PROBLEM TO BE SOLVED: To precisely adjust the height of a suspension object by making strand passed through annular members provided on each of an overhead constructive member and the suspension object go by way of a lock device having two bores. SOLUTION: To suspend an equipment 40 from an overhead constructive member 37 by using strand 20 and a lock device 23, a first annular member 36 is provided on the overhead constructive member 37 and a free end part 38 of suspension strand is passed through this annular member 36 and a loop 21 of strand. Next, after this free end part 38 is passed through one bore 24 A of the lock device 23, the free end part 38 is passed through a second annular member 39 provided on the equipment 40. Further, the free end part 38 is adjustably suspended by passing the part 38 through the other bore 24B of the lock device 23. The lock device 23 is related to wedge means in the two bores 24A, 24B and a pull-back to the opposite side of an inserting direction can be prevented. Thus, the height of the equipment 40 can be precisely adjusted. |
