PURPOSE: A multi-stage shock absorbing damper is provided to rapidly close a door by rapidly moving a shaft using first and second shock absorbing parts. CONSTITUTION: A multi-stage shock absorbing damper comprises a cylinder housing(10), a shaft(30), and a fluid resistor(70). One end of the cylinder housing is opened, and the cylinder housing has a hole filled with fluid. The cylinder housing has first and second shock absorbing parts(15,17). The shaft is inserted into the cylinder housing and can be drawn out of the housing using an elastic support(20). The fluid resistor transfers the resistance of the filled fluid to the shaft by controlling the flow of the fluid. |
