摘要： A damper includes a cylinder, a piston, a piston rod, a rod-side fluid chamber, a piston-side fluid chamber, an annular fluid chamber, and a stopper mechanism. The cylinder includes an inner tube and an outer tube. The rod-side fluid chamber is defined by the piston in the inner tube on a lower end side. The piston-side fluid chamber is defined by the piston in the inner tube on an upper end side. The annular fluid chamber is between the inner and outer tubes. At least one communication hole communicates the rod-side fluid chamber with the annular fluid chamber. A communication passage communicates the rod-side fluid chamber with the annular fluid chamber. A check valve in the communication passage allows fluid to flow from the annular fluid chamber to the rod-side fluid chamber and disallows the fluid to flow from the rod-side fluid chamber to the annular fluid chamber.

摘要： An air spring structure has a first communication hole formed in a peripheral surface of a cylinder and a second communication hole formed in the peripheral surface at a position closer to an axle than the first communication hole. A piston has a sliding portion that comes into contact with an inner peripheral surface of the cylinder and partitions the cylinder into an inner chamber and a balance chamber. The sliding portion has an axial length shorter than an axial length between the first communication hole and the second communication hole. A communication member has a communication path formed so as to pass through the first communication hole and the second communication hole to allow the inner chamber and the balance chamber to communicate with each other.
