Four shock absorbers (20 to 26) are connected to a control cylinder (30). The control cylinder (30) includes a housing body portion (80) having two cylinder chambers (124, 126) which are divided by a partition wall portion (82); and a piston assembly (72) which is formed by coupling two pistons (74, 76) with each other using a coupling rod (78). Two outer side control chambers (164, 166) and two inner side control chambers (160, 162) are connected to respective absorber chambers (54). Pressure receiving areas of outer side pressure-receiving surfaces (170, 176) and inner side pressure-receiving surfaces (172, 174) of the pistons (74, 76) and damping characteristics of the shock absorbers (20 to 26) are set such that a direction in which the piston assembly (72) moves in a region where an operation speed is low is opposite to a direction in which the piston assembly (72) moves in a region where the operation speed is high. |
