て、作動油の流れに抵抗を付与する。 As the inner tube 1 enters, a portion of the hydraulic oil in the lower oil chamber B flows into the upper oil chamber A, and
Hydraulic oil corresponding to the entering volume of the inner tube 1 flows into the hollow cylinder 5 from the lower passages 6A and 6B, and flows into the upper oil reservoir chamber C. Said passage 6A
An electromagnetic damping valve 7 is interposed between
When the armature 7B is attracted against the force C, the valve 7D interlocked with the armature 7B is seated on the seat portion 7E, providing resistance to the flow of hydraulic oil.
