<p>PROBLEM TO BE SOLVED: To provide a suspension device etc. which makes a vehicle height less likely to rapidly lower from a high state to a low state even when electric power supply is stopped.SOLUTION: A suspension device includes: a rear wheel side suspension spring 110 which is disposed between a vehicle body frame of a motor cycle and a rear wheel and supports the vehicle body frame; a support member 141 which moves while supporting the rear wheel side suspension spring 110 and changes a length of the rear wheel side suspension spring 110 thereby changing relative positions of the vehicle body and the rear wheel; and electromagnetic valves, each of which is provided on a fluid flow passage to open and close and changes a pressure of the fluid according to opening/closing thereby moving the support member 141. The electromagnetic valves are a normal close type first rear wheel side electromagnetic valve 170A which is fully closed when electric power is not supplied and a normal open type second rear wheel side electromagnetic valve 170B which is fully opened when electric power is not supplied.</p> |
