spline tooth formed by drawing together with the cylindrical portion 10A, 100 is an oil passage hole drilled in an appropriate number of spline teeth, and 10E is an l press slit formed in the spline tooth 10C by pressing.

Ｃの中心部を押圧することによって形成する。Thus, the press slit IOH forms an oil outflow prevention weir 10F on the back surface of the spline tooth 10G. The press slit IOE is made by shifting the upper mold and the lower mold in the axial direction of the clutch hub, and then using the upper mold to open the slit teeth 10.
Form by pressing the center of C.

となる。The feature of this processing is that it is performed without changing the basic tooth shape of the slit teeth in any way, as is clear from Fig. 3. By doing this, as shown in Fig. 4, the clutch plate 2o such as the drive plate etc. Since it can be installed from either the (i) direction or the (i) direction, the assembly work becomes easier.

通路孔１０Ｄに導かれるのである。Thus, the oil flowing along the boss portion 10B due to the centrifugal force caused by the rotation of the clutch hub IO is supplied between the clutch plates 20 from the back surface of the spline tooth 10G, passing through the oil passage hole 10D. On the other hand, spline tooth 10C
Since the oil flowing along the back surface of the boss portion 10B toward the open end is stopped by the oil spill prevention dam 10F, most of the oil flowing along the boss portion 10B is guided to the oil passage hole 10D. .

となり安価にできる。FIG. 5 shows a second embodiment of the present invention. In this embodiment, the oil spill prevention weir 10F is formed by punching, rather than by uniform press slits up to the open end as in the previous embodiment. This is based on LOG. This method is based on the weir 1
Although 0F cannot be formed so high, it is extremely easy to process and can be made at low cost.

イン歯１０Ｃの表面との段差部１０１１が形成される。FIG. 6 shows a third embodiment of the present invention, in which an oil spill prevention weir 10F is formed over the entire width of the vehicle in the rotational direction of the spline teeth 10C, and its formation by press working is the same as in the first embodiment. Similarly, the upper mold and lower mold are shifted in the axial direction of the clutch hub, but the upper mold has spline teeth of 10G.
This is done by pressing the entire tooth width, and a stepped portion 1011 with the surface of the spline tooth 10C is formed.

の形状が幅広となるため耐久上有利となる。According to this, the spline tooth 10 is formed by the stepped portion 10H.
Since the basic tooth shape of C is changed, the mounting direction of the clutch plate 20 is limited to only one direction, but since the oil spill prevention dam 10F spans the entire tooth width in the rotational direction with the spline tooth 10C, the damming efficiency is The shape of the upper die of the press is wide, which is advantageous in terms of durability.

０が形成されるのである。7 and 8 show a fourth embodiment of the present invention, in which an oil passage hole 100 and an oil outflow prevention dam 10F are formed at the same time. That is, a part of the spline tooth 10G is cut and raised by punching to form the louver portion 10K. Thus, an oil spill prevention weir 10F is formed on the end face of the looper portion 10, and the oil passage hole 10F is formed with a slit hole.
0 is formed.
このようにすると、オイル通路孔１００を形成する工程
