摘要： A valve includes: a valve case; and an annular valve body, one of the inner circumference end and the outer circumference end of the valve body being formed as the free end capable of moving towards both sides in the axial direction with respect to the valve case. The valve case has the annular opposing surface capable of opposing to the free end so as to form the gap therebetween, and the guide surface that is positioned on one side of the opposing surface in the axial direction, the guide surface being continuous with the part of the opposing surface in the circumferential direction. The guide surface is inclined in the direction away from the valve body as the distance from the opposing surface is increased.

摘要： Providing an overturn preventing device which can be easily mounted at an appropriate inclination angle. The overturn preventing device includes a damper, a pair of bases, and an angle regulator. The damper is mounted between a top surface of a piece of furniture installed on an installation surface and a ceiling. Both ends of the damper are respectively coupled to the bases so as to be rotatable about respective rotation axes. The first base abuts against the top surface of the furniture and the second base abuts against the ceiling. The angle regulator is attached to the first base. The angle regulator regulates an inclination angle of the damper.
