PURPOSE:To make viscous oil flow forcedly inside the main body of a damper and thereby to realize an efficient vibration-damping action, by sealing up the viscous oil inside the main body by means of a rubber tube arranged at a circular opening made inside the main body, and by pressing the rubber tube by the vibration of a vibrating body through the intermediary of a disc. CONSTITUTION:The main body 1 of a damper is formed to be a circular body constituted by a channel opened inside, and edges 1a bent inside are provided at the end of the opening. Inside the main body 1 of the damper, a rubber tube 2 is arranged with both ends engaged with said bent edges 1a so as to seal up a viscous oil filled up inside the main body 1. Moreover, a rod 4 is inserted into the rubber tube 2 at its center. The rod 4 supports a vibrating body V at the upper end, while a disc 5 fixed to the lower end thereof presses the rubber tube 2 radially. By this constitution, the viscous oil can be made to flow forcibly inside the main body 1 of the damper in whichever direction the disc 5 presses the rubber tube 2 under the vibration of the vibrating body V, and the viscous resistance of the oil enables the realization of a strong vibration-damping action. |
