PROBLEM TO BE SOLVED: To provide a viscous fluid enclosing damper by which a disk device in which a mechanical chassis having reproducing mechanism of disk media is incorporated is miniaturized further. SOLUTION: An edge damper 10 is formed by projecting a supporting concave part 12c in a closed container 11 in which a corner part 7b of a mechanical chassis 7 is inserted and housed in a flexible part 12 consisting of thermoplastic elastomer constituting a closed case 11. Excessive distortion deformation is not caused by receiving corner part 7b by a plane of the supporting part 12c and supporting by internal pressure of the viscous fluid 3 even if a coil spring for supporting mechanical chassis utilized conventionally is abolished. Also, excellent vibration damping effects are obtained by enclosing the viscous fluid 3 such as silicone oil or the like for damping the vibration of the mechanical chassis 7 in the closed container 11 and enabling that the supporting concave part 12c receiving the vibrations of the mechanical chassis 7 can stir the viscous fluid 3.
