ABSTRACT:
A passage opening and closing device has first and second doors for respectively opening and closing passages defined in a case. The first and second doors have first and second rotation shafts, respectively. Each of the first and second rotation shafts includes a projection on its first end and a cylindrical portion defining an engaging hole on its second end. When the first and second doors are assembled in a first assembled condition where the projections extend in opposite directions and the cylindrical portions are rotatably engaged with a second supporting portion of a shaft receiving portion, the first and second rotation shafts are independently rotatable. When the first and second doors are assembled in a second assembled condition where the projection of the second rotation shaft is engaged with the engaging hole of the first rotation shaft, relative rotation of the first and second rotation shafts is restricted.
