摘要： PROBLEM TO BE SOLVED: To facilitate machining of a member with cam face parts needing accuracy to reduce cost by applying carburizing treatment or high frequency quenching only to the cam face parts in the member with the cam face parts receiving a rolling element, and molding the parts other than the cam face parts by forging or casting. SOLUTION: A variable long joint means which is cam mechanism in a multiple disk clutch is formed in such structure that a roller for generating reaction is interposed between a piston and a support member 10. At the time of manufacturing the support member 10 serving as a member with cam face parts 15, the cam face parts 15 are machined separately from a body having non-cam-face parts 12 and a cylindrical part 13 and connected later to the non-cam-face parts 12 with an adhesive or the like. The cam face parts 15 are formed in sector shape in the mutually connected state and formed in specified hardness by molding steel and applying carburizing treatment or high frequency quenching, while the body is formed as an injection-molded resin product or a cast aluminum product.

摘要： PROBLEM TO BE SOLVED: To make the mesh of filter medium fine and to contrive to reduce the number of parts, to simplify the structure and to improve the washing effect. SOLUTION: In an oil strainer for a solenoid valve connected to a hydraulic circuit in hydraulic control and for filtering a liquid, an oil strainer 10 has a filter medium 12 consisting of felt. Since the mesh of the felt is fine, the filterability of the impurities is improved. In this way, since by integrally forming the felt material, the oil strainer for the solenoid valve can be obtained, the material cost can be lowered. Further, since the manufacturing process can be simplified, the production efficiency can be raised.

摘要： PROBLEM TO BE SOLVED: To reduce the number of parts and to simplify the assembly in a one-way clutch. SOLUTION: A one-way chutch 40 is provided with a retainer 45 which holds a sprag 43 to be bitten between an outer ring 41 and an inner ring 42 by a holding hole 44, and is interposed between the outer ring and the inner ring. The retainer 45 is provided with an elliptical flange 47 to be pressure-contacted against an inner circumference of a spot facing hole formed concentrically with a side part of the outer ring 41. Because the retainer 45 holds the sprag by the holding hole 44, the structure of the one-way clutch is simplified. When the flange 47 is pressed into the spot facing hole in the outer ring 41, the long diameter part of the flange 47 presses the inner circumference of the spot facing hole to integrate the retainer 45 with the outer ring 41.

摘要： PURPOSE:To realize easy manufacturing and a low cost. CONSTITUTION:A spiral groove 8c is provided on the outer peripheral surface of the outer ring 8 of a one-way clutch, and is integrally formed at the time of forming the housing of a stator 5 to be integrated with the housing. Preferably the spiral direction of spiral is set in a direction where the one-way clutch is pushed to the abutting side surface of the housing when the one-way clutch is in a locked condition.

摘要： PURPOSE:To enable a transmission to suddenly switch to a reverse speed change shift, when an electric vehicle is desired to switch to reverse running, based on preventing a reverse drive by a one-way clutch. CONSTITUTION:When a motor 1 is driven, forward rotation of a shaft 3 is transmitted to a wheel through a clutch 5 and a transaxle 2, to an electric vehicle. Stopping is attained by only deenergizing the motor 1. When this stopping the vehicle is performed on an ascending road, reversing the vehicle can be prevented by a one-way clutch 6. Here with reversing desired, in order to place the transaxle 2 in a reverse speed change shift, when a manual clutch 5 is released, a transaxle input shaft 4 is placed in a freely rotatable condition, and the transaxle 2 can be switched to the reverse speed change shift from a forward speed change shift.

摘要： PURPOSE:To stably retain a holder and produce it at low cost without increasing the number of parts by executing the cut and bending work on the end face of the holder in the curved form and forming a guide face for an outer ring or an inner ring. CONSTITUTION:A holder 1 has a flange 5 formed on the right end face thereof to define guide faces 2 for the surface of an inner ring and has three cut-and- bent parts formed on the left end face to define guide faces 4 for the surface of the inner ring. The holder 1 is therefore maintained in a certain position by both the guide faces 2 of the flange part and the cut-and-bent parts so that the movement of the holder 1 is reduced extremely. Thus the dancing action of the holder 1 may be prevented so that the holder 1 may be kept in the stable position. Since the guide faces 2 are formed by the cut-and-bent procedure, the need for increasing the number of part may not be eliminated, the assembly is facilitated and no cost is increased.

摘要： PURPOSE:To obtain a one-way clutch bearing with long service life by a structure wherein the relative pivoting movement in one direction between an inner ring and an outer ring is prevented and consequently the torque is transmitted by the displacement of rolling elements in a groove formed on the inner surface of the outer ring or the outer surface of the inner ring. CONSTITUTION:A retaining means 40 of plug 30 is arranged in an annular space 14 between an outer ring 10 and an inner ring 20. The retaining means 40 consists of an annular first retaining member 42 arranged on the outer ring 10 side, an annular second retaining member 44 arranged on the inner ring 20 side and an annular energizing spring 46 arranged between the retaining members 42 and 44. In addition, rectangular holes are provided at equal intervals along the respective peripheries on the first retaining member 42, the second retaining member 44 and the energizing spring 46 in order for the plug 30 to hold therein.
