PROBLEM TO BE SOLVED: To improve the degree of freedom in opening/closing a parting type opening/ closing door while preventing the escape of cold air in a cold insulation storage for farm products. SOLUTION: A front opening part of the cold insulation storage 1 composed of heat insulating panels is provided with left and right doors 2a, 2b opened in a biparting manner. A center pillar 7 formed of heat insulating panels is disposed at the joint part inner side face of the left and right doors 2a, 2b. Left and right hooks 10, 10 and a simultaneous opening impeding bar 14 are interposed and linked between the center pillar 7 and left and right opening/closing handles 5, 5 provided at the left and right doors 2a, 2b. In association with the opening operation of the left handle 5 of the left door 2a, for instance, the center pillar 7 is locked to the right handle 5 of the right door 2b in the closed state through the left hook and the simultaneous opening/closing impeding bar 14. Either one of the left and right doors 2a, 2b can be independently opened/closed, and if either one of the left and right doors 2a, 2b is operated to open, the center pillar 7 is locked to the handle of the other door which is not open, to improve the degree of freedom in opening/closing operation of the left and right doors.
