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.

Abstract: A boom damping device includes a fluid pressure cylinder configured to perform an expansion/contraction operation in conjunction with rotational movement of a boom in a roll direction of a working vehicle, a first pressure accumulator into/out of which an operating fluid flows through a first passage with the expansion/contraction operation of the fluid pressure cylinder, a second pressure accumulator into/out of which the operating fluid flows through a second passage with the expansion/contraction operation of the fluid pressure cylinder, and a shut-off switch configured to shut off the first passage and configured to shut off the second passage if at least either one of a right boom and a left boom is not at a working position expanded in a right-and-left direction of the working vehicle.
