Abstract

PURPOSE:To enable external operational control of a free piston to extract mixed air in hydraulic oil and supply the hydraulic oil in a hydraulic damper provided with a cylinder partitioned inside by the free piston into an oil chamber and a bottom gas chamber. CONSTITUTION:In a hydraulic damper for an autocycle, hydraulic oil pressurized by the compression work of an unillustrated main cylinder during a compression stroke is introduced into an oil chamber R3 of a subcylinder 20 via a connecting hose and compresses sealed-up gas in a gas chamber G to generate a pressure- damping force. At this stage, a free piston 50 partitioning the subcylinder 20 into the oil chamber R3 and the gas chamber G is composed of a piston main body 51, a rubber ball 52 acting as a plug, and a leaf spring 53. The leaf spring 53 is bent to form such a contiguration as allowing the rubber ball 52 to be hermetically fitted to a connecting hole 51a at the central bent area. This free piston 50 is operated by an operating jig 70 including a push rod 74 inserted through a setting hole 20a of a plug 21.
