るピストンロンドの潤滑構造。An oil passage is drilled through the piston that slides inside the cylinder to the piston rod side, and a safety valve is installed in the oil passage to release oil to the piston rod side when an overload is applied. , an escape oil passage is formed which communicates with the oil passage and allows escape oil from the safety valve to flow while lubricating the piston connection part on the end side of the piston rod and the drive part connection part on the other end side from the inside. Features a piston rond lubrication structure.
