Abstract:
1. A process of forming a damper, the damper being a fitting type including a hub, an inertial mass body, and a polymer elastic body press-fitted between the hub and the inertia mass body from an axis direction thereof, wherein a surface roughness in at least one of a metal surface adhering to the polymer elastic body in the hub and a metal surface adhering to the polymer elastic surface in the inertia mass body is within a range of 15 to 50 μmRz, the process comprising: a first step of applying an organosilane solution as a non-slip agent onto at least one of both surfaces of said hub and said inertia mass body, both surfaces facing the polymer elastic body; a second step of press-fitting the polymer elastic body applied onto the organosilane solution between the hub and the inertia mass body; and a third step of heating the damper to remove a solvent thereof, reacting the organosilane in the surface of said polymer elastic body and at least one of both surfaces of said hub and said inertia mass body, and attaching and fitting said hub and said inertia mass body.
