PROBLEM TO BE SOLVED: To reverse a direction of increase/decrease of damping force of shock absorbers 20, 22 on a front wheel side and shock absorbers 24, 26 on a rear wheel side in a region with large operating speed and in a region with small operating speed. SOLUTION: Four shock absorbers 20-26 are connected to a control cylinder 30. The control cylinder 30 is provided with a housing main body part 80 internally having two cylinder chambers 124, 126 partitioned by a partition wall part 82, and a piston assembly 72 wherein two pistons 74, 76 are connected to each other by a connection rod 78. Respective absorber chambers 54 are connected to two outside control chambers 160, 166 and two inside control chambers 162, 164 of the pistons 74, 76. A moving direction of the piston assembly 72 is set to be reversed in the region with the small operating speed and in the region with the large operating speed by selecting pressure receiving area of outside pressure receiving surfaces 170, 176 and inside pressure receiving surfaces 172, 174 of the pistons 74, 76, and a damping property of the shock absorbers 20-26.
