Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an opening/closing device with which an opener/closer can be suppressed from being deformed.SOLUTION: An opening/closing device comprises an opener/closer 4 which includes a plurality of joined constituent members 42, guide members 5 which are disposed at both sides in a width direction of the opener/closer, and openings 51 which are formed in the guide members along with an opening/closing direction of the opener/closer and to which terminal portions of the opener/closer in the width direction are inserted freely movable. The opener/closer includes at least one predetermined constituent member 48 in an area which is exposed outside in a closed state, as a constituent member and for the predetermined constituent member, flexural rigidity with respect to forces in directions orthogonal to the width direction and the opening/closing direction, respectively, is greater than that of any other constituent members than the predetermined constituent member.
