no. 2 approach
[0063] In the above-described first embodiment, the hysteresis characteristic due to the sliding contact between the thrust member 10 and the thrust member 11 , which are the first sliding contact members, and the flange portion 2 b of the hub member 2 is obtained. Also in this case, the obtained hysteresis characteristic can be made variable. Hereinafter, this second embodiment will be described in detail, but the same parts as those in the above-mentioned first embodiment will be assigned the same reference numerals and their descriptions will be omitted.
[0064] Such as Figure 4 and Figure 5 As shown, compared with the device 1 in the above-mentioned first embodiment, the control board 21, the control board 22, the thrust member 23, the disc spring 24, the thrust member 25, and the pin member 26 are provided in the second embodiment.
[0065] The control plate 21 is disposed between the flange portion 2 b of the hub member 2 and the thrust member 10 on the side of the ...
no. 3 approach
[0075] Such as figure 1 and figure 2As shown, in the device 1 of the above-mentioned first embodiment, the thrust member 10 that is the first sliding contact member is provided with a cylindrical anti-rotation portion 10a that is concave and convex along the circumferential direction of the rotation axis J. The inner peripheral portion 3 a of the disk plate 3 , which is a profile plate, is engaged with the rotation stop portion 10 a. Thus, the rotation of the thrust member 10 is blocked by the disk plate 3, and when the hub member 2 rotates integrally with the input shaft S and relative rotation occurs between the thrust member 10 and the flange portion 2b, the thrust member 10 and the flange portion There is friction between 2b.
[0076] However, the size of the outer diameter of the large-diameter portion 10 c of the thrust member 10 is larger than the size of the inner diameter of the inner peripheral portion 51 a of the first plate 51 of the intermediate plate 5 . Ther...
no. 4 approach
[0091] In the third embodiment described above, the thrust member 30 , which is the third sliding contact member, is fixed so as not to rotate relative to the flange portion 2 b of the hub member 2 via the rotation stopper 30 a. Here, similar to the above-mentioned second embodiment, the control board 21, the control board 22, the thrust member 23, the disc spring 24, the thrust member 25, and the pin member 26 can also be provided in the present device 1 of the above-mentioned third embodiment. Make the hysteresis characteristic variable.
[0092] In this case, if Figure 9 and Figure 10 As shown, the control board 21 , the thrust member 23 and the disc spring 24 are provided between the flange portion 2 b of the hub member 2 and the thrust member 30 as in the case of the above-mentioned second embodiment. Furthermore, as described in the above-mentioned second embodiment, the control plate 21 is fixed to the flange portion 2b of the hub member 2 so as to be integrally rot...
