PROBLEM TO BE SOLVED: To provide a miniaturized damper gear capable of executing stable braking performance, equipment using this damper gear, and a manufacturing method of the damper gear. SOLUTION: The damper gear comprises a storing body 11 for storing viscous fluid 14 inside, a brake body 12 rotatably supported in this storing body 11, and a rotating shaft 13 connected to the brake body 12 and extending outside the storing body 11. The storing body 11 is provided with a first hole 111E for passing the rotating shaft 13 and a second hole 112E for making part of the viscous fluid 14 flow out when the viscous fluid 14 is filled into the storing body 11. Therefore, air bubble mixing in with the viscous fluid 14 is discharged from the second hole 112E, and amount of air bubble in the viscous fluid 14 is largely reduced. Therefore, viscous resistance of the viscous fluid 14 can be stably exerted, and stable braking performance having no dispersion can be obtained. COPYRIGHT: (C)2005,JPO&NCIPI
