Title: Power unit damper
Inventor: IDE TAKANOBU
IPC: F16F9/12
Filed: 1989-12-20
Abstract: PURPOSE:To prevent the sealing ability of a viscous fluid from lowering when temperature rises in a power unit damper using viscous shearing resistance by using synthetic resin, having a larger coefficient of linear expansion than metallic material, for a material for a casing accomodating the disc of the metallic material. CONSTITUTION:In a power unit damper A using viscous shearing resistance, the material for a casing 11 for accomodating a disc 10 made of metallic material having a designated coefficient of linear expansion is synthetic resin having a larger coefficient of linear expansion than the above metallic material. Accordingly, when temperature rises, a viscous fluid 12 such as silicone oil or the like filled in a gap is expanded by a difference in coefficient of linear expansion between both materials, whereby the gap for sealing the fluid is expanded. Thus, sealing ability can be prevented from lowering without any increase in the internal pressure in the casing 11.
