摘要： Included are: a first supporting member; a second supporting member arranged to be spaced away from the first supporting member in a main load direction; an elastically deformable diaphragm forming a closed space by connecting the first supporting member and the second supporting member; a detection unit detecting a change of a relative distance between the first supporting member and the second supporting member, and producing a mechanical output of the change of the relative distance; and a controlling member capable of discharging air in an inside of the closed space S to an outside of the closed space S in response to the mechanical output from the detection unit. Thereby, an air spring having a mechanism for suppressing an abnormal rise of a vehicle height without deteriorating the diaphragm can be provided.

摘要： A flexible gear coupling includes two external gears and two internal gears meshing with the respective two external gears. A tooth root crowning radius of each external gear is smaller than a tooth tip crowning radius of the external gear. The external gear is formed such that a reference tooth height that is a tooth height at a tooth width direction middle position is smaller than an end tooth height that is a tooth height at a tooth width direction end position. A ratio of the end tooth height to the reference tooth height is set to 1.21 or more, and/or a ratio Rc/Rb of the tooth root crowning radius to the tooth tip crowning radius is set to 0.37 or less.
