FASTENING DEVICE FOR SLEWING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a fastening device for slewing structure capable of releasing the fastening easily in an emergency without requiring tools while it is firmly fastened to floor surface or the like in ordinary time. SOLUTION: This fastening device of the slewing structure is equipped with a pressure welded member 11 having a first sloped surface 11a on a floor surface 2, and a member to be pressure welded 12 having a second sloped surface 12a with which a pushing force by the first sloped surface 11a increases gradually when a receptacle for sliding doors 1 is slewed in the fastening direction and it approaches to the fastening position. The member to be pressure welded 12 is attached directed at the outer side of the tangential direction of a slewing circle of the receptacle for sliding doors if the second sloped surface 12a is outwards relative to the tangential direction of the center of stewing of the receptacle, and also attached directed inwardly from the tangential direction of the slewing circle of the receptacle if the second sloped surface 12a is directed inwardly relative to the center of slewing.
