<p>PROBLEM TO BE SOLVED: To obtain a suspension device having a simpler configuration.SOLUTION: In a suspension device 100, a cylinder 4 is connected to a wheel 2 and is provided, in its inside, with an upper cylinder chamber 4U and a lower cylinder chamber 4L. A piston rod 16 is connected to a vehicle body 1, is connected to a piston 17, and is provided, in the inside, with a first oil passage 19 which connects either one of the upper cylinder chamber 4U and the lower cylinder chamber 4L to a first port 53 working as an entrance for working oil entering the one chamber. A coil spring 20 is interposed between the vehicle body 1 and the wheel 2, extends or contracts following relative movement between the cylinder 4 and the piston rod 16, and is provided, in the inside, with a second oil passage 29 which connects the other of the upper cylinder chamber 4U and the lower cylinder chamber 4L to a second port 55 working as an entrance for the working oil entering the other chamber.</p> |
