Abstract

The present invention relates to a damper, and more particularly, to a rotary-type oil damper that can damp a rotating force, which is generated when a door and a cover or lid are opened and closed, by using a blade rotating along a rotation axis and a flow resistance of a viscous fluid. The rotary-type oil damper includes a blade positioned in an airtight space, the airtight space being filled with a viscous fluid, a rotation axis being connected to an object for damping a rotating force and rotating the blade, and a first flow path being formed on the rotation axis so as to connect spaces divided by the blade, and having different cross-sections exposed to the divided spaces based upon rotating movements of the rotating axis.
