VIBRATION ISOLATING DEVICE

摘要

PURPOSE:To prevent the transmission of vibration, by connecting the piston rod of the attenuator of a device whose air chamber is formed of a bottomed cylindrical component and a cylindrical flexible membrane above the telescopic attenuator with the bottomed cylindrical component through an elastic member. CONSTITUTION:An air chamber 4 is formed of a bottomed cylindrical component 2 surrounding the piston rod 1b of a telescopic attenuator 1 and a cylindrical flexible membrane 3 whose one end is connected with the bottomed cylindrical component and the other end is connected with a cylinder 1a respectively. As the piston rod 1b is connected with the inside of a contracted diametrical part 2c of the bottomed cylindrical component 2 through an elastic member 11, transmission of oscillation is being prevented by allowing a relative movement in the axial direction of the piston rod 1b. A fixing bracket 13 is connected with the external circumference of the contracted diametral part 2c through a buffer member 12 and the transmission of the oscillation to a vehicular body side is prevented.
