<P>PROBLEM TO BE SOLVED: To provide a damper, in which sealability for oil having flowed into an accumulator can be enhanced. <P>SOLUTION: In this damper, fluid is allowed to flow into and out of a fluid chamber and to circulate in a cylinder C, and also a piston rod R is braked by fluid resistance. The side of the base end of a bladder 20 covers the whole end surface of a liner 10 on the side of the base end, and is formed with a rod sliding hole 24R through which the piston rod R penetrates. The inner peripheral surface of the rod sliding hole 24R is formed with an oil sealing portion 24b for sealing oil between the bladder 20 and the piston rod R, and a dust sealing portion 24a for sealing intrusion of dust into the cylinder C on the side of the base end of the oil sealing portion 24b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
