る。[Prior Art] Differential devices are known in automobiles. This differential device is
It absorbs the difference in rotational speed between the left and right drive wheels, and when the vehicle changes direction or turns, it self-helps by changing the rotational speed of the left and right wheels for smooth running. A normal differential gear always transmits the same torque to both left and right driving wheels.Therefore, if one wheel spins in the mud and the transmitted torque decreases, the transmission to the other wheel decreases. Torque also becomes small, which makes it impossible to escape.In order to improve this drawback, there is a differential limiting device.

低速回転側の伝達トルクが増大する。This difference! In the l1tI limiter, the driving force from the engine is equally transmitted to the left and right differential large gears 101 via the shaft 102a and the differential small gear 102. If the rotational speed of the left and right wheels differs and a differential occurs, the housing 1
00 and the large differential gear 101 rotate relative to each other. At this time, since a pressing force is applied to the grooved clutch plate 104 by the cam mechanism 107 or the like, a large number of grooved clutch plates 104
slide into contact with each other and friction torque is generated between the clutch plates 104, and this FJ friction torque becomes differential resistance torque,
Transmission torque on the low speed rotation side increases.

Ｉｌである。The above-mentioned grooved clutch plate 104 generally has a lattice-shaped oil retaining groove consisting of vertical grooves and horizontal grooves on its sliding friction surface. Here, the pitch of the oil retaining groove is, for example, 2 to 81
It is Il.

程とを順に行うことにしている。By the way, in forming the grooved clutch plate 104, there have conventionally been a process of degreasing the steel plate, a process of smoothing the surface of the steel plate, and a masking process on the surface of the steel plate except for the parts that will become vertical grooves and horizontal grooves. a process of drying the film, a process of immersing the steel plate in an etching solution and corroding only the parts that are not coated to form vertical and horizontal grooves through corrosion, a process of peeling the film from the steel plate. The process of punching out a clutch plate of a predetermined shape from a steel plate is performed in order.

で摺接する際に、騒音（チャタ音）の原因となり易い。Therefore, in the grooved clutch plate 104 formed by etching as described above, as shown in FIG. 12, the inner part of the oil retaining groove 104a is eroded and spread laterally than the sliding friction surface side. ing. If the inner part of the oil retaining groove 104a is eroded and spread laterally in this way, the lubricating oil that has entered the oil retaining groove 104a becomes difficult to come out to the sliding friction surface side of the grooved clutch plate 104a. Therefore, it becomes difficult to form a good oil film on the sliding friction surface of the grooved clutch plate 104. Therefore, when the sliding friction surface of the grooved clutch plate 104 makes sliding contact in the differential t111 limiter, noise (chattering sound) is likely to be caused.

If a grooved clutch plate 104 is formed, it is likely to be eroded laterally as the depth increases.
The depth of a is limited.

When the protruding portion 104b is formed in this manner, it is likely to cause noise (chattering sound) when the grooved clutch plate 104 slides in the differential t111 limiter.

The erosion continues as it is, and the problem of lubricating oil being discharged to the sliding friction surface side remains unresolved.

It is a grooved clutch plate, and at least one of the two sliding friction surfaces is formed by pushing the protrusion of the rolling roll during rolling, and the opposing distance gradually increases as the depth increases. The oil retaining groove has a small inner surface, and the peripheral edge of the opening of the oil retaining groove is formed of an arcuate portion having a curvature within a predetermined range, and the sliding friction surface is flattened and rolled.

保持溝の内側面は形成されている。The oil retaining grooves of the grooved clutch plate according to the present invention include a first groove group extending in one direction and a second groove group extending in a direction crossing the second groove group.
A typical example is a lattice-like groove consisting of a group of grooves. In some cases, the oil retaining groove may be formed as a groove extending radially in a straight or arcuate manner from approximately the center of the clutch plate. FIG. 5 shows an enlarged sectional view of the vicinity of the oil retaining groove. In this way, the protrusions of the rolling rolls are pushed in to form oil-retaining grooves, so as shown in Figure 5, the groove width gradually decreases toward the back of the groove. , the inner surface of the oil retaining groove is formed.

でえがくことができる。Here, the width of the groove on the sliding friction surface side, which is the surface of the grooved clutch plate having oil retaining grooves, varies depending on the size of the clutch plate, but is approximately 0.2 to 1.5 mm, particularly 0.2 to 1.5 mm.
5-Q, about 7 mm is preferable. The groove width L1 on the bottom side of the oil retaining groove varies depending on the size of the clutch plate, but is preferably about 0.2 to 1°Qmm, particularly about 0.3 to 0.4mm. In addition, the peripheral edge on the opening side of the oil retaining groove is
It varies depending on the size of the clutch plate, but it is 0.03 to 0.
．． It is desirable to form an arcuate portion with a curvature R of about 1 mm, especially about 0.05 to 0.06 mm. Also, the depth of the oil retaining groove varies depending on the size of the clubchi plate, but is approximately 0.08 to 0.5 mm, especially 0.10 to 0.5 mm.
Approximately 0.12 mm is preferable. In addition, the distance U between the oil retaining grooves varies depending on the size of the clutch plate, but is 1.0
The thickness is preferably about 10 mm, particularly about 2 to 5 mm. The sliding friction surface, which is the surface of the grooved clutch plate, has been flattened and rolled, so the difference between the height of the highest sliding surface and the height of the lowest sliding surface is almost 0, so the sliding friction surface is The cross section can be drawn in a straight line as shown in Figure 5.

的になりがちであり、作業能率の向上に限界があった。Now, in order to form an oil retaining groove with a tapered inner surface where the opposing distance decreases toward the back, it can also be done by pressing a steel plate with a press mold having protrusions. . However, when forming with strong pressure using a press mold, the pressing force tends to be large due to the surface contact between the steel plate and the mold surface of the press mold,
A press mold with an extremely large pressing force of 00 tons is required, and the installation cost is also high. Also, 2000-30
Even if a sliding friction surface is formed with a press die using an extremely large pressing force of 00 tons, the sliding friction surface will not flatten and swell upward due to the surface contact between the steel plate and the die surface of the press die. It tends to be. In addition, the steel plate must be removed from the press die after forming with the press die, and the work tends to be intermittent, which limits the improvement in work efficiency.

されやすい。In this regard, when forming the above-mentioned oil retaining grooves on the protrusions of the rolling roll, it is necessary to use a rolling roll [coal and the steel plate are not in surface contact but in a diagonal contact state, so it is necessary to No pressing force is required, and it is advantageous in reducing equipment costs. Further, since the rolling roll and the steel plate are in contact with each other in a diagonal contact state, the sliding friction surface can be easily flattened without using a large pressing force.
また、圧延ロールの回転によって行ないうるので連続的
に油保持溝を形成することができ、作業能率の向上を図
