DOOR OPENING AND CLOSING REGULATING DEVICE

PROBLEM TO BE SOLVED: To provide a door opening and closing regulating device exercising effects of a simple structure, a small number of parts, superior assembly workability and low cost. SOLUTION: In the door opening and closing regulating device, a pressing plate part 63b and an end face 62b of an oblong hole 62a are in a non-engaged state when a sub door 2 is in an opened state, a tip 62c of a stopper rod 62 is advanced to a position in front of a lock fitting 43, and approach of a locking device body 41 to the lock fitting 43 is prevented by the tip 62c of the stopper rod 62 even when one tries to close a main door 1. In closing of the sub door 2, the pressing plate part 63b starts to engage with the end face 62b of the oblong hole 62a when an operating piece part 63a abuts on a rear face of the sub door 2 and receives rearward pressing force, and the tip 62c of the stopper rod 62 is withdrawn toward a housing 61 from the position in front of the lock fitting 43 against energizing force of a spring 64. When the main door 1 is closed after this, the approach of the locking device body 41 to the lock fitting 43 is allowed to allow locking. COPYRIGHT: (C)2004,JPO
