ABSTRACT:
An elongation type oil damper includes a cylinder containing oil in the inside, a hollow plunger slidably fitted in the cylinder, containing oil in the inner space thereof and projecting from a rod end of the cylinder for undergoing elongation and contraction strokes, and a floating piston inserted in the inner space of the plunger for axial movement in a state biased toward the end of the plunger projecting into the cylinder. The plunger is provided at the projecting end thereof with communication holes through which the oil in the plunger and the oil in the cylinder join each other and also with a valve capable of being moved axially to close some of the communication holes in the elongation or contraction stroke of the plunger.
