Embodiments of this invention will be described below with reference to FIGS. 1 to 4. Note that the same parts as those of the conventional example shown in FIGS. 5 and 6 described above are designated by the same reference numerals, and the explanation thereof will be omitted.
図示のように、一対の軌道輪１，１′のうち、
一方の軌道輪１は薄肉厚の金属板から成り、この
金属板のプレス成形によつて片面の外周部に他方
の軌道輪１′を外嵌する案内筒４を設け、かつも
う一方の面の中央部に支持筒７を形成してある。 As shown in the figure, among the pair of bearing rings 1 and 1',
One of the bearing rings 1 is made of a thin metal plate, and by press forming this metal plate, a guide tube 4 into which the other bearing ring 1' is fitted is provided on the outer periphery of one side. A support tube 7 is formed in the center.
上記案内筒４の開口縁８は、他方軌道輪１′の
外側面を含む平面にほぼ一致し、その開口縁８か
ら案内筒４の延長方向に複数の突片９を設け、各
突片９に他方軌道輪１′の外周部に対向する突起
５を形成してある。 The opening edge 8 of the guide tube 4 substantially coincides with a plane including the outer surface of the other bearing ring 1', and a plurality of projecting pieces 9 are provided in the extending direction of the guide tube 4 from the opening edge 8. A protrusion 5 is formed opposite to the outer circumference of the other bearing ring 1'.
上記突起５は、他方軌道輪１′の組み込み後に

ている。また、他方の軌道輪１′を突起５の形成
後に組み込むため、突片９の数を必要以上に多く
すると、軌道輪１′の組み込みが不可能になる。
このため、実施例においては、案内筒４の開口縁
８の三等分位置に突片９を設けてあるが、開口縁
８の二等分位置に設けるようにしてもよい。 The protrusion 5 may be formed after the other raceway ring 1' is assembled, but if it is formed after the assembly, the protrusion 9 may be deformed and the roundness of the guide tube 4 may be affected. is protrusion 5
After the formation of the bearing ring 1', the other bearing ring 1' is assembled. Further, since the other raceway ring 1' is assembled after the projections 5 are formed, if the number of protrusions 9 is increased more than necessary, it becomes impossible to incorporate the raceway ring 1'.
For this reason, in the embodiment, the protrusions 9 are provided at three equal parts of the opening edge 8 of the guide tube 4, but they may be provided at two equal parts of the opening edge 8.
なお、他方の軌道輪１′の組み込みにおいては、
その軌道輪１′の一部分を案内筒４の内側に挿入

の背部に軌道輪１′の嵌合部分を位置せしめ、非
嵌合部分を叩打する方法等によつて残る突片９の
突起５の内側を無理矢理通過させる。 In addition, when assembling the other bearing ring 1',
A part of the bearing ring 1' is inserted inside the guide cylinder 4, and the projections 5 of two of the three projections 9 are inserted.
The fitting portion of the bearing ring 1' is positioned on the back of the bearing ring 1', and the non-fitting portion is forced to pass through the inside of the protrusion 5 of the projecting piece 9 remaining by tapping or the like.
突片９に形成する突起５の数は任意であるが、
軌道輪１，１′は焼入れによつて硬度を高めてあ

起５は、複数設けるのが好ましいが、必要以上に
突起５を設けると、他方軌道輪１′の組み込みが
困難になる。 The number of protrusions 5 formed on the protrusion piece 9 is arbitrary, but
Since the bearing rings 1, 1' have been hardened to increase their hardness, if the number of protrusions 5 is one, there is a problem in terms of strength, and there is also a risk of chipping when the bearing ring 1' is assembled. Therefore, it is preferable to provide a plurality of the projections 5, but if more projections 5 than necessary are provided, it becomes difficult to assemble the other raceway ring 1'.
そこで、実施例においては、三つの突片９のう

As described above, in this invention, a protrusion is provided on the opening edge of the guide tube provided on one raceway, and a protrusion is formed on the protrusion, so that the other raceway fitted inside the guide tube can be prevented from coming off by the above-mentioned protrusion, and the above-mentioned opening edge is made substantially coincident with the plane containing the outer surface of the other raceway ring.
Disadvantage that when assembled between the torque converter pump and the load support member, the radial oil passage formed between the load support member and the other bearing ring is blocked by the opening edge of the guide tube. There is no oil flow to the converter, and the flow of oil to the converter is smooth.
