Abstract

PROBLEM TO BE SOLVED: To open and close two respective mechanism parts which are closably fitted to a standard mechanism part and consist of the upper and lower steps by operation of the lower limit and also to reduce parts. SOLUTION: The upper step mechanism part 2 and the lower step mechanism part 3 which are closably fitted to a standard mechanism part 1 are connected by a link 7 whose one side is formed into a long hole shape. When the mechanism part 3 is opened, the mechanism part 2 is simultaneously opened by the link 7. The individual mechanism part is opened and closed alike by operation of the lower limit. A lock mechanism is fitted to only the mechanism part 2 and the mechanism part 3 is sandwiched between the mechanism 2 and the standard mechanism part 1. Thereby, the lock mechanism is made one and reduction of parts is enabled.
