を特徴とするダイクツシヨン装置のダンパ装置。 A cushion piston is arranged vertically movably inside each of the cushion cylinders, which are partitioned by partition members to form multiple upper and lower stages, and compress the air in the cushion cylinders by these cushion pistons to generate a cushion force. In the ductition device in which oil is generated, oil is put into the bottom of the air-action chamber of the cushion cylinder above the partition member, and between the partition member and the cushion piston of the cushion cylinder below the partition member. A damper piston is arranged to be movable up and down, and the upper part of the damper piston is a hydraulic damper chamber, and between the bottom of the air action chamber containing the oil and this hydraulic damper chamber, the oil at the bottom of the air action chamber is transferred to the hydraulic damper chamber. What is claimed is: 1. A damper device for a dictation device, comprising: a valve means for causing oil to flow into a hydraulic damper chamber; and an oil throttling passage for squeezing oil in a hydraulic damper chamber and causing it to flow into the bottom of an air action chamber.
