Abstract: There is provided a suspension device capable of improving roll stiffness without deteriorating the durability of a seal and the riding comfort of a vehicle, the suspension device including: a pair of liquid pressure dampers; a first passage which communicates the extension side chamber with the compression side chamber; a second passage which communicates the compression side chamber with the extension side chamber; and two accumulators, in which each of the accumulators includes a casing, a first free piston which defines a gas chamber inside the casing, and a second free piston which defines a first gas chamber and a second gas chamber inside the gas chamber, and a pressure receiving area near the first gas chamber in the second free piston is set to be smaller than a pressure receiving area near the second gas chamber.

Abstract: Enabling an overturn preventing device to be installed even when a space between a top surface of an article and a ceiling is narrow. A bracket of an overturn preventing device is mounted to a piece of furniture to be prevented from overturn. The bracket has a lower part supporting a first base of a damper of the overturn preventing device at a position lower than a top surface of the furniture. The overturn preventing device can be easily installed even when a space between the top surface of the furniture and the ceiling is narrow.
