Claims

[Claims for Utility Model Registration] A mounting base made of plastic; a rotary damper fixed to the mounting base and having an input gear; and an intermediate gear made of plastic that is fixed to the mounting base and meshes with the input gear of the rotary damper. The mounting base is provided with a hollow rib into which the intermediate gear is fitted, and the inner edge of the opening of the rib is formed with a tapered surface whose diameter decreases toward the hollow part. A plastic pin for preventing the intermediate gear from coming out is press-fitted into the rib from the opening toward the hollow part, and the pin has a shaft part with a diameter larger than the inner diameter of the hollow part of the rib, and a plastic pin to prevent the intermediate gear from coming out. It is characterized by integrally comprising a large-diameter head projecting from the end of the shaft, and a tapered part having an outer diameter approximately equal to the inner diameter of the hollow part of the rib is formed at the tip of the shaft. Rotating damper device.
