A large frictional force is applied to the sliding surface on the turbine hub 15 side of the retainer 9, which is generally made of aluminum.
There was a problem with severe wear. Another problem was that the worn retainer 9 turned into powder and mixed into the hydraulic oil, which adversely affected the hydraulic system.

は鋳鉄製としてもよい。(Embodiment) In FIGS. 1 to 4 showing an embodiment of the present invention, 20 is a substantially ring-shaped sliding member, and this sliding member 20 has a surface that contacts the turbine hub 15. For example, three oil grooves 21 having a V-shaped cross section are formed radially on the outer peripheral surface 20a, and rectangular engaging protrusions 22 are formed at predetermined locations (for example, three locations radially) on the outer peripheral surface 20a. . The sliding member 20 is made of a wear-resistant material, such as LBC (lead bronze casting), PBP (phosphor bronze plate), or wear-resistant resin.
24 is a retainer body, and this retainer body 2
4 has three recesses 25 radially forming oil passages 16 between it and the sliding member 20, and the inner circumferential surface 26a of the recess 25 forms an oil passage 16 between the sliding member 20 and the outer circumferential surface 2 of the sliding member 20.
A substantially ring-shaped protrusion 26 is formed to fit into the hole 0a. A recess 27 that fits into the engagement projection 22 of the sliding member 20 is provided at a predetermined location of the ring-shaped projection 26.
Also, an oil passage recess 28 is formed to prevent the radial recess 25 forming the oil passage 16 from being blocked.
As for the material of the retainer body 24, there is no need to use expensive LBC or PBP that has wear resistance. For example, aluminum, which can be manufactured at low cost and has been conventionally used for the retainer 9, may be used, or it may be made of cast iron. .

4 to construct a retainer, the outer peripheral surface 20a of the sliding member 20 is fitted into the inner peripheral surface 26a of the ring-shaped projection 26, and the engaging projection 22 is fitted into the recess 27 of the ring-shaped projection 26. It is only necessary to integrate the sliding side member 20 and the retainer body 24 by doing so.

る必要がなく経済的である。(Effect of the invention) The retainer of the fluid torque converter according to the invention includes a substantially ring-shaped sliding member 20 formed of a wear-resistant member and provided with a radial oil groove 21 and an engaging protrusion 22; A radial recess 25 that forms an oil passage 16 with the moving side member 20 and a substantially ring-shaped protrusion that fits into the outer peripheral surface 20a of the sliding side member 20 and has a recess 27 at a location corresponding to the engagement protrusion 22. 26, the engaging protrusion 22 fits into the recess 27, and the outer peripheral surface 20a of the sliding member 20 has a ring-shaped protrusion 2.
Since the sliding side member 20 and the retainer body 24 are integrally formed by fitting into the inner circumferential surface 26a of the retainer 6, the sliding surface with the turbine hub 15 is sufficiently supplied with oil from the oil groove 21. Wear of the sliding side member 20 can be suppressed, and since the sliding side member 20 is made of a wear-resistant material, the sliding side member 20 can be prevented from being worn out. Since 24 can be formed from an inexpensive member, the cost of the retainer body can be considerably reduced. Furthermore, the axial dimension of the retainer can be made shorter than when a thrust needle bearing is used. Furthermore, when the sliding member 20 is worn out, only the sliding member 20 can be replaced, which is economical since there is no need to replace the entire retainer.
