PURPOSE:To improve detaching workability and to render a mounting work safe and secured, by designing a lock ring for fixing divided rims of flange detachable type for a construction car so as to be dividable into a plurality of pieces. CONSTITUTION:A lock ring 6A is divided into several pieces two and more 6b, 6c,.... L shaped cut is provided to the jaw part 6d at both ends of divided lock rings 6b and 6c, so as to be engaged with each other, and jaws 6e and 6f of both lock rings 6b and 6c can be jointed by a bolt 7 being screwed into screw holes 8 and 9. On the other hand, relief surfaces 10 and 11 are formed at both ends of divided lock rings 6b and 6c. With such an arrangement, the lock ring 6A can be fitted to a gutter groove easily and positively, and the lock ring and the gutter groove can be prevented from being broken or deformed during work. |
