SLIDE DOOR RESTRAINING DEVICE

摘要

PROBLEM TO BE SOLVED: To reliably prevent disengagement of a slide door even when a load is applied, while maintaining high durability.SOLUTION: A hook member 5 includes a projection rod part 14 and a strike plate 15 provided in a root part of the projection rod part 14. A catch member 7 includes a cylinder body part 22 having a fitting hole 23 to be loosely fitted to the projection rod part 14 and fitted to the strike plate 15. When the slide door is closed, oscillation of the slide door 3 is suppressed by engagement between the strike plate 15 and the cylinder body part 22. When a load is applied in a vehicle width direction, the fitting hole 23 is locked to the projection rod part 14 to prevent disengagement of the slide door 3.
