するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a one-way clutch used in starting devices for automobiles, motorcycles, etc., power transmission devices for various industrial machines, and the like.
一方向クラッチは、順方向回転時にのみトルクを伝達す
る機能を有するクラッチで、近年における各種産業機械
の省力化、高速化、高能率化への発展に伴って、その利
用分野も広くなり、重要な機械要素となっている。A one-way clutch is a clutch that has the function of transmitting torque only when rotating in the forward direction.In recent years, with the development of various industrial machinery to become labor-saving, faster, and more efficient, its application fields have expanded and become important. It is a mechanical element.

部材間にくさび状の空間を形成し、この空間に保持した
転動体を介して前記回転軸と回転部材とを連結するよう
に構成されている。A typical one-way clutch is one that includes a clutch body connected to a rotating shaft and a rotating member, with a wedge-shaped space formed between these members, and a rolling element held in this space. The rotation shaft and the rotation member are configured to be connected to each other.

たものである。Incidentally, since the clutch body is required to have strength, conventionally, the space for holding the rolling elements and the cam surface are formed by processing a high-strength material. For this reason, when machining the clutch body, a time-consuming cutting process is required. In response to this, the present applicant has proposed Japanese Patent Application No. 132596/1983 (1 invention title: ``one-way clutch''). This separates the clutch body into a plate part that requires strength and a housing part that does not require strength, provides a concave part in the housing part to hold the rolling element, and bends the tongue part where the rolling element engages with the plate part. It was formed.
しかしながら、従来のこの種一方向クラッチにおいては
、舌片部を屈曲形成することでプレート部にカムを設け
ているので、カムの強度を得るためにプレート部および
舌片部をを比較的厚く形成する必要があり、重量が大き
くなるという不都合があった。However, in conventional one-way clutches of this kind, the cam is provided in the plate part by bending the tongue part, so the plate part and the tongue part are made relatively thick in order to obtain the strength of the cam. This has the disadvantage of increasing weight.
本発明はこのような事情に鑑みなされたもので、重量を

形成したものである。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a one-way clutch that can be reduced in weight. In the one-way clutch according to the present invention, the clutch body is composed of a plate portion provided with a cam portion with which the rolling elements engage, and a housing portion fixed on the plate portion and holding the rolling elements together with the cam portion. The cam portion is formed into an annular shape.

This cam portion 8 has a plurality of cam surfaces 10 facing the outer peripheral surface of the rotating member 3 and with which rollers 9 as rolling elements engage. A roller 9 is held between the rotating member 3 and the rotating member 3. In this embodiment, the plate portion 4 is formed from a sheet metal material pressed into a substantially triangular shape. The cam portion 8 is formed into an annular shape and integrally with the plate portion 4 by drawing the peripheral edge of this sheet metal workpiece into a substantially triangular shape. In other words, the cam portion 8 is erected integrally with the plate portion 4 so as to have a cross-sectional shape. Three cam surfaces 10 are formed on the inner surface of the cam portion 8 at equal intervals in the circumferential direction, and are inclined so as to gradually approach the outer circumferential surface of the rotating member 8 in the rotation direction of the rotating member 30. In this drawing process, the corner 10a of the cam surface 10 is recessed in an arc shape to ensure engagement with the roller 9.

。In addition, since the cam part 8 is formed in an annular shape, the load acting on the cam surface 10 in the direction of arrow B during the operation of the one-way crofch is transmitted not only to the corners of the cam surface 10 but also to both sides. Can receive. In other words, the lever disperses the stress that was previously concentrated on a part of the cam. Therefore, it is possible to receive a larger load than in the conventional case where the load acts as a moment on only a portion of the cam surface.

かられている。As described above, the present invention improves the strength of the cam surface 100 by forming the cam part 8 provided on the plate part 4 into an annular shape. 4 into a substantially triangular shape. For example, as shown in FIG. 5 as a perspective view of the main part, and as shown in FIG. 6 as a cross-sectional view of the main part, a bottomed cylindrical sheet metal workpiece 30 may be formed by drawing. That is, in this embodiment, the axially central portion of the outer peripheral surface of the sheet metal workpiece 30 is recessed in the inner diameter direction to form the cam surface 10. For this reason, the cam portion 8 is formed with an edge portion 31 bent in a cross-sectional shape, and this bent portion is intended to improve the strength.
