摘要： A damper includes a cylinder, an annular rod guide, a rod, an annular oil seal, and an annular seal holder. The cylinder internally forms an action chamber. The rod guide is secured to one side opening of the cylinder. The rod is inserted through an inner peripheral side of the rod guide so as to be axially movable. The oil seal is installed to the action chamber side of the rod guide to be slidably in contact with an outer peripheral surface of the rod. The seal holder supports the oil seal from the action chamber side. The rod guide includes a holding portion to hold the seal holder.

摘要： A damper includes a cylinder, an annular rod guide, an annular seat, a rod, an annular oil seal, a rebound cushion, and a communication passage. The cylinder houses an action chamber. The rod guide is secured to one side opening of the cylinder. The seat is secured to the rod guide. The rod is inserted through inner peripheral sides of the rod guide and the seat. The oil seal is held to an inner periphery of the rod guide and slidably in contact with an outer peripheral surface of the rod. The rebound cushion bumps against the seat. The communication passage transmits a pressure in the action chamber to the oil seal. An opening on the communication passage on the action chamber side is disposed on an outer peripheral side relative to a part of the seat against which the rebound cushion bumps.
