Inventors: Omata, Nobuaki;
Assignee: Nifco Inc. (Yokohama, JP)
Primary Examiner:

Attorney, Agent or Firm:
An oil type damper comprises a cylindrical wall formed integrally with a base secured on a given machine, a cap set in place rotatably within the cylindrical wall and integrated with a toothed wheel, a seal disk forming a housing in combination with the cap, and oil filling the interior of the housing. The integration of the toothed wheel and the cap decreases the number of component parts, reduces the time and labor involved in assembly, and permits size reduction of the damper. |

DETAILED DESCRIPTION What is claimed is: 1.
An oil type damper, comprising a blind cylindrical wall 15 formed integrally with a base having means 14 adapted to be secured to a given machine, a cap 11 set in place within said cylindrical wall 15 and retained rotatably therein, a seal disk 17 provided with a central hole, fixed integrally with said cap to cover the lower surface of said cap and adapted to form a housing in combination with said cap, and oil 18 filling the interior of said housing, said housing accommodating therein a stationary disk 16, said stationary disk being provided with a shaft 20 adapted to restrain the rotation of said stationary disk relative to the rotation of said cap, and said shaft being extended outwardly through a central hole in said seal disk and non-rotatably connected to said base.
2.
A damper according to claim 1, wherein said shaft 19 having a non-circular portion 20 for restraining the rotation of said stationary disk is formed integrally with said stationary disk 16.
3.
A damper according to claim 1, wherein said shaft 26 for restraining the rotation of said stationary disk 16 is formed independently of said stationary disk 16 and includes a non-circular portion 25 fitted into a complimentry hole of said stationary disk and connected thereto.
Description:
BACKGROUND OF THE INVENTION This invention relates to an oil type damper which relies on the viscosity of oil to brake the opening or closing motion of, for example, a lid in some type of machine.
In a cassette tape recorder or a video tape recorder, for example, there is used a damper for braking the sudden release motion of the lid of a cassette tape holder during the opening or closing of the tape holder for the purpose of abating impacts generated during the release motion.
The damper of this kind generally comprises a base adapted to be secured on the body of a given machine and a rotor accommodated rotatably within the base and adapted to receive the rotational opening or closing motion of a lid of a cassette holder, for instance
