Viscous fluid-filled damper and mounting structure for viscous fluid-filled damper

摘要

Obtained is a viscous fluid-filled damper which makes it easy to determine whether or not a shaft or the like protruding from a supporting body side or a supported body side has been sufficiently inserted therein and which can be easily mounted on a supporting body or a supported body, and a mounting structure thereof. In the viscous fluid-filled damper, a shaft mounting portion (32) of the viscous fluid-filled damper (31) for damping vibrations between the supporting body and the supported body is provided with a shaft receiving hole (32a) for receiving the shaft, and a window hole intersecting the shaft receiving hole (32a) and having a hole port opening to a lateral surface of the shaft mounting portion (32). Therefore, it is easy to determine whether or not the shaft has been inserted correctly, and a large force for retaining the shaft is ensured.
