Claims

[Scope of utility model registration request]

To cancel the unbalanced inertia of the crankshaft, the rotating member is attached via a coupling means to a rotating member that is rotated in conjunction with the crankshaft and has a parallax that rotates together with the rotary member to cancel the unbalanced inertia of the crankshaft. In the device, the coupling means includes an inner race having an outer tapered surface on its outer surface, an outer L north having an inner tapered surface on its inner surface,
It is inserted between the outer tapered surface and the inner tapered surface of the inner race and outer race, which are arranged concentrically, and is moved by a tightening port to tighten the inner north and outer race in their radial direction. A crankshaft imbalance characterized by comprising a plurality of suppression rings that integrally connect one rotating member inserted into the inner race and the other rotating member inserted with the outer race pressed against each other. Inertial force canceling device.
