本考案は遠心クラツチに関し、詳しくはクラツ
チ内に支承されたクラツチウエイトの振動を抑止
するようにした遠心クラツチの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a centrifugal clutch, and more particularly to an improvement in a centrifugal clutch that suppresses vibration of a clutch weight supported within the clutch.

している。 Conventionally, in the case of a centrifugal clutch, especially an automatic centrifugal shift type clutch 1 as shown in the cross-sectional view of FIG. This is accomplished by bringing the shoe 3 into contact with the inner circumferential surface 4a of the housing 4, and by the frictional force between the clutch drive shoe 3 and the housing 4 when they come into contact, they are integrated. In the case of such a clutch 1, in particular, the clutch drive shoe 3 is attached to the inner circumferential surface 4a of the housing 4.
When the clutch plate 5 supports the clutch drive shoe 3, the rigidity of the housing 4 and the surface roughness of its inner circumferential surface 4a, the rigidity of the drive shaft 2, etc. Therefore, there was a risk that the transmitted torque would fluctuate. Therefore, conventionally, in order to suppress the vibration of the clutch drive shoe 3 when the clutch is connected, one end surface 3a of the drive shoe 3 is constantly pressed by a disc spring 7 via a plate 6. .

行なつている。 By the way, the above-described positioning of the disc spring 7 is achieved by attaching a retaining ring 9 to one end of the boss portion 8 that supports the clutch plate 5.
This is accomplished by fitting a circlip into the retaining ring 9 and engaging the inner circumferential edge 7a of the disc spring 7 with the retaining ring 9.

して前記駆動軸2に回動自在に支承されている。 Therefore, according to the conventional centrifugal clutch structure described above, in order to position the disc spring 7, a retaining ring 9 must be used and the retaining ring 9 must be fitted to one end of the boss portion 8, which requires a large number of parts. Moreover, since a space is required to fit the retaining ring 9 into the boss portion 8, the clutch becomes larger (the first
(It protrudes to the right in the figure) and also has the disadvantage that the assembly process is complicated. In FIG. 1, reference numeral 10 is a return spring, 11 is a key for fixing the boss portion 8 to the drive shaft 2, 12 is a washer, 13 is a nut, and 14 is a gear that rotates integrally with the housing 4. The gear 14 is rotatably supported on the drive shaft 2 via a bush 15.

させるようにしたものである。 In view of the above-mentioned drawbacks of the conventional centrifugal clutch, the present invention aims to provide a centrifugal clutch that reduces the number of parts, is compact, and simplifies the assembly process. The inner circumferential edge of a disc spring that presses a clutch weight is engaged with a nut that fixes a boss portion to a drive shaft.
以下、本考案に係る遠心クラツチの一実施例を
詳述する。 Hereinafter, one embodiment of the centrifugal clutch according to the present invention will be described in detail.

である。 In FIG. 2, a boss portion 20 supporting the clutch plate 5 is shown.
The width W 1 of the boss portion 8 is shorter than the width W 2 of the boss portion 8 shown in FIG. Further, a washer 21 is fitted onto the drive shaft 2 in contact with an end 20a of the boss portion 20, and a nut 22 is screwed into a threaded portion 2a formed at the end of the drive shaft 2.
2, the boss portion 2 is attached via the washer 21.
0 is tightened and fixed to the drive shaft 2. A protrusion 22b that protrudes radially outward from the cylindrical portion 22a is provided at one end of the nut 22, and a stepped portion 22c formed by the protrusion 22b and the cylindrical portion 22a is provided with a disc spring 7.
The inner circumferential edge 7a of the disc spring 7 is engaged with the disc spring 7, and the disc spring 7 is positioned there. Further, the cylindrical portion 22a of the nut 22
The inner circumferential edge of a plate 6 that regulates vibration of the clutch weight 3 is fitted into the inner circumferential edge of the plate 6 . In addition, the code|symbol 23 is a washer between the inner peripheral edge 7a of the disc spring 7 and the step part 22c.

図ることも出来る。 As described above, in positioning the disc spring that suppresses vibration of the clutch weight in a centrifugal clutch, the disc spring is engaged with a nut that tightens and fixes the boss portion of the clutch without using a retaining ring. This makes it possible to reduce the number of parts and simplify the assembly process.Furthermore, there is no need to provide space for attaching a retaining ring on the boss of the clutch, which is required in the past, making the clutch more compact. It is also possible to aim for
