イブシャフト、プロペラシャフト等に装着される。As shown in FIG. 3, in a conventional torsional damper, an inertia ring 4 is attached to a plate 2 fixed to a rotating shaft 1 via rubber 3.3, and a gap 1 is maintained between these three members.
00 was formed, and the viscous fluid 5 was sealed in this gap 100. The inertia ring 4 is divided into two pieces 4A, 4.
It consists of B. The overlapping portions of the divided pieces 4A and 4B are welded. Alternatively, as shown in FIG. 4, the thin piece portion 4A' on the side of the divided piece 4A was caulked and integrated with the divided piece 4B. The torsional damper, in which the gap 100 is formed and the viscous fluid 5 is sealed in the gap 100, is used for crankshafts of high-performance engines that are lighter in weight and have an expanded rotational range in order to achieve higher speeds and higher outputs. It is installed on crankshafts, drive shafts, propeller shafts, etc. to suppress torsional vibration and westward vibration of the system and reduce noise.

うためにゴ１．３と慣性リング４との接着力は弱く、使
用中に接着部の剥離を起こし易いものであった。In the conventional torsional damper, the rubber 3 is first vulcanized and bonded to the plate 2 to bond the rubber 1.3 to the inertia ring 4 and the plate 2 to the rubber 3. Next, the inertia ring 4 is set, and the inertia ring 4 is again bonded to the inertia ring 3 mainly with an adhesive. Since the casing for enclosing the viscous fluid 5 was created by welding or caulking the overlapping parts of the divided pieces 4A and 4B, the adhesive force between the gong 1.3 and the inertia ring 4 was It was weak and the adhesive part was likely to peel off during use.

悪影響を与えることもなくなる。In FIG. 1, a rotating shaft 1 is not shown, but as shown in FIG. 3, a similar rotating shaft 1 is present, and a plate 2 is fixed to this rotating shaft 1. The inertia ring 4 attached to the plate 2 via the rubber 3 includes an adhesive part 4C9°4D including a part to be adhered to the rubber 3, and other parts 4C=
, 4D2. The adhesive parts 4C, 4D are vulcanized and adhered to rubber. Of course, both Go 1.3 and Plate 2 are vulcanized and bonded. I wanted to-C, plate 2.
Rubber 3. The adhesive parts 4C, 4D are strongly integrated. Next, other parts 4C2, 4D2 are welded to the adhesive parts 4C, 4D, and finally other parts 4C2
and 4D2, and as shown in FIG. Rubber 3. A gap 100 is formed between the three members of the inertia ring 4, and a viscous fluid 5 similar to the conventional one is sealed in this gap 100. Adhesive parts 4C, 4D, and other parts 4C2, 4D
It is preferable to use laser welding or electron beam welding for welding with 2. If laser welding or electron beam welding is performed, the influence of heat is very small, so that the rubber 3 will not be adversely affected by heat.

ない。Note that electron beam welding has some difficulty in mass production because it is necessary to create a vacuum atmosphere in the workpiece. Laser welding and electronic beat welding have higher energy density than other welding methods.
It can irradiate a large amount of energy in a small area. Therefore, the range in which the temperature rises is narrow, and the effect on rubber etc. is small.

Although the overlapping portion with 4D was welded, it is also possible to integrate both parts by caulking as shown in FIG. Further, the design can be changed as appropriate as to where the boundary between the adhesive parts 4C+, 4D and the other parts 4C, 4D2, that is, where the dividing line should be drawn. Adhesive parts 4C, 4D,
should include at least the part that is bonded to the rubber.
