LOCK STRUCTURE FOR SUPPORT FIXTURE

摘要

PURPOSE:To obtain a lock structure for a support fixture coping with a change in a thickness of a mount plate and a diameter of a mount hole while its anchor is tilted and which is not escaped. CONSTITUTION:When an anchor part 30 is press-fit to a mount hole 36, a tip of a lock piece 34 is elastically in press contact with a rear side of a bracket 38. A tip of an elastic plate 40 extended from an outer side face of a leg 26 is elastically in press contact with a surface of the bracket 38 to energize the anchor part 30 in a retracted direction, then the support fixture copes with a change in a thickness of the bracket 38. When a frame 12 is tilted, a gap 28 formed with the leg 26 facilitates the leg 26 from being tilted and claw pieces 34 are pressed to spread with respect to a force extracting the anchor part 30 by the tilt and in widely press contact with a rear side of the bracket 38 thereby blocking the anchor part 30 from being escaped.
