タ用油入緩衝器。 A cylinder and a plunger that slides on its inner surface.
It consists of a return spring that supports this, and a control rod that penetrates the oil injection hole at the bottom of the plunger. When the plunger is pushed down, the oil in the cylinder passes through the oil injection hole and brakes the falling body due to the resistance. An elevator characterized in that a scattering prevention body formed in a circular shape larger than the oil injection hole is provided at the tip of the control rod, and a dust seal that slides on the inner surface of the plunger is provided on the side of the scattering prevention body. Oil-filled buffer for use.
