PROBLEM TO BE SOLVED: To make connection of both members to be hardly released, even if an unintended external force is applied to the mutually connected members.SOLUTION: A locking hook 30 is disposed to a lower member, and a locking port 40 is disposed to an upper member. Locking claw parts 33 are formed to be projected from a pair of locking pieces 32, 32 constituting the lock hook 30. In overlap widths of the locking claw part 33 with first edge parts 41 of the locking port 40, one overlap width and the other overlap width are different from each other in a direction orthogonal to a mutually approaching and parting direction of the locking piece parts 32, 32. A projection part 45 is formed to the locking hole 40 so that the projection part 45 projects from a second edge part 42 which is extended on a side small in overlap width between the first edge parts 41, 41, toward a portion between the locking pieces 32, 32. The projection part 45 restricts deformation of the locking claw part 33, not to exceed a maximum overlap width of the locking claw part 33 with the first edge parts 41. |
