A damper 100 is provided with: a cylinder 10 in which an operating fluid is sealed; a piston 20 disposed in a slidable manner within the cylinder 10; and a piston rod 21 connected to the piston 20. The piston 20 has: a main flow passage 22 which provides communication between a pair of fluid chambers 11, 12, allows an operating fluid to flow therethrough when the piston 20 moves, and provides resistance to an operating fluid flowing therethrough; a bypass flow passage 23 provided parallel to the main flow passage 22 and providing communication between the pair of fluid chambers 11, 12; and a temperature compensation section 60, 260 which is inserted in the bypass flow passage 23 and which, according to the temperature of an operating fluid, deforms in the direction perpendicular to the bypass flow passage 23, thereby changing the flow passage area of the bypass flow passage 23. |
