a lower space a communicating hole not shown in the drawing can be provided to the piston 115 to enable the upper and lower spaces to communicate with each other optionally another communicating hole not shown in the drawing can be provided to the cylinder 113 to enable the upper and lower spaces to communicate with an external environment optionally the internal space of the cylinder 11 can be filled with such liquid as oil and the like fluid such as air and the like within the internal space of the cylinder 113 performs damping and shock absorbing together with the friction ring 114 the piston rod 110 is guided by a guide part 112 formed of a plastic based material on the cylinder 113 a hole is provided to an upper part of the piston rod 110 to enable a hinge pin 134 to be inserted therein and a rubber bushing 111 is fitted into the hole meanwhile the damper is connected to the cabinet base 70 via a shock absorbing member such as a rubber bushing 118 shown in fig5 a bracket 71 is assembled to a circumference of the rubber bushing 118 and fixed to the cabinet base 70 as well a passing hole is formed in the rubber bushing 118 and a connecting part.
