PURPOSE: A structure for connection between structures is provided to insert a busing with a bellows shape into a bushing insertion hole in the connection, thereby making the connection easy and reducing working hours of the connection and manufacturing costs of a connection member. CONSTITUTION: The first structure(110) is provided with a bushing(112) around which a protrusion(112b) having a bellows shape is formed. The second structure(120) is provided with a bushing insertion hole(121) into which the busing is connectively inserted. The protrusion has an entrance surface(112b-1) and a separation surface(112b-2). The entrance surface is contacted with the busing insertion hole when the bushing is connected to the bushing insertion hole. The separation surface is contacted with the busing insertion hole when the bushing is separated from the bushing insertion hole.
