PURPOSE: An upper buffer structure prevents an upper buffer hooked and fixed on an upper hooker of a main body from sliding down to the lower part of a buffering rod by the gap between the buffering rod and an operating hole and grease. CONSTITUTION: An operating hole(21) formed inside of an upper buffer(2) constituting a damper(D) has an upper part of diameter identical with or smaller than the diameter of a buffering rod(1) and a sloping part(22) with diameter getting larger to the lower surface. An upper buffer(2) is compressedly attached and fixed on the buffering rod(1) not to slide down to the lower part of the buffering rod(1). |
