Abstract

The present invention relates to a bellows device having a duplex structure, which is mounted between a first member and a second member opposed to each other and performing a relative movement to each other, the bellows device being flexibly displaced according to the relative movement of the first member and the second member, bellows device comprising: a first flange fixed to the first member, a first bellows pipe connected at one end thereof to the first flange, a second flange fixed to the second member, a second bellows pipe connected at one end thereof to the second flange and a connection member located between the first bellows pipe and the second bellows pipe and joined to the other ends of the first bellows pipe and the second bellows pipe, wherein the first bellows pipe is flexibly displaced in an axial direction to vertically connect the first member and the second member with each other according to the relative movement of the first member and the second member but is restricted in a laterally flexible displacement along a plane perpendicular to the axial direction, and wherein the second bellows pipe is flexibly displaced in a lateral direction according to the relative movement of the first member and the second member but is restricted in the axially flexible displacement.
