Document Type and Number:
Japanese Patent JP2017116001
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fastener hardly coming off from a mounting hole while suppressing an increase in insertion force into the mounting hole.SOLUTION: A fastener includes: a head part 20 having a flange part 30; a pillar part 22 formed in the reverse face of the head part 20; a pair of elastic leg parts 24 extending from the pillar part 22 to the flange part 30 and facing each other across the pillar part 22; and a pair of projections 28 extending from each of the inner surfaces of the pair of elastic leg parts 24 to the tip side of the pillar part 22. The elastic leg part 24 has an engagement part 40 for being engaged with the back edge of a mounting hole in the outer surface on a free end side. The pillar part 22 has a sliding surface 48 where the projection 28 is slidable inside the elastic leg part 24. The projection 28 is separated from the sliding surface 48 in a free state, slides to the sliding surface 48 when inserting into the mounting hole, and comes into contact with the sliding surface 48 in a mounting state to the mounting hole so as to receive reactive force including components in the expansion direction of the elastic leg part 24.SELECTED DRAWING: Figure 1
