Abstract: Providing an overturn preventing device which is easy in handling such as carrying. The overturn preventing device includes a damper, a first base portion, a second base portion and a connecting tool. The damper is mounted between a top surface of furniture and a ceiling. An expansion force of compressed gas filling a cylinder is applied to the damper in a direction such that a length of the damper is increased. The first base portion is rotatably connected to one of two ends of the damper and has a first abutting surface which abuts against the top surface of the furniture. The second base portion is rotatably connected to the other end of the damper and has a second abutting surface which abuts against the ceiling. The connecting tool maintains a folded state in which the damper is contracted so that the first base portion and the second base portion come close to each other.

Abstract: The invention relates to a strut rod made of composite material for a suspension of a front axle of a vehicle, including: an upper part coupled to a rod and piston assembly connected to a vehicle body; and a U-shaped lower part including two brackets for fixing a knuckle arm of the vehicle. This strut rod includes means for detecting a crack. This detection means includes at least one additional edge positioned so as to project from an outer surface of the U-shaped lower part of the strut rod in a region where a crack possibly occurs in the case of an accidental shock on a wheel of the vehicle.

Abstract: A damping valve includes a main valve opening and closing a main passage, and a pilot passage reducing a pressure of the upstream of the main passage by a throttle to guide as a back-pressure biasing the main valve to the closing direction. A pressure control valve being disposed on the downstream of the throttle and including a seating portion controlling the back-pressure, and a switching valve including a circular depressed portion opening and closing the pilot passage are integrated and controlled by a single solenoid. The damping valve includes fail passages being branched from the downstream of the throttle to bypass the main valve, and a fail valve opening and closing the fail passage. The switching valve is arranged on the upstream of the pressure control valve in the pilot passage. The fail passages are branched from the upstream of the switching valve of the pilot passage.

Abstract: Providing an overturn preventing device which can be mounted to an article such as furniture irrespective of an installation location of the article and which can prevent the article from being overturned by quakes of an earthquake or the like. The overturn preventing device includes a plurality of dampers mounted between a top surface of the furniture installed on a floor surface and a ceiling. The dampers are compression damper that has a smaller damping force generated during an extending operation than a damping force generated during a compressing operation. The dampers have respective axis lines extending from a ceiling side to the top surface side of the furniture, and the axis lines are downwardly inclined and extend in a plurality of directions in a planar view as viewed from above when the dampers are mounted between the top surface of the furniture and the ceiling.

Abstract: A solenoid valve includes a housing having a cylindrical shape and having a valve path, a spool adjusting an opening degree of the valve path, a coil producing a magnetic force when a current passes therethrough, a first and a second stator core excited by the magnetic force of the coil, a shaft configured to be movable along axial direction together with the spool, a plunger fixed to the shaft and moving in the axial direction by adsorption force acting between itself and the first stator core by the magnetic force of the coil, and a coil spring biasing the spool against the adsorption force acting on the plunger. A spring constant of the coil spring increases as the adsorption force increases by the movement of the plunger.
